Abstract
This study aims to explore the neurophysiological mechanisms of the "awakening" state, defined as a shift in consciousness from Default Mode Network dominance to second-order observation. Based on neurophenomenological theory, we hypothesize that awakening manifests physiologically as DMN inhibition, increased cortical excitability, and high energy efficiency. Clinical EEG data from a subject (off anxiolytics for over 6 years) in a long-term self-regulated state revealed: increased background activity of 15-22Hz fast waves across all leads with low amplitude (5-15μV), and immediate alpha rhythm suppression upon eye-opening. The data confirms that the awakening state is not drug-induced sedation, but a specific neurophysiological mode characterized by "high alertness, low internal friction, and high acuity." This study provides physiological evidence distinguishing "drug sedation" from "conscious awakening."
