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)

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)
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)
Phase shifts of cortical potentials were studied in rabbits before and during photic stimulation and their importance for irradiation of excitation from the visual to the motor area was examined. Both before and during stimulation variations in phase relationships of various kinds were observed. In most cases, however, with an increase in distance between(More)
associated with its immediate involvement in such brain functions as maintaining the level of consciousness [7], producing motivated and emotional behavior [4, 8], and the acquisition, storage, and reproduction of temporal relationships [4]. Choline-sensitive elements play a significant role in generating neocortical responses to sensory stimuli [9] and to(More)
Phase shifts of cortical electrical activity and their role in excitation irradiation from the visual zone to the motor one were studied in rabbits before and during light stimulation. Different variations of the phase relations were observed both in the background activity and during stimulation. In most cases, however, a gradual increase in the(More)
Unit responses of the sensomotor cortex to paired electrical stimulation and visual cortex, applied either simultaneously or after various delays (from 0 to 200 msec) depend on the order of application of the stimuli and on the interval between them. If stimulation of the sensomotor cortex was used in a conditioning role the response continued unchanged(More)
