RESUMO

The anterior cingulate gyrus (acg) is involved in mechanisms of attention and emotion, where the right hemisphere is considered to be dominant. One of the models for neuropsychological dysfunction in schizophrenia suggests an impairment in the balance of lateralized functions. Fourteen adult human female brains, having no macroscopic lesions, were used in this study. Seven brains came from female patients with clinical diagnoses of residual schizophrenia (DSM-III-R; APA 1987). Seven female brains were used as controls. Thirteen male brains were also studied, with the sole purpose of establishing the typicality of the female controls. All schizophrenic brains were age matched with control brains. Right laterality for weight (71.4%) and surface (85.7%) was observed in the acg of female control brains. The inversion of this laterality in a significant number of the schizophrenic cases was the most relevant finding in this study.
