Reduction of orbital frontal cortex volume in geriatric depression.
BACKGROUND Postmortem studies have documented abnormalities in the medial orbital frontal cortex in depressed patients. In this study we evaluated whether atrophy of this region can be identified in older depressed patients using magnetic resonance imaging. METHODS Twenty elderly patients meeting DSM-IV criteria for major depression and 20 matched control subjects were studied. The orbital fr...
متن کاملTritiated LSD binding in frontal cortex in schizophrenia.
It has been reported that the binding of tritiated LSD (at 2 or 4 nm) to frontal cortex is reduced in schizophrenia, a finding that has been interpreted as a reduction in the number of serotonin receptors. The present study, however, reveals in a Scatchard analysis of tritiated LSD binding in frontal cortex in the brains of 13 schizophrenic patients that there was no decrease in binding by comp...
متن کاملSchizophrenia and frontal cortex: where does it fail?
Schizophrenia is characterized by cognitive, social, and emotional impairments and by psychotic symptoms. Neuroimaging studies have reported abnormalities within the prefrontal cortex and it has been hypothesized that schizophrenia results from poor or miswired anatomical/functional connections. We have compared the functional connectivity within the frontal cortex in control and schizophrenic ...
متن کاملUncontrolled stress produces severe defect in development of frontal cortex in the rat
One of the most important factors in drug addiction is stress. It has been shown that animals with prenatal stress history are more risky for drug dependence. It have also been shown that frontal cortex play a role in drug dependence. In the present study the effects of two kinds of mild stress during pregnancy on the development of frontal cortex in Wistar rats (250-300 g) were investigated. F...
