We studied the effects of injections of xenogenic cerebrospinal fluid (CSF) on behavioral phenomena in rats under open field conditions. Parenteral introduction of xenogenic liquor in adult male and female rats resulted in appreciable changes in the indices of spontaneous motor activity in the open field. Single and double CSF injections promoted intensification of motor and orientational/research activity followed by inhibition of the respective behavioral manifestations. Repeated CSF injections were accompanied by a gradual decrease in the behavioral activity of rats. In males and females, these changes were nearly synchronous. Injections of CSF also influenced the seasonal dynamics of behavioral phenomena in rats and cyclic changes in the activity of females during the estrous cycle. In the whole, CSF injections exerted more powerful effects than the action of main natural biological regulators (photoperiod and sex cycle). The presence of significant amounts of biologically active substances in the liquor, which are responsible for complex effects on links of the neuroendocrine regulatory system of recipients, is the probable basis of the revealed effects.
