title: Comparison of coupling of impulse activity of cerebral cortical neurons and spatial synchronicity of the EEG.
abstract: The coherence of the EEG and the coupling of the impulse activity of neurons of the visual and sensorimotor areas of the neocortex of rabbits, recorded simultaneously from the same electrodes, were compared under chronic experimental conditions. An association was found between the presence and properties of the conjugated functioning of neurons and the coherence of the EEG at various frequencies. Greater coherence of the EEG was observed during the correlated functioning of neurons at frequencies of 3-4.5 Hz than during independent functioning. The neurons discharged in pairs, with a smaller delay between them at the highest level of EEG coherence, and a common source participating more often in their synchronization than at the lowest level of EEG coherence.
