Frontal lobes, basal ganglia, temporal lobes--three sites for schizophrenia?
This special issue of the Schizophrenia Bulletin focuses on three brain areas hypothesized to play a role in the etiology of schizophrenia--the frontal lobes, the basal ganglia, and the temporal lobes. Contributors to the issue review evidence from brain-imaging, post-mortem, and psychopharmacological studies that support the involvement of each of these important brain areas in schizophrenia. ...
متن کاملThe frontal lobes, basal ganglia, and temporal lobes as sites for schizophrenia.
Positron emission tomography studies with fluorodeoxyglucose in patients with schizophrenia are reviewed and findings in the frontal lobes, basal ganglia, and temporal lobes summarized from more than 20 published studies. Despite methodological and clinical population differences between studies, most reports indicate that patients with schizophrenia are more likely to be low in these areas tha...

Casual observations of patients with focal frontal lobe lesions often reveal little if any cognitive impairment (Fuster, 1989; Hebb, 1945). At the same time, such patients display an assortment of cognitive deficits upon neuropsychological assessment (Janowsky et al., 1989c; Luria, 1980; Stuss & Benson, 1984). With respect to memory, focal frontal injury does not produce a severe amnesic disord...
متن کاملRegions of the Frontal Lobes
1. Primary Motor Cortex (M1, Brodmann area 4): The primary motor cortex is located on the precentral gyrus just rostral to the central sulcus. It is the source of cortical neurons that will project to the brainstem and spinal cord to activate neurons involved in the control of voluntary movements. It receives input from the neighboring primary somatosensory area (S1, on the postcentral gyrus) a...
متن کاملImpulsivity, frontal lobes and risk for addiction.
Alcohol and substance abuse disorders involve continued use of substances despite negative consequences, i.e. loss of behavioral control of drug use. The frontal-cortical areas of the brain oversee behavioral control through executive functions. Executive functions include abstract thinking, motivation, planning, attention to tasks and inhibition of impulsive responses. Impulsiveness generally ...
