AB  - The results of E.I. Boyko's school's studies devoted to psychophysiological mechanisms of human verbal-semantic executive functions are examined from the standpoint of modern notions of psychophysiology of consciousness and central executive processes. Original psycho-physiological method of testing stimulus is described. It allows to operationalize I.P. Pavlov's metaphor of presence of the «light spots of consciousness» in a working brain. It is shown that in the process of conscious goal-directed activity focuses of locally increased selective excitation do really appear in human's cerebral cortex. They are created as a result of synthesis and integration of two flows of excitation. The first one is from the active irritants and the second one is from executive influences of second signal system. It is shown that «light spots of consciousness» are often accompanied by «dark spots» in the form of cortical areas of locally decreased excitation. These areas appear in projections of irritants irrelevant to the goal-directed activity. It is shown that method of testing stimulus allows to measure intensity of «light and dark spots of consciousness» and to follow its formation in the duration of time.
