Questions related to Affective Neuroscience
Dear fellow researchers,
I am looking for some advice on eye-tracking enabled VR headsets. Currently contemplating between HTC Vive Pro Eye and Pico Neo 3 Pro Eye... Both have built in eye tracking by tobii. Does anyone has any experience with any of them? Or can recommend any other brands?
We are planning to use it for research in combination with EEG and EDA sensors to assess human response to built environment. Any advice is much appreciated.
Hi, I was reading some to papers that use machine-learning approaches in automated emotion classification tasks, but they don’t specify which eye-tracking variables are the most informative to successfully infer the person’s affective state.
I would like that anyone recommend me papers (articles, books or chapters) that report associations between other eye-tracking measures, (besides pupil size, e.g. fixation duration, saccades, blinks, etc.) and affective variables (valence, arousal, or specific emotions)?
The role of astroglia in brain function has been well studied since the use of fluorescence microscopy (in vitro and in vivo two-photon imaging) began in the 1990's.
Verkhratsky and Needergaard (2018) have shown, beyond reasonable scientific doubt, that astrocytes control chemical homeostasis in the whole brain. However, the role of calcium waves in this control of homeostasis is still not consensual among the experts.
The existence of large-scale calcium waves has been proven and imaged 'in vivo' with two-photon fluorescence microscopy. Thrane et al (2012) showed that general anesthetics selectively eliminate these waves. Recently the structure of these waves has been imaged and analysed, but their function(s) is (are) still not well identified.
Thrane AS, Rangroo Thrane V, Zeppenfeld D, Lou N, Xu Q, Nagelhus EA, Nedergaard M. (2012) General anesthesia selectively disrupts astrocyte calcium signaling in the awake mouse cortex. Proc Natl Acad Sci U S A.109(46):18974-9.

The studies I have found on breath holding are focused on holding the breath purposely for several minutes. I am looking for studies of unconscious breath holding while concentrating on a task. Popular terms for this kind of breath holding are 'screen apnea' and 'email apnea'. Since the brain requires ten times more oxygen than any other part of the body, it seems counter-productive to hold the breath while concentrating.
1. Does consciousness exist?
2. If so, what is Consciousness and what are its nature and mechanisms?
3. I personally think consciousness is the subjective [and metaphysical] being that (if exists) feels and experiences the cognitive procedures (at least the explicit ones). I think that at some ambiguous abstract and fuzzy border (on an inward metaphysical continuum), cognition ends and consciousness begins. Or maybe cognition does not end, but consciousness is added to it. I don't know if my opinion is correct. What are potential overlaps and differences between consciousness and cognition?
4. Do Freudian "Unconscious mind" or "Subconscious mind" [or their modern counterpart, the hidden observer] have a place in consciousness models? I personally believe these items as well are a part of that "subjective being" (which experiences cognitive procedures); therefore they as well are a part of consciousness. However, in this case we would have unconscious consciousness, which sounds (at least superficially) self-contradictory. But numerous practices indicate the existence of such more hidden layers to consciousness. What do you think about something like an "unconscious consciousness"?
5. What is the nature of Altered States of Consciousness?
I'm trying to increase the contrast of OsO4 stained brain tissue for x-ray microtomography (a recent scan had very poor contrast). I was wondering if there is any literature precedent for getting denser OsO4 staining by first treating the tissue with an alkene that covalently links itself to biomolecules. My thought is that I could incubate my tissue in 3,4-epoxy-1-butene (or something similar) for a few hours, then lower the pH of the solution, facilitating covalent linkage of the alkenes to the sample's neurons. By coating the cells in alkenes, I would hope to subsequently get denser OsO4 staining and better x-ray contrast. If possible, I would greatly appreciate links to any similar protocols, related suggestions, etc. Thank you!
Hello everyone, I am interested in the role of the body (or corporal dimention) in the educational context, specifically the interactions between teacher and students during the teaching-learning process.
