Anomalous self-experiences (ASEs) are a core feature of psychotic disorders and reflect disturbances in ipseity. Impairments in corollary discharge mechanism have been proposed as a neurobiological substrate of ASEs, and an imbalance between brain network integration and segregation, may impair the coherent flow of mental contents, thereby disrupting their fluid and implicit character. However,...
Biotypes of psychoses represent transdiagnostic clusters based on pathological characteristics relevant to this syndrome. This approach seeks to help with the delimitation of groups with external validity within the psychotic syndrome beyond current categories. Our group has previously proposed two biotypes characterized by different cognitive performance and anatomical and functional...
Cannabis use is highly prevalent in individuals with psychosis, raising concerns about its influence on brain function. Electroencephalography (EEG) studies have identified alterations in brain activity in psychosis, including changes in spectral entropy (SE) modulation and connectivity strength (CS). However, the degree to which cannabis use contributes to these alterations remains unclear....
Anomalous self-experiences (ASEs) in schizophrenia have been under research for the last 20 years. However, no neuroimage studies have provided insight of the possible biological underpinning of ASEs. In this novel approach, the connectivity within the default mode network, calculated through a ROI-based analysis of functional magnetic resonance imaging data, was correlated to the ASEs scores...
