[Cortical and subcortical mechanisms of emotional behaviour and vegetative functions in young white rats].
Experiments were carried out on 3 month-old Wistar rats. It was shown that applications of 25% KCL solution on the frontal sections of the both cerebral hemispheres caused a decrease in the amplitude of the potentials and a reformation of the rhythms in the neocortex and subcortical structures. The degree of manifestation, the character and the direction of the changes in the emotional behaviour and vegetative functions (the heart rate) in the young animals with spreading depression in the cortex depended on the time of the reversible inhibition of the neocortex, the initial level of the emotional activity in rats, the type of their emotional behavior, and the functional (compensating) resources of the cerebral systems of the emotional reacting at the level of the cortex-subcortical and intersubcortical interactions. The results of the experiments evidence that the neocortex takes part in the systemic organization of the emotional behaviour and the mechanisms of the control of the vegetative functions.
