In the visual and sensorimotor areas of the neocortex and in the hippocampus of alert nonimmobilized rabbits, in response to combinations of light flashes with electrocutaneous limb stimulation an increase was observed of synchronization in the activity of the near-by neurones by activation by inhibitory type (coincidence of the presence and absence of(More)

A study was made on 23 rabbits of the degree of spatial synchronization in response to repeated electrical stimulations of one or simultaneously two cortical areas: the sensorimotor or visual, or simultaneously the sensorimotor and visual, or sensorimotor and precentral respectively. Enhancement of the synchronization induced by the stimulation, globally(More)
1. The probability of occurrence of a motor response of a rabbit to photic stimulation correlates with certain energy characteristics of the theta rhythm of the EEG in the sensorimotor and visual areas of the cortex. 2. Similarity of the mean values of the theta rhythm in different cortical areas is most favorable for the occurrence of a motor response to(More)
Phase shifts in EEG potentials were investigated in the rabbit cortex during photic stimulation and in controls. Degree of phase shift in the predominating theta waves was found to increase gradually with increasing distance between recording electrodes both with and without photic stimulation, pointing to the existence of a phase gradient — the conditions(More)

EEG waves phase relations in the sensorimotor and visual cortical areas were studied in 12 rabbits before and during a motor reaction in response to light stimulation. Phase relations in the background activity were characterized by a considerable dispersion (from 26 to 45 degrees). Light stimulation increased the quantity of synphasic EEG oscillations in(More)
Phasic shifts of cortical biopotentials were studied in rabbits during background activity and photic stimulation. It has been found that in most cases the phasic shift of dominating theta-waves gradually increases with the distance between the electrodes both under conditions of the background activity and photic stimulation. This confirms the presence of(More)
