TL;DR: Patients with schizophrenia showed both absolutely and relatively reduced metabolic rates in the frontal cortex and in the temporoparietal regions compared with normal controls.

TL;DR: Increased delta activity in the frontal region of patients with schizophrenia in comparison to normal controls is confirmed, and a significant correlation between increased frontal delta and relative reduction in frontal lobe metabolism among patients with psychosis is found.

TL;DR: Functional relationships between cortical areas were assessed by calculating the coherences between different scalp electroencephalogram signals recorded from 13 unmedicated male patients with schizophrenia and 9 normal male subjects, suggesting that "cortical circuits" extending beyond prefrontal areas may be disrupted in schizophrenia.

TL;DR: In this paper, EEG epochs recorded from 12 neuroleptic-free schizophrenic patients and 11 normal control subjects were Laplacian-filtered to highlight activity specific to prefrontal and parietal areas.

TL;DR: Both EEG delta in microvolts and metabolic rate had similar diagnostic sensitivity, but PET had fewer false positives among normals and the left amygdala had the highest sensitivity and percent correct diagnosis of any brain area.
