[Formation and development of temporary connections with participation of unconscious and conscious stimuli].

Simultaneous elaboration of motor conditioned responses to perceived (PSS) and nonperceived (NSS) sound stimuli was carried out in humans. Development and extinction of electrographic components (skin galvanic response and depression of background rhythmical activity) of the orienting response to NSS was going on significantly slower than that to PSS. The same relations were observed during formation of temporary connections with participation of PSS and NSS being reflected in a more expressed EEG depression reaction in the hemisphere participating in conditioned motor performance. The data obtained are discussed from the point of view of the hypothesis of relative independence of processes of formation of reactions to PSS and NSS even of the same modality.
