Generators of the rhythmic alpha-activity of human EEG

An attempt to localize brain mechanisms of the rhythmic activity in the rang alpha-rhythm range was made using the equivalent dipole model. It is known that light flickering stimuli with the frequency close to that of the individual alpha-rhythm induce an increase in its spectral power ("photic-driving" phenomenon). It was shown that the activity of the neuronal structures generating the alpha rhythm can be identified by specific frequency of-the light stimulation and localized by means of construction of dipole models. Two sources of the alpha-rhythm in the narrow frequency bands with the maximal resonance responses in the frequencies of 10.1 and 10.5 Hz were localized in the thalamic structures.
