Awakening as Neurophenomenology: An Empirical Case Study Based on EEG
Zenodo (CERN European Organization for Nuclear Research) April 15, 2026 Peer reviewed DOI: 10.5281/zenodo.19591310 via OpenAlex
Summary
The study investigates the neurophysiological changes associated with the 'awakening' state, characterized by a shift from Default Mode Network dominance. Clinical EEG data from one subject showed increased background activity of fast waves (15-22Hz) and low amplitude (5-15μV), along with immediate suppression of alpha rhythm upon eye-opening. These findings indicate that the awakening state is distinct from drug-induced sedation, demonstrating high alertness and acuity.

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."
