title: [Rhythmic photostimulation and a number of alpha-rhythm dipoles in the human brain].
abstract: Dynamic study of the equivalent current dipoles (ECDs) of alpha rhythm in the human brain was performed in a one-dipole model. The number of ECDs was shown to be dependent on the time course of visual stimulation, on the phase shift of triggering of flickers with alpha-rhythm frequency from alpha-wave, as well as on the type of visual illusions produced in subjects by this stimulation. The data are discussed in accordance with the "scanning hypothesis" that predict a certain functional meaning of the spreading alpha-wave for cortical processing of sensory information in the human brain.
