Article
Background Growing evidence underscores the utility of ketamine as an effective and rapid acting treatment option for major depressive disorder (MDD). However, clinical outcomes vary between patients. Predicting successful response may enable personalized treatment decisions and increase clinical efficacy. Methods We here explored the potential of...

This study aimed to discover predictors of subjective and objective difficulty in emotion perception from dynamic facial expressions. We used a multidimensional emotion perception framework, in which observers rated the perceived emotion along a number of dimensions instead of choosing from traditionally-used discrete categories of emotions. Data w...

Ketamine exerts its rapid antidepressant effects via modulation of the glutamatergic system. While numerous imaging studies have investigated the effects of ketamine on a functional macroscopic brain level, it remains unclear how altered glutamate metabolism and changes in brain function are linked. To shed light on this topic we here conducted a m...
Article
Research in social cognition has shown that our own emotional experiences are an important source of information to understand what other people are feeling. The current study investigated whether individuals project their own affective states when reading other’s emotional expressions. We used brief autobiographical recall and audiovisual stimuli...
Article
Full-text available
Previous fMRI research has applied a variety of tasks to examine brain activity underlying emotion processing. While task characteristics are known to have a substantial influence on the elicited activations, direct comparisons of tasks that could guide study planning are scarce. We aimed to provide a comparison of four common emotion processing ta...

When inferring the mental states of others, individuals’ judgments are influenced by their own state of mind, an effect often referred to as egocentricity. Self–other differentiation is key for an accurate interpretation of other’s mental states, especially when these differ from one’s own states. It has been suggested that the right supramarginal...

Growing evidence suggests that colored light exposure can affect several brain functions in addition to conscious visual perception. Blue as compared to green light has especially been shown to enhance alertness and vigilance, as well as cognitive functions. However, the role of light exposure in studies using non-invasive brain stimulation remains...
Article

Transcranial magnetic stimulation (TMS) is an effective treatment for depression but is limited in that the optimal therapeutic target remains unknown. Early TMS trials lacked a focal target, and thus positioned the TMS coil over the prefrontal cortex using scalp measurements. Over time, it became clear that this method leads to variation in the st...

Background: Early life stress (ELS) affects facial emotion recognition (FER), as well as the underlying brain network. However, there is considerable inter-individual variability in these ELS-caused alterations. As the hypothalamic-pituitary-adrenal (HPA) axis is assumed to mediate neural and behavioural sequelae of ELS, the genetic disposition to...
Article
Background: Cognitive behavioral therapy (CBT) is effective in the treatment of major depressive disorder (MDD). Transcranial Direct Current Stimulation (tDCS) has demonstrated preliminary antidepressant effects and beneficial effects on cognitive function. Objective: We investigated the feasibility and acceptability of using tDCS to enhance the...

Functional connectivity with the subgenual cingulate identifies a target in the frontal cortex for transcranial magnetic stimulation. In this issue, Weigand et al. show that proximity of a patient’s stimulation site to this target predicts antidepressant response.
Article
Background The optimal target in the dorsolateral prefrontal cortex (DLPFC) for treating depression with repetitive transcranial magnetic stimulation (rTMS) remains unknown. Better efficacy has been associated with stimulation sites that are 1) more anterior and lateral and 2) more functionally connected to the subgenual cingulate. Here we prospect...
Article
Full-text available
Early life stress (ELS) is associated with increased vulnerability for depression, changes to the corticotropin-releasing hormone (CRH) system and structural and functional changes in hippocampus. Single nucleotide polymorphisms in the CRH receptor 1 (CRHR1) gene interact with ELS to predict depression, cognitive functions and hippocampal activity....
Article
Full-text available
Background Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for medication refractory major depressive disorder, yet the mechanisms of action for this intervention are poorly understood. Previously we reported that therapeutic effectiveness is related to the strength of connectivity between the site of stimulation and t...
Article
The ability to predict the behavior of others based on their mental states is crucial for social functioning. Previous studies have provided evidence for the role of Oxytocin (OXT) in enhancing the ability to mentalize. It has also been demonstrated that the effect of OXT seems to strongly depend on socio-cognitive skills with more pronounced effec...
Article
Decline in working memory (WM) functions during aging has been associated with hippocampal dysfunction mediated by age-related changes to the corticotropin-releasing hormone (CRH) system. Recent reports suggest that GG-homozygous individuals of single nucleotide polymorphisms (rs110402 and rs242924) in the CRH receptor 1 (CRHR1) gene show increased...
Article
Background Early life stress (ELS) experience is associated with persisting working memory (WM) deficits, changes to the corticotropin-releasing hormone (CRH) system and structural, functional, and epigenetic changes in the hippocampus. Single nucleotide polymorphisms (SNPs) in the CRH receptor 1 (CRHR1) gene interact with ELS experience to predict...

Classic wisdom had been that motor and premotor cortex contribute to motor execution but not to higher cognition and language comprehension. In contrast, mounting evidence from neuroimaging, patient research, and transcranial magnetic stimulation (TMS) suggest sensorimotor interaction and, specifically, that the articulatory motor cortex is importa...
Article
Full-text available
Rationale: Previous studies have shown that oxytocin (OXT) enhances social cognitive processes. It has also been demonstrated that OXT does not uniformly facilitate social cognition. The effects of OXT administration strongly depend on the exposure to stressful experiences in early life. Emotional facial recognition is crucial for social cognition...

The main goal of this study was to assess the usability of a tablet-computer-based application (EmoCogMeter) in investigating the effects of age on cognitive functions across the lifespan in a sample of 378 healthy subjects (age range 18-89 years). Consistent with previous findings we found an age-related cognitive decline across a wide range of ne...

Early life stress (ELS) is associated with altered stress responsivity, structural and functional brain changes and an increased risk for the development of psychopathological conditions in later life. Due to its behavioral and physiological effects, the neuropeptide oxytocin (OXT) is a useful tool to investigate stress responsivity, even though th...

Previous studies suggest that there may be a distinct relationship between spontaneous neural activity and subsequent or concurrent self-specific stimulus-induced activity. This study aims to test the impact of spontaneous activity as recorded in an eyes-open (EO) resting state as opposed to eyes-closed (EC) on self-specific versus non-self-specifi...

Full-text available
Little is known about the neural correlates underlying the integration of working memory and emotion processing. We investigated the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) applied over the left or right dorsolateral prefrontal cortex (DLPFC) on emotional working memory. In a sham-controlled crossover design, pa...

Rationale: The neuropeptide oxytocin (OXT) has been shown to modulate a variety of human social behaviors. However, little is known about its impact on emotional memory processing. Previous research demonstrated both memory-enhancing and memory-impairing oxytocinergic effects. Methods: We investigated the influence of a single (prior to encoding...
Article
The present study aimed at investigating the behavioral effects and neuronal correlates of emotional content and emotional components, i.e. valence and arousal, in the context of a verbal working memory task. Our findings in twenty healthy male subjects demonstrate that (1) word valence has no impact on performance in the verbal working memory task...
Article
Performance monitoring which is a core component of the executive functions has been found to be altered in older adults. Specifically, older adults showed smaller amplitudes of the error-related negativity (Ne/ERN) but increased amplitudes of the correct-related negativity (Nc/CRN), and a lack of adjustment to stimulus-response compatibility. The...