Joint pain is a very common problem with many possible causes - but it's usually a result of injury or arthritis.
Due to the fact that anxiety can increase long term stress, the risk of of inflammation is high. I think This inflammation can cause pain and swelling in joints, affecting every day movements.
I understand that external factors like smell and colour of a room can affect the mood or performance of a person. But to what level is the effect ? Is there any quantitative measure of its influence.
Has anyone did a real life testing ?
Neurolaw is a branch of law that is emerging in our eyes, which must give the answer to the question about the acceptable level of ingrerene in the human brain.
Physicians and scientists agree that having the right research equipment and knowledge about the functioning of the brain they can determine the ability of a person to bear full responsibility for their actions.
Today, neuroscience affects criminal law and forensic science, contributes to the redefinition of such concepts as, for example, sanity, insanity, awareness or incapacitation.
Currently, in most legal systems, psychopaths are considered to be well-versed and aware of their deeds. Because they often do not show remorse they receive high penalties. According to the current state of neurological knowledge, psychopathy is a disease, and a person affected by it has no ability to empathize and experience deep feelings. Should this be a mitigating circumstance during the trial and when the court issues its judgment? Or should you rather examine potential psychopaths and isolate them from society before they commit a crime?
How can you reconcile the medical knowledge, which allows for the possibility of interference in the human brain with the legal regulations that have to uphold human rights?
I see many opportunities and threats here and I am very interested in your opinions.
Happy New 2019!
Do you have an idea about the source of light through which we see dreams ? and what is the source of light through which we can see the colors we see in dreams?
I wish you all the best
Hi all, unfortunately I haven't been able to find a review paper about this topic. Is there anyone who happen to know about a paper that describes ERP components that can be modulated by unconsciously processed stimuli (e.g. stimuli suppressed from awareness in binocular rivalry paradigms)? I'm particularly interested in unconscious processing of emotion. Any suggestion is welcome. Thanks.
prof Theodore Bulloch has published with me as a co autor severaal papers on bicoherence for detection of nonliner features in EEG and ERP (See Nato Advanced Institiute volume on induced oscillatios.
Have you tried bicherence as a feature extraction method ?
Do you know papers that sum up the scientific (physiological or psychological) results on the personal experiences of energy (prana, deqi), characterized often by body sensations (tingling, warmth), linked mostly to oriental/contemplative and body-oriented healing methods?
How would you explain scientifically if your research participants reported to feel a warm tingling flow of energy, when focus on body / practice some meditative method? Were these experiences linked to
- acute local and systemic physiological changes (EMG, SC, ECG, EEG, fMRI)
- or mental processes (attention, memory, emotion)...?
Which we already found: Hui et al., 2007; Raingruber & Robinson, 2007; Beissner, 2015 e.g.
Self/Body objectification was said to be connected to an external self-perspective (i.e. exteroception like visual appearance), while an internal self-perspective (i.e. interoception, body awareness) was said to decrease objectification, shame, surveillance (e.g. Noll & Fredrickson, 1998). So, the personal connection with the body was thought to be more negative when external perspective dominates, and positive, when internal perspective dominates.
I argue, that internal perspective can also be negative (like in the case of somatosensory amplification, catastrophization of body sensations, shame about interoceptive experiences, like fatigue), and external perspective can also be positive (satisfaction with and acceptance of appearance). So the consequence of external/internal perspective might depend on the cognitive evaluation of the different sensory input.
What do you think about this argument? Do you know any paper that investigated this complexity of self-awareness?
I'm currently planning a study about the impact of social interaction (rejection and inclusion) on the cognitive processing of emotional stimuli (negative, positive and neutral). I hypothesize that on a rejection condition, participants would have an impaired performance on a cognitive inhibition task if the stimuli presented is negative. Thus, I expect an interaction between the social interaction and the emotional valence of the stimuli on the inhibition task.
