Glutamate dehydrogenase activity in motor cortex neurons during recovery of impaired visual function.

Abstract

1. Recovery of visual function after a period of visual deprivation results in significant normalization of glutamate dehydrogenase activity in nerve cell bodies and processes of layers III and V of the motor cortex. 2. Enzyme activity changes are accompanied by a significant decrease in neuronal size. 3. The normalization rates of neurons in layer III exceed those of neurons in layer V. 4. The morphochemical changes produced in motor cortex neurons during early deprivation of visual function are specific and reversible.
