Lesions in the cerebellum impact cross-modal temporal predictions

This study shows that cerebellar lesions impair cross-modal temporal predictions in visuo-auditory stimulus processing.

Influence of prior beliefs on perception in early psychosis: effects of illness stage and hierarchical level of belief

The paper investigates how prior beliefs influence perception in early psychosis, finding differences in reliance on cognitive and perceptual priors between prodromal, psychotic, and control groups.

Reinforcement learning as an intermediate phenotype in psychosis? Deficits sensitive to illness stage but not associated with polygenic risk of schizophrenia in the general population

The paper assesses reinforcement learning deficits in psychosis risk groups and finds they are not linked to schizophrenia polygenic risk in the general population.

Cortico-thalamic dysconnectivity links with aberrant striatal dopamine in schizophrenia. A simultaneous 18F-DOPA-PET/resting-state fMRI study

Auditory predictions and prediction errors in response to self-initiated vowels

The paper investigates whether forward predictions and prediction errors occur for self-initiated vowels using ERP components, finding N1-suppression for self-initiated speech but not for deviant vowels.

Dopaminergic drug treatment remediates exaggerated cingulate prediction error responses in obsessive-compulsive disorder

This study investigates dopaminergic modulation of prediction error responses in OCD using fMRI and computational modeling, finding bidirectional remediation of exaggerated cingulate signaling with dopamine agonists and antagonists.

Cost evaluation during decision making in patients at early stages of psychosis

This study shows early psychosis patients jump to conclusions due to perceiving higher information sampling costs, not due to noisy decision making.

fMRI salience signals in antipsychotic naive first episode psychosis

This study investigates salience processing abnormalities in first episode psychosis patients using fMRI, finding reduced neural signaling in midbrain and cortical regions for various salience types.

Abnormal reward prediction error signalling in antipsychotic naive individuals with first episode psychosis or clinical risk for psychosis

This study examines reward prediction error signalling in individuals with first episode psychosis and those at risk for psychosis, finding abnormal midbrain and prefrontal cortex activation compared to healthy controls.