I'm, also, exploring the possibility to test my hypothesis with the EEG. More precisely, I'm interested on the P3 component. I was wondering if it was reasonable to expect a larger amplitude of the P3 exclusively on the rejection condition when negative words have to be processed? In other words, is the P3 affected by this kind of interaction?
Thank you so much and please accept my best regards,
I would like to work in this area, especially for visual awareness and brain, the processing is going through consciousness or unconsciousness?
wish some of the people could help me to give me some Idea as I stuck on my research idea.
There is a debate on conscious/unconscious emotions. I am especially interested in possibility of experiencing unconscious (implicit) empathy.
Hello, i'm working on a research about source localization involved in face processing. I need to do a statistical comparison between two conditions: face perception and scrambled face perception; what software can i use to represent these statistical maps on the subjects MRI?
I wonder if anybody has information about computerized neuropsychological testing tools that both operate without licensing and cover many aspects such as attention, memory, executive function, emotion and social cognition.
Extracting blood from rats that age has been proven to be difficult for many of our lab members.
Can any one send me a good scale for Emotional Regulation for adolescents (18-21) ? or at least direct me to read any informative article about Emotional Regulation ? Besides, I got a question from one of my students asking me "what is the difference between Emotional Intelligence and Emotional Regulation", can any one help me in this question ?!
I am starting a new line of research which includes specific hypotheses about activity in several reward-related regions. I would like to complement the whole-brain analysis with an ROI approach.
Reading through the literature, there seem to be several common tasks (the monetary incentive delay task, the gambling task with high/low/no rewards) and several anatomical localization techniques. Also, some times a specific proton-densiry-weighted scan is conducted (e.g., Tamir & Mitchell, PNAS, 2012).
What is the current state of affairs regarding the optimal strategy for localizing these regions?
We know in metacognition model, metacognition lead to cognitive attentional syndrome which include worry, rumination and cotrol. So i want to know in your project how you define and measure these variables ? Thank you.
I would like to ask if you know if the affective components modulated by the visualization of affective images of the IAPS could be inhibited by the attentional processes that also underlie some psychophysiological variables like the conductance of the skin or the cardiac rate. That is, could the attentional processes hide the typical affective responses of the IAPS images?
Thank you very much to all
I understand that the participants logged each evening for 28 consecutive day the extent to which they felt 20 emotions in the past 24 hours from 0 - 4 (0 being low, 4 being high)
Is there a way to access the exact tool used to collect this data? Was it an online survey?
In the Emotion field, it is usually assumed that negative information is selected more efficiently than positive information. It is reflected in dot-probe tasks with a higher validity effect for negative information than for positive information.
I was just wondering, when you have a validity effect that is higher in one condition (not necessarely in the Emotion field), does it reflect a selection that is more frequent, or a selection that is stronger ?
If I rephrase, concerning the higher validity effect for negative information, does it mean that negative information are selected in more trials than positive information ? Or that negative and positive information are selected with the same frequency, but that the validity effect is stronger for negative information ?
Which questionnaires do you suggest for test anxiety & self-esteem? I prefer to evaluate both state/trait test anxiety but I also want to know the best questionnaires in this area.
Do you have any suggestion or recommendation?
Do you think there are other variables that should be measured too?
could you suggest a specialist in Israel who have profound knowledge and the positive experience in the treatment of affective disorders with MAOI?
i mean:nardil,parnate and augmentation strategy
We are looking for papers about the relation between cognitive flexibility and the hayling task (beyond the relationship between behavioral inhibition and the hayling task). Can anybody help?
In my experiment participants played a horror video-game, while EEG, heart rate and skin conductance measures were taken. According to Davidson's approach-withdrawal model, the frontal EEG alpha asymmetry* (FEA) value
should increase in a fear inducing situation - in my experiment anticipation of fear was proven by heart rate and skin conductance values.
