“…It should be pointed out, however, that there are conflicting results concerning CC-morphology in patients with schizophrenia throughout the scientific literature. Significant differences in length, thickness and total area have been reported in numerous studies (13,16,17,21,(45)(46)(47)(48)(49)(51)(52)(53)(54); others have failed to replicate these findings (55)(56)(57)(58)(59). These discrepant results may be explained mainly by methodological problems.…”

“…Structural anomalies of the midline area of the corpus callosum were demonstrated by several MRI scan and postmortem studies (Rosenthal and Bigelow 1972; Bigelow et al 1983; Mathew and Partain 1985; Nasrallah et al 1986; Uematso and Kaiya 1988; Günther et al 1989; Rossi et al 1989; Raine et al 1990). The findings, however, are inconsistent, with reports of increased (Rosenthal and Bigelow 1972) as well as decreased (Rossi et al 1989) midline areas.…”

This article reviews some 50 neuroanatomical postmortem studies published in the last 20 years. The majority of these studies demonstrated various types of subtle anomalies in limbic structures, that is, the hippocampus, parahippocampal gyrus, entorhinal cortex, amygdala, cingulate gyrus, and septum of schizophrenia patients. A number of schizophrenic symptoms might be related to structural and functional disturbances of these brain regions. But these studies also reported subtle changes in parts of the basal ganglia, thalamus, cortex, corpus callosum, and brainstem neurotransmitter systems. Many of the studies, however, are based on small sample sizes and, therefore, must be regarded as preliminary. Cytoarchitectonic abnormalities and lack of gliosis in limbic structures as well as the absence of normal structural cerebral asymmetry in a substantial proportion of patients indicate that these structural anomalies may reflect a disorder of prenatal brain development and argue against the notion that schizophrenia is a progressive degenerative brain disorder.

“…Most previous studies have shown an increase in beta power in schizophrenia patients relative to comparison subjects, 6,9,10,[12][13][14] even though there have been reports of decreased beta power as well. 15 The possible reasons for inconsistencies in spectral power findings in schizophrenia include confounding effects of medications, heterogeneity in symptom profiles of the study samples, chronicity, and gender differences of the patients studied. Differences in recording techniques and data analyses may also interfere with the comparability of results across studies.…”

Electroencephalogram spectral power was estimated at 30 scalp locations in 28 neuroleptic-naive, recent-onset schizophrenia (NRS) patients and 25 healthy comparison subjects in the resting eyes closed condition. Weighted relative power values in the various bandwidths were initially compared between NRS subjects and comparison subjects and subsequently between the positive symptom subgroup, negative symptom subgroup, and comparison subjects, to look for characteristic spectral power profiles of the homogeneous symptom subgroups. Significant differences were noted especially in alpha2, delta, and theta bands between NRS patients and healthy comparison subjects, while the positive symptom and negative symptom subgroups showed characteristic spectral power profiles in alpha1, alpha2, delta, and theta bands.
