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 ...

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.

Unmarked Emotional States and the Affective Anchoring of Continuity

Sociological Forum, EarlyView.
ABSTRACT Narratives around emotions often foreground remarkable episodes that interrupt situations, producing a “rollercoaster” image of emotional life that leaves its stability underdescribed. To analyze the emotional dimension of social continuity, this article theorizes unmarked emotional states (UES): culturally default, interactionally unobtrusive

Perceptual Priors Update Contextual Feedback Processing in V1

Topics in Cognitive Science, EarlyView.
Abstract Contextual information and prior knowledge facilitate perceptual processing, improving our recognition of even distorted or obstructed visual inputs. As a result, neuronal processing elicited by identical sensory inputs varies depending on the context in which we encounter those inputs.

Beyond the Adult Mind: A Developmental Framework for Predictive Processing in Infancy

Topics in Cognitive Science, EarlyView.
Abstract Predictive Processing has been proposed as the single unifying computation underlying all of cognition, and proponents argue that all psychological phenomena can be explained as consequences of this principle. This theoretical framework has inspired many cognitive scientists and neuroscientists, but it currently has no developmental mechanism ...