Although, FEA showed no significant correlation with heart rate or skin conductance values, a phenomena was observed right after the fearful stimuli: a significant FEA drop (towards approach tendency). As the frontal areas could only tell not the anticipated emotion, but how the subject handles the given emotion, I would suspect that the moment of fear regulation is captured - when the participants calmed themselves down. That would explain the asymmetry change indicating approach tendency. Also, video was recorded of the participants' face during gameplay; around FEA drops participants tend to (subtly) smile.
Still I'm not sure how to interpret this phenomena and if there's a neurobiological explanation for it.
*(calculated by subtracting the right hemisphere alpha power from the left hemisphere alpha power)
I will be conducting an experiment measuring GSR while simultaneously presenting stimuli through the software package PsychoPy. Rather than reinvent the wheel, I thought I'd ask whether anyone has done this before and whether they have some advice/resources/tips or open-source examples of past experiments. Thanks in advance for any useful answers.
In the next few months I will be setting up an Affective Computing lab. The aim is to quantify the effects of assistive systems and of gamification on both working and learning processes.
I did some research on equipment, but the spectrum is very broad. Alone with encephalography I could spend my complete budget, as there are devices for € 700 up to above € 80.000.
So I would appreciate some recommendations from researchers who have been in a similar situation or currently work in a lab which they think is well-equipped.
The task is for a project that will study associations between executive functions and emotion regulation in older, midlife, and younger adults.
Has anyone investigated using Chronic Stress in individuals as an indicator of unmet needs within a community? Can the recipe of Stress be used to interview individuals with Chronic Stress to identify the causes and triggers the individuals are subject to?
In arts therapies aesthetic experience is assumed to be one of the specific factors of effectiveness of the healing process. We would like to measure moments of aesthetic experience in palliative patients. We look for a suitable psychophysiological marker (such as HRV, hormone measures, electrodermal activity, etc.) that helps us measure aesthetic experinece as unobtrusively as possible. Any ideas are welcome.
i am testing 5 hypotheses regarding humour and mood using existing humour and mood scales. All relationships are significant except one, and I am struggling to understand why. I realise this indicates insufficient evidence to concude a linear relationship between the 2 variables, but why?
I am hopeful someone can share scholarly sources challenging the validity of the "storied self" concept (upon which so much psychological testing is founded). Is it possible that the "self-image" is actually a fabrication? When children approach the social threshold, they are expected to have acquired this (an ego-self inner narrator), and so many face developmental collapse when they don't. Please share any links you may have to trace current research challenging the idea of an epic self. Thanks!
We all may having some sort of traumatic events in our life. Some of them are man made meanwhile some are natural. But every people who faced trauma are not developing PTSD(Post Traumatic Stress Disorder) or accute stress disorder as result of the Trauma. Their emotional Intelligence and Resilience skills play a role in this circumstances.
I kindly expect your idea to develop my research background!
The gene I am working on is is expressed in most of the regions in the brain. I tested context and cued fear conditioning (trained by 5 shocks) in these mice. I have opposite results in context and cued fear conditioning. Here are the details:
1. The knockout mice have increased freezing in consolidation (tested 24h after training) of context fear conditioning when tested 24h after the training.
2. The KO mice have reduced freezing in consolidation (24h) of cued fear conditioning.
3. The KO mice have normal freezing in fear acquisition (tested 1h after training) in either context or cued conditioning.
4. The KO mice have about 20dB increased hearing threshold around the age tested for behavior test, but the threshold is still below the tone applied in cued conditioning. Behaviorally, there is a clear increase of freezing in the mice when the tone starts. Therefore, the KO mice can hear fine.
Theoretically, I think this is possible. Maybe somehow our gene has totally different function in regulating the hipocampus-amygdala and the thalamus-amygdala. Has anyone seen similar phenotypes before? Any other possible explanations for this? Any comments are appreciated.
In 2010, G.van Luijtelaar concluded that these parameters were different in a population of 2x 13 subjects with and without BO. (J. Neuropsychiatry Clin Neurosci. 22;2, Spring 2010).
