[Reaction of the cerebral cortical neurons to complete ischemia].

Changes of morphological and neurophysiological characteristics of pyramidal neurons in response to complete ischemia have been studied by means of vital microscopy of cat and rabbit cortex neurons in addition to some other cytological methods. These responses were found to be complex involving phasic changes in the neuron size, membrane potential and redox potential. Neurons of particular types responded to normo- and hypothermic ischemia differently. Pyramidal neurons retained their vital ability for the whole prolonged period of the complete ischemia (up to 40--60 min).
