title: [The role of the autonomic nervous system in regulating the primary form of sleep in the frog Rana temporaria].
abstract: During the formation of photogenic catalepsy in the grass frog Rana temporaria, studies have been made on successive change of the main functional conditions, which are observed in these animals in natural cycle wakefulness-sleep. It was found that rhythmic illumination readily prolongs two forms of a sleep-like rest. One of them is accompanied by an increase in skeletal muscle tonus, whereas the second--by a decrease in the latter. Original data are presented which reveal the role of the sympathetic and parasympathetic nervous system in regulation of the intensity of various forms of rest in cold-blooded animals. It in suggested that each of the forms of a sleep-like rest is developed under definite relationship between sympathetic and parasympathetic tonus.
