PHYSIOLOGICAL ORIGINS AND FUNCTIONAL CORRELATES OF EEG RHYTHMIC ACTIVITIES - IMPLICATIONS FOR SELF-REGULATION

Recent neurophysiological findings in relation to thalamocortical mech anisms for sensory processing, together with established anatomical an d expanding functional evidence, have provided a rational theoretical framework for the interpretation of normal and abnormal EEG rhythmic a ctivities. This perspective is integrated here with earlier animal stu dies which were the foundation for many current applications of EEG se lf-regulation as a clinical tool. Basic evidence concerning the origin s, frequency modulation, and functional significance of normal EEG rhy thmic activities is reviewed here in an effort to provide guiding prin ciples for the interpretation of clinical abnormalities and their reme diation with EEG feedback training.
