Vigilance -- Motivation -- Emotion -- Purposive Behavior II
In the last chapter I outlined a model of behavioral aspects of the perception of sound and music in which a qualitatively and quantitatively graded emotional flow was given a central teleological position. It was suggested that different grades of mental vigilance, possible to manifest in a generalized phenomenological way in EEG-ERP-measures as an expression for biorhythms interacting within and between different systems, are evoked by reticular-limbic reactions to sound and music, and that such processes in a phylogenetical perspective may have executed a synapse-restoring and mnestic function similar to that of sleep, REM dream, and voluntarily evoked changes of consciousness, such as ecstasy. I further argued that, as in sleep and dream, this adjusting and readjusting function is active on the level of the individual, and, in addition, on the level of the social group within the rite and other social ceremonies, most involving dance. Music can, on the slow- wave-side of a fictitious "point zero" of a non-stable equilibrium, induce mental deactivation such as sleep and ecstasy, whereas on the fast-wave-side it releases symphaticotropic-ergotropic arousal.
