BRAIN STEM SYSTEMS AND BEHAVIOR.
Abstract
During the year covered by this report, work has been performed along the following lines: (1) Regulation of circulation during the wakefulness-sleep cycle. Experiments performed in totally sympathectomized cats have shown that the hemodynamic pattern most usually observed during desynchronized sleep is greatly modified by sympathectomy. (2) Regulation of circulation during emotional behavior. (a) Fighting. Fighting was elicited in unanesthetized cats as a natural reaction to another cat, in which attack was induced by brain stimulation. (b) Preparation for fighting. Cardiovascular changes during preparation for lighting have been compared with those during actual fighting in unanesthetized cats. Several of the functions measured changed differently in the two conditions. It is suggested that some of these differences may derive from the exertion component of fighting which may overwhelm other central neural influences common to fighting and preparation for fighting and related to emotion.
