Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was presented in event-related fMRI and behavioral paradigms. Word pairs varied in terms of semantic relatedness and the connectivity between associates.

- The study aimed to explore the surface complexity of the prefrontal cortex and hemispheric asymmetry in first-episode schizophrenia patients.
- MRI scans were conducted on three groups: first-episode schizophrenia patients, first-episode affective psychosis patients, and age-matched healthy controls.
- Results indicated that while there was no significant difference in cortical complexity, schizophrenia patients showed reduced left-right asymmetry compared to healthy controls, suggesting a neurodevelopmental link to the disorder.
Background: The Heschl gyrus and planum temporale have crucial roles in auditory perception and language processing. Our previous investigation using magnetic resonance imaging (MRI) indicated smaller gray matter volumes bilaterally in the Heschl gyrus and in left planum temporale in patients with first-episode schizophrenia but not in patients with first-episode affective psychosis. We sought to determine whether there are progressive decreases in anatomically defined MRI gray matter volumes of the Heschl gyrus and planum temporale in patients with first-episode schizophrenia and also in patients with first-episode affective psychosis.
