Behavioral reactions of rats in the early postresuscitation period after systemic circulatory arrest of different duration.

Rats were exposed to systemic circulatory arrest for 10, 12, and 15 min. During the first 10 days after resuscitation exploratory activity of animals depended on the duration of systemic circulatory arrest and was determined by two opposite factors: high reactivity of the central nervous system contributing to intensification of exploratory activity, and impaired general state of survivors (inhibition of animal behavior).
