Background Symptoms of anhedonia are often central to posttraumatic stress disorder (PTSD), but it is unclear how anhedonia is affected by processes induced by reliving past traumatic memories. Methods Sixty-nine male refugees (PTSD = 38) were interv

One of the most common copy number variants, the 22q11.2 microdeletion, confers an increased risk for schizophrenia. Since schizophrenia has been associated with an aberrant neural response to repeated stimuli through both reduced adaptation and pred

Attention reorganizes connectivity across networks in a frequency specific manner

Autor: S Kwon, Masataka Watanabe, Andreas Bartels, Elvira Fischer

Publikováno v: NeuroImage

Attention allows our brain to focus its limited resources on a given task. It does so by selective modulation of neural activity and of functional connectivity (FC) across brain-wide networks. While there is extensive literature on activity changes,

Background: Neurodevelopmental brain disorders such as schizophrenia, autism and attention deficit hyperactivity disorder are complex disorders with heterogeneous etiologies. Schizophrenia and autism are difficult to treat and often cause major indiv

Visual Motion Responses in the Posterior Cingulate Sulcus: A Comparison to V5/MT and MST

Publikováno v: Cerebral Cortex
Cerebral Cortex (New York, NY)

Motion processing regions apart from V5+/MT+ are still relatively poorly understood. Here, we used functional magnetic resonance imaging to perform a detailed functional analysis of the recently described cingulate sulcus visual area (CSv) in the dor
