Morphological alterations of neurons in brains of kittens prenatally exposed to ethanol.

The brains of kittens prenatally exposed to ethanol were studied by the rapid-Golgi method at PN1 and PN9 days. The sizes of the alcohol damaged brains were different. Delayed gyrification was observed on the brain surface. The neurons in subcortical (thalamic) centres and cortical areas developed later than in normal animals. Between days PN1 and PN9 rapid changes occurred in the development of the structural elements of brains of prenatally alcohol exposed kittens.
