title: [Ascending effects of the posterior portion of the hypothalamus on electrical activity of the cerebral cortex in the rabbit during postnatal ontogeny].
abstract: Effects of electrostimulation of the posterior hypothalamus on the neocortical activity of non-anesthetized freely-moving rabbits in the postnatal ontogenesis was studied by means of electroencephalografic method. In rabbits of the first postnatal week the electrostimulation evoked in the neocortex mainly an activation reaction of synchronized character. From the second week of the postnatal age the electrostimulation caused in the EEG of the neocortex a desynchronization reaction. The data obtained show that the posterior hypothalamus may take part in the regulation of the state of sleep and wakefulness in rabbits from the first week of the postnatal age.
