Neuroimaging in schizophrenia commonly shows differences in which brain regions?

• A. Occipital cortex
• B. Hippocampus
• C. Prefrontal and Temporal Cortices
• D. Cerebellum

Answer: (C)

Frontotemporal circuits are the ones most consistently showing differences in neuroimaging for schizophrenia. The prefrontal cortex, especially areas involved in executive function like the dorsolateral prefrontal cortex, often shows reduced activity and structural reductions. This helps explain cognitive difficulties and negative symptoms. The temporal lobes, including the hippocampus, also show structural and functional abnormalities, relating to memory changes and some perceptual/linguistic symptoms. While other regions like the occipital cortex or cerebellum can be involved in some studies, the strongest and most reliable imaging findings cluster in the prefrontal and temporal cortices.
