Circular inference in visual cortical hierarchies in schizophrenia

Psychiatry and Clinical Neurosciences, EarlyView.
Aim In schizophrenia, disrupted perceptual processes contribute to positive symptoms. However, it remains unclear how top‐down priors and bottom‐up likelihoods are represented across the hierarchy of visual cortices. To identify these processes within cortical hierarchies, the circular inference model offers a framework to account for the biased ...

Parkinson's disease under dopamine replacement therapy as a human framework for studying addiction‐relevant mechanisms

Psychiatry and Clinical Neurosciences, EarlyView.
Addiction is a chronic relapsing condition characterized by compulsive reward seeking and impaired behavioral control, associated with major individual and societal burden. Mechanistic investigation in humans remains constrained by ethical limitations, uncontrolled exposure histories, and ecological confounds.

Insula–cerebellar functional connectivity associated with somatic symptoms in mood disorders: Differential patterns and longitudinal evidence in major depressive disorder

Psychiatry and Clinical Neurosciences, EarlyView.
Aim This study aimed to identify the resting‐state functional connectivity (rsFC) of insula subregions associated with nonspecific somatic symptoms in mood disorders and to examine whether these connections are state‐dependent. Methods In Phase 1, seed‐based rsFC analyses were performed using 12 insula subregions from the Brainnetome Atlas in patients ...

Transdiagnostic patterns of electroencephalography (EEG)‐derived aperiodic activity across schizophrenia‐spectrum, bipolar, and depressive disorders: A systematic review

Psychiatry and Clinical Neurosciences, EarlyView.
Aperiodic electroencephalographic activity is proposed as a scalable marker of cortical population dynamics relevant to excitation–inhibition balance. However, it remains unclear whether aperiodic parameters represent disorder‐specific abnormalities or context‐sensitive indices of clinically relevant brain states.

Altered prefrontal suppression of striatal activity during intrusive images in obsessive‐compulsive disorder

Psychiatry and Clinical Neurosciences, EarlyView.
Background Current models of obsessive‐compulsive disorder (OCD) emphasize dysfunction in frontostriatal circuits that support flexible behavioral control, leading to impulsive and compulsive actions. However, how these disruptions contribute to obsessions and intrusive thoughts remains poorly understood.
