Physiological mechanisms of the "arousal response" in animals in a state of hypobiosis.
In a state of hypobiosis in white rats it was found that the previously described [4, 6] "arousal response" is characterized by a flareup of motor activity with a definite coordinated structure of the motor acts in response to a change in the animal's posture. Repeated reproduction of this response leads to a rapid summation of the electromyographic activity and a rise in the temperature. In experiments on heterothermic animals these responses are even more pronounced and are accompanied by a restoration of the original body posture and substantial temperature rise. Such an effective process of heat formation in the bodies of heterothermic animals during the "arousal response" may be associated with the mechanism of "special" awakening under conditions of reduced activity.