Since this experiment , I did not see any other study in bigger samples that has confirmed these results.
Thank you for your time and contribution. P. Mesters

I'm working on a research that aims to detect the interest of a student to learn new mathematical skills.. there are several theories and some confusion between the preference, interest and liking.
from your knowledge or experience, what do you think is the most suitable physiological measure to detect interest?
I would like to hear perspectives from both preclinical and clinical scientists in all related fields.
As a psychotherapist I am interested in research on embodied, situated, grounded cognition. Hickoks critique of these approaches seems to be sound. Since I am not an expert in the field of neuropsychology I would like to know if there are arguments to question his position. How do the protagonists of embodied cognition object to his arguments?
Thanks for your ideas, Michael
The traditional view is that cognition and emotion involve separate processes and should be looked at independent of one another. However, many agree that the two are integral to each other and therefore emotion should not be separated from cognition. For instance, there are top-down aspects involved in regulating emotion, that are of a cognitive nature.
There is also a practical side to my question. If you were to publish a computational model pertaining to emotion in some modality, would you consider submitting it to a cognitive science journal?
I am collecting some papers concerning the audiovisual experience in order to come up with a classification of the variables which may be designated for firing the emotional process of this cross-modal fenomenon. I have encountered Annabell Cohen's CAM-int.4 model in one of these but it is not clear to me how it works. Many thanks for your help.
The Facial Action Coding System is built to code the intensity of each action unit. But in studies on emotional facial expressions, how the intensity of global expressions is coded ? I have not found articles that indicate if some rules exist when someone want to measure the global intensity of an expression (e.g. not AU 6+12 separately, but the smile as a whole).
Many thanks for considering my request.
One robust negative extreme point at 450ms was found in my ERP wave on many channels. This component shown in frontal, temporal, central lobes. I want to figure out what that means.
I want to know the impact of emotions fluctuations on 2 outcomes (1 scale and 1 numeric).
I conducted a diary study and asked participants to report significant events and the emotions they aroused, (the diaries were filled immediately after the occurrence of the event). So, different participants reported different emotions for each event, and many participants reported more than one event per day. The outcomes were measured once, daily.
Any creative suggestions for study the impact of emotions fluctuations (apart for MSSD)?
Thanks in advance
There are several interesting papers on ways to measure emotions. For instance, Klaus R. Scherer What are emotions? And how can they be measured?, http://lep.unige.ch/system/files/biblio/2005_Scherer_SSI.pdf
The topic is wide, so contributions come from different scientific areas. My interest is related to applications sprung from IOT. Could you provide hints or examples of brilliant solutions?
I want to work on auditory emotional stimuli and attention and i have no research paper and articles for the reference. I am closely related to my research topic so help me to find some paper.
I'm looking for anatomical changes in parietal and occipital cortices in patients with MDD, but there isn't a lot of literature about it.
I'm referring to results that synchrony is stronger with distressed couples. These are the articles I'm talking about: http://psycnet.apa.org/journals/psp/45/3/587/ and http://psycnet.apa.org/journals/psp/49/1/85/
Any links to critique or later work concerning this topic (by Gottman or some others) would be helpful!
In Descartes' Error -- Antonio Damasio cites a study by Fulton and Jacobsen and evidence that certain kinds of damage to the ventromedial prefrontal areas can result in markedly reduced social interactions and indifference to one's future. What about the immediate present? Does the spontaneous sensory perimeter also lose its affective appreciation? Or is this mainly about projected future moments and directed behavior?
Although it gives quite clear description on the mechanism of empathy,
I didn't ever see the visualization directly deals with the model.
Has anyone visualized the Perception-action model of empathy (Preston & de Waal, 2002, Preston, 2007) in flow-chart-like diagram as a 'process'?
I want to measure the affect for wildlife species among a rural population using questionnaires and structured interviews. Methods like imagery analysis are not suitable for such illiterate, rural people. I need at least 3 easily understandable questions or other measures.
