In the article the character of relationship between brain processes and subjective experience is considered. Based on the concept of consciousness as a emergent property of complex brain processes (Sperry, 1969), the authors postulate that mood, as a psychophysiological phenomenon, can be studied using laboratory methods. The experiment is an attempt to establish the relationship between reported mood, described by Thayer's Activation-Deactivation Adjective Check List - ADACL (Thayer 1989) and spectral power density of the brain waves in spontaneous EEG. The results show, that estimation of mood on the Energy-Sleep dimension is correlated negatively with alpha activity and the Tension-Placidity dimension is correlated negatively with theta band power. This may lead to conclusion, that specific variability of brain activation states is differentiated in verbal reports.
