Enhanced EEG-Based Tracking of DMN Activity Using ICA and EEG Source Localization for a VR Psychedelic Environment

International IEEE/EMBS Conference on Neural Engineering November 11, 2025 Parv Chordiya, Leon Lange, Y. C. Wu

A brain-computer interface within a virtual reality environment can modulate Default Mode Network activity by targeting the Posterior Cingulate Cortex. An EEG processing pipeline combining Independent Component Analysis with source localization derived a subject-specific spatial filter from resting-state data, applied during a virtual psychedelic experience. Compared to traditional parietal-EEG channel selection, the PCC-filtered method revealed significantly enhanced spectral differentiation between baseline and VR states, including a greater decrease in alpha power and increase in delta power during the virtual hallucination, and a larger dynamic range in both alpha and delta power modulations in response to VR scene changes. This approach offers a more sensitive measure of DMN dynamics for closed-loop BCI systems.

Multimodal Analysis of Acute Neurophysiological Effects of Tibetan BöN Tsa Lung Breathwork: Insights into Autonomic and Cortical Resilience Validated with Wearable Ear-EEG

International IEEE/EMBS Conference on Neural Engineering November 11, 2025 Daniel Ehrens, A. Stewart, Akshay Paul et al.

A single session of Tsa Lung, a Tibetan Bön breathwork practice, performed by a Tibetan Bön Rinpoche between two Cold Pressor Stress trials, was associated with increased high-frequency heart rate variability and a reduced LF/HF ratio, indicating enhanced parasympathetic activity and autonomic resilience. Scalp and ear electroencephalography showed increased alpha power and reduced beta/gamma activity during the post-breathwork stress trial, suggesting improved cortical stability. The findings, contextualized with a small untrained control cohort, support breath-centered practices for rapid neurophysiological modulation relevant to stress regulation and neural rehabilitation.
