A study of the encoding of the basic attributes of an image in the human visual cortex by means of moving dipoles has shown for the first time that, in the 50–300-ms interval after the stimulus, equivalent current dipoles of induced-potential waves lasting about 27 ms are displaced predominantly along curved trajectories. At 110–120 ms from the beginning of the stimulus, there is an abrupt displacement of the dipole from a lateral to a medial position. Two zones of preferred localization of the dipoles are detected in the lateral and medial regions of the visual cortex, whose coordinates coincide with the beginning and end of the trajectories, while the size varies as a function of the phase of the potential. The resulting data are important for estimating the dynamics and kinetics of the processing of the attributes of an image in the visual cortex of the human brain.
