DOI: 10.1002/da.22583
Abstract: Exposure therapy, a gold‐standard treatment for anxiety disorders, is assumed to work via extinction learning, but this has never been tested. Anxious individuals demonstrate extinction learning deficits, likely related to less ventromedial prefrontal cortex (vmPFC)… read more here.

DOI: 10.1007/s11682-020-00323-5
Abstract: Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are characterized by distorted perception of appearance, yet no studies have directly compared the neurobiology associated with body perception. We compared AN and BDD in brain activation… read more here.

DOI: 10.1016/j.neuroimage.2019.04.021
Abstract: Individuals with impulsive and addictive disorders, including drug addiction, binge eating/obesity, and problem gambling, exhibit both impaired control over behavior and heightened sensitivity to reward. However, it is not known whether such deviation in inhibitory… read more here.

DOI: 10.1016/j.neuropsychologia.2017.01.014
Abstract: ABSTRACT Schizophrenia patients have impaired performance and abnormal brain activation during facial emotion recognition, which may represent a marker of genetic liability to schizophrenia. However, it remains unclear whether the impairment is specific to recognizing… read more here.

Plasticity in brain activity dynamics after task-shifting training in older adults
Sign Up to like & getrecommendations! Published in 2020 at "Neuropsychologia"
DOI: 10.1016/j.neuropsychologia.2019.107285
Abstract: Cognitive control is supported by a dynamic interplay of transient brain activation across fronto-parietal networks and sustained activation across fronto-striatal networks. Older adults show disturbances in this dynamic functional recruitment. There is evidence suggesting that… read more here.

DOI: 10.1016/j.pnpbp.2017.05.022
Abstract: Impaired function of prefrontal brain networks may be the source of both negative symptoms and neurocognitive problems in psychotic disorders. Whereas most antipsychotics may decrease prefrontal activation, the partial dopamine D2-receptor agonist aripiprazole is hypothesized… read more here.

DOI: 10.1016/j.psyneuen.2017.01.019
Abstract: Although conscientiousness has for a long time been considered generally adaptive, there are findings challenging this view, suggesting that conscientiousness might be less advantageous during uncontrollable stress. We here examined the impact of conscientiousness on… read more here.
