[The interneuronal correlations in the cerebellar cortex in the postresuscitation period]

Quantitative analysis of the neuronal populations of the cerebellar cortex was carried out in white rats after reanimation. Clinical death was modeled by 10-min clamping of the neurovascular plexus near the heart. The material for analysis was collected at the end of ischemia, 90 min, 1, 3, and 7 days after it. There are about 8 neurons of the molecular layer and 250 granular cells per pyramidal neuron in an intact cerebellar cortex of white rats. Staring from day 3 of the postreanimation period, the number of granular cells per pyramidal neuron increases, whereas the ratio of the molecular layer neurons and pyramidal neurons differs but negligibly from the control values over the entire follow-up period. Different sensitivity of various neuron populations to an ischemic exposure leads to the formation of the structural basis for the predominance of stimulating pulsation in the cerebellar cortex and reduces its inhibitory effect on the cerebellar nucleus in the postreanimation period.