Do you have any idea?
Hi dear all!
In our study we are showing the participants (as potential customers) various types of advertisements and recording their response (microsiemens values) simultaneously thorough Hrv and Electrodermal Activity. I am curious to find out what the microsiemens values would be for instance when the participants like or dislike the ad? In other words would the microsiemens values increase or decrease and how in these emotional states (of like / dislike)? How would we be able to determine like or dislike by looking at microsiemens values? I would be happy if you could provide info about the above.
Is EDA (electrodermal activity, also known as EDR or GSR, galvanic skin response), really a good (robust, reliable, not-subjective) psychophysiological biomarker to measure psychological stress and/or cognitive load? ( i.e. pls. refer only to studies with measurements and analysis of the data and not theoretical background info about EDA)
Damasio et al. propose that somatic markers (feedback signals representing homoeostatic and other bodily states) play a pivotal role in our decision-making processes. The ventromedial prefrontal cortex (VMPFC) is identified as the cerebral module of most relevance to the somatic system. Emotions are understood by SMH advocates as the feeling of the bodily states reported by the markers. Sufferers of damage to the VMPFC have consistently demonstrated anomalous emotional dispositions accompanied by poor decision making (both time-costly and poor outcomes), in the absence of further detrament (no loss of iq, working memory...). The role of emotions in decision making is proposed to be that of restricting the options put up for conscious consideration, based on biasing signals from the body. There is here a suggesting of tacit learning by the body, prior to conscious knowledge. (See the Iowa gambling task)
Smith and Elsworth (1985) and apparently others since then have identified six "cognitive appraisal dimensions" that can help distinguish emotions. Certainty, pleasantness, attentional activity, control, anticipated effort, and responsibility are all features of appraisal patterns underlying distinct emotions, and helping to define them.
Thus, we may find that certain emotions such as happiness and anger may share more relevant features than two emotions of the same valence (positive/negative). Since happiness and anger both construe appraisals of certainty and a sense of individual control over the situation, such cognitive dimensions might play a bigger part in determining the nature of the decisions made than the simple positive/negative valence distinction alone.
Do such considerations necessary undercut the Somatic Marker Hypothesis? Is there room for it to accept such dimensions to our emotions, without selling itself short?
The neuropsychological knowledge can be applied in various ways in the treatment of those affected by a particular brain disorder that impacts on behavior.
Some examples where knowledge related to pathology of the nervous system become useful:
- Make inferences about the normal functioning of the central nervous system
- Different disorders or disturbances can cause similar symptoms
- Some neuropathological conditions may increase the likelihood of other disorders.
- The presence of a certain neuropathological disorder does not mean that there can be another type of disorder
I'd like to know your opinion, and if possible, some articles approaching this topic.
I am looking for journals to cite on the POSITIVE EFFECTS of music on any of these broad areas: brain development, coordination, spatial IQ, cognitive IQ, overcoming learning disabilities, overcoming neurological delays, increased chances of going to college. It is fine if the source is a recent or old journal. Please provide links, thanks.
(When I looked in RG, there was one, but it's still at an accepted article stage.)
I have conducted an fMRI study comparing recovered anorexia nervosa patients to healthy controls on an emotional stroop task. The task consists of fearful and happy faces, overlaid with either the word 'fear' or 'happy'. Thus, a given trial can either be congruent (face and word match) or incongruent (face and word mismatch). The task was to designate if the face was happy or fearful, ignoring the word. Reaction time data showed that it takes longer to respond to incongruent trials compared to congruent trials, which we expected.
However, the fMRI analysis shows that, for the control group, participants had more bilateral amygdala activation during congruent compared to incongruent trials (as shown by the extracted beta weights from left and right amygdala). I expected more amygdala activation for incongruent trials (thinking that an emotional conflict conveys more saliency). I am struggling to understand our observation.
Does anyone have any comments regarding this finding? All comments are highly appreciated!
