I.P. Pavlov and modern psychophysiology of attention

Human's orientation activity is executed by frontal and parietal cortex. Early positive component (PI) which is represented in the latent period of saccade reflects movement programming and activation of efferent cortex. Early positive component (P'l) has complex derivation and reflects both perceptive attention processes and activation of eyemovement system connected with prognosis processing. The spike potential reflects activation region brain connected with saccades initiating.
