Electrophysiological Assessments in Mentally Retarded Individuals: From Brainstem to Cortex

  • Chapter
Evoked Brain Potentials and Behavior

Part of the book series: The Downstate Series of Research in Psychiatry and Psychology ((DSRPP,volume 2))

Abstract

The problems of mental retardation are complex and can be conceptualized in a number of ways. For example, one can adopt a biomedical model which assumes that basic alterations in the nervous system are the primary cause of mental retardation. Cer tainly, there are numerous genetic and organic insults to the nervous system that support a biomedical model. In contrast, one may consider mental retardation in socio-cultural terms, with emphases being placed upon developmental impairment in infancy and pre-school years, the deleterious effects of social labeling, poor social-vocational adjustment, etc. Yet, in view of growing evidence that environmental deprivation can markedly impair the anatomical, biochemical and functional development of the nervous system (e.g., Greenough, 1975), it is likely that even individuals diagnosed as mentally retarded on socio-cultural grounds may show patterns of neural activity that deviate from normal. Such abnormal neural activity will be manifest to some degree, it is assumed, in patterns of electroencephalographic activity.
