TYPOLOGY OF CORTICAL NEURONS AND THEIR ROLE IN ORGANISING INHIBITORY AND EXCITATIVE PROCESSES IN CASE OF VISCERAL EPILEPTIC DISEASE

Abstract

The author presents an overview of literature and his own studies on the structure of temporal lobe as one of the most epileptogenic areas of brain. The epileptic lesions most often result from innate developmental disorders (dysgenesis) and acquired exogenous post-injury and inflammatory brain lesions. At functional and neurochemical levels, these disorders are characterised by prevailing inhibitory and insufficient inhibitory synaptic processes. The cerebral anoxia and ischemia associated with the epileptic seizure as well as experimentally simulated kainite hyperexcitability result in inverse differentiation and elimination of neurocytes via apoptosis, deficient inhibition, disordered synaptic arrangement, and gliosis. Epileptiform activity arises from plastic synapse modifications that appear to enhance efficiency of excitative transmission and disturb the balance of inhibitory and excitative mediatory systems.
