[An analysis of the neuronal processes in the activating brain systems of the rat during the acquisition of an instrumental defense reflex].
In chronic experiment, a defensive conditioned reflex was elaborated in rats with electrodes implanted in the reticular oral pons nucleus, cortico-medial group of amygdalar nuclei, ventromedial hypothalamic nucleus and central grey substance of the midbrain. Synchronization of the activity of neuronal groups of emotiogenic formations in the studied brain structures, became enhanced at formation of the conditioned reflex. A dependence was revealed of the level of correlation of limbic neuronal groups activity on functional state of the reticular formation, as well as neurochemical correlation mechanisms. The increase (decrease) of coefficients of correlation of the activity of neuronal ensembles of limbic structures was accompanied by a change of evoked potentials parameters recorded in them.
