Human memory is prone to errors in many everyday activities but also when cultivating hobbies such as traveling and/or learning a new language. For instance, while visiting foreign countries, people erroneously recall foreign language words that are meaningless to them. Our research simulated such errors in a modified Deese-Roediger-McDermott parad...
Background: Fatigue is one of the most common symptoms of multiple sclerosis (MS),
significantly affecting the functioning of the patients. However, the neural underpinnings
of physical and mental fatigue in MS are still vague. The aim of our study was to
investigate the functional architecture of resting-state networks associated with fatigue
in p...
Circadian rhythms (lasting approximately 24 hours) control and entrain various physiological processes, ranging from neural activity and hormone secretion to sleep cycles and eating habits. Several studies have shown that time of day (TOD) is associated with human cognition and brain functions. In this study, utilizing a chronotype-based paradigm,...
Recent works shed light on the neural correlates of true and false recognition and the influence of time of day on cognitive performance. The current study aimed to investigate the modulation of the false memory formation by the time of day using a non-linear correlation analysis originally designed for fMRI resting-state data. Fifty-four young and...
Background:
Cataract is one of the most common age-related vision deteriorations, leading to opacification of the lens and therefore visual impairment as well as blindness. Both cataract extraction and the implantation of blue light filtering lens are believed to improve not only vision but also overall functioning.
Methods:
Thirty-four cataract...
Circadian rhythms synchronize a variety of physiological processes ranging from neural activity and hormone secretion to sleep cycles and feeding habits. Despite significant diurnal variation, time-of-day (TOD) is rarely recorded or analyzed in human brain research. Moreover, sleep-wake patterns, diurnal preferences, and daytime alertness vary acro...
Background: Cataracts are associated with progressive blindness, and despite the decline in prevalence in recent years, it remains a major global health problem. Cataract extraction is reported to influence not only perception, attention and memory but also daytime sleepiness, ability to experience pleasure and positive and negative affect. However...

The goal of this paper is to investigate the baseline brain activity in euthymic bipolar disorder (BD) patients by comparing it to healthy controls (HC) with the use of a variety of resting state functional magnetic resonance imaging (rs-fMRI) analyses, such as amplitude of low frequency fluctuations (ALFF), fractional ALFF (f/ALFF), ALFF-based fun...
Significant differences exist in human brain functions affected by time of day and by peo-ple's diurnal preferences (chronotypes) that are rarely considered in brain studies. In the current study, using network neuroscience and resting-state functional MRI (rs-fMRI) data, we examined the effect of both time of day and the individual's chronotype on...
Background
Some studies suggest that as much as 40% of all causes of death in a group of patients with schizophrenia can be attributed to suicides and compared with the general population, patients with schizophrenia have an 8.5-fold greater suicide risk (SR). There is a vital need for accurate and reliable methods to predict the SR among patients...
Objective: The occurrence of death by suicide in patients diagnosed with bipolar disorder is as much as 60 times greater than in the general population. Even during the state of euthymia patients are characterized by suicide risk.
The aim of the study is to investigate the baseline brain activity in euthymic bipolar disorder patients in regard to...
Background:
Schizophrenia (SZ) and bipolar disorder (BD) patients share deficits in motor functions in the form of neurological (NSS) and cerebellar soft signs (CSS), and implicit motor learning disturbances. Here, we use cluster analysis method to assess (1) the relationship between those abnormalities in SZ and BD and (2) the differences between...

Objectives: The objective of this study was to examine the clinical characteristics of adolescents hospitalized after a suicide attempt or instrumental suicide-related behavior.
Methods: Participants included thirty-six adolescents from the pediatric unit of a Polish hospital who made a nonfatal suicide attempt (SAA) or engaged in instrumental su...
Misophonia is an underexplored condition that significantly decreases the quality of life of those who suffer from it. It has neurological and physiological correlates and is associated with a variety of psychiatric symptoms; however, a growing body of data suggests that it is a discrete disorder. While comorbid diagnoses among people with misophon...
Human performance, alertness, and most biological functions express rhythmic fluctuations across a 24-h-period. This phenomenon is believed to originate from differences in both circadian and homeostatic sleep-wake regulatory processes. Interactions between these processes result in time-of-day modulations of behavioral performance as well as brain...

Objectives:
The aim of our study is to evaluate functional connectivity of cerebellothalamo-cortical networks linking frontal eye fields (FEF) and cerebellar regions associated with oculomotor control: nodulus (X), uvula (IX), flocculus (H X) and ventral paraflocculus (H IX) in bipolar disorder (BD) with the use of resting state functional magneti...
Ryzyko śmierci w wyniku samobójstwa w grupie pacjentów z diagnozą schizofrenii pozostaje stałe w ciągu życia i w przedziale 9-13 % (Chapman i inni, 2015)
Cel:
Cel badania stanowiło określenie zakładanej zależności pomiędzy funkcjonowaniem obwodowego systemu nerwowego i ryzykiem samobójstwa w grupie pacjentów z diagnozą schizofrenii.

Background:
Impulsivity includes, among others, non-adaptive features and difficulties with response inhibition. Research of Apter, Plutchik and van Praag (1993) has indicated on positive relationship between impulsivity and suicidal behaviour. On the other hand, meta-analysis conducted by Anestis et al. (2014) showed that suicidal behaviours are...
This poster presents the study based on the objectification theory (Fredrickson & Roberts, 1997) according to which, women internalize perspective on their body image from mass media, what later leads to habitual monitoring of their bodies and trying to fit them to exaggerated standards. Failure in that results in growth in anxiety levels and body...
One of the groups with the highest rate of suicide attempts are patients diagnosed with schizophrenia. The risk of commiting suicide within a lifetime in this group varies from 5-10%. The aim of the work was to establish the relationship between psychopathological symptoms and the risk of committing suicide in the group of schizophrenia patients ho...
Aims: The goal of the study was a preliminary assessment of the occurrence of post-traumatic stress disorder (PTSD) among patients awaiting major heart surgery and the assessment of the reliability of the Impact of Event Scale-Revised (IES-R). The study was inspired by publications indicating a high rate of PTSD among cardiac patients. Methods: In...
Predictive coding and active inference formulations of the
dysconnection hypothesis suggest that subjects with schizophrenia (SZ)
hold unduly precise prior beliefs to compensate for a failure of sensory
attenuation. This implies that SZ subjects should both initiate responses
prematurely during evidence accumulation tasks and fail to inhibit their...
The objective was to evaluate whether there are differences in facial muscles activity (EMG) and electrodermal activity (EDA) in patients with schizophrenia compared to healthy participants , during affective go/nogo procedure with happy and sad faces, and reactions to pictures of disgust-related stimuli.
Objective was to determine neural basis of suicidal thoughts among patients with schizophrenia using resting state brain activity approach.
