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

The therapeutic potential of psychedelic substances faces limitations due to safety and legal concerns. This study explores a non-pharmacological alternative using a brain-computer interface (BCI) within a Virtual Reality (VR) environment to modulate Default Mode Network (DMN) activity, specifically targeting the Posterior Cingulate Cortex (PCC). We present an offline validation of an EEG...

Dynamic VR Modulation with EEG Feedback for Psychedelic Simulation

2025 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops March 8, 2025 Leon Lange, Jacob Yenney, Y. C. Wu

This study explores approaches to combining real-time electroencephalographic (EEG) with VR to generate synthetic psychedelic experiences. Using a passive brain-computer interface (BCI) that dynamically adjusts virtual content, we aim to elicit neurocognitive states similar to those that characterize psychedelic trips - including attenuation of self-referential thought and diminished engagement...

Bridging Psychedelic VR and BCI: Enhancing User Experience through Adaptive EEG-Guided Neural Modulation

International Conference on Tangible, Embedded, and Embodied Interaction March 4, 2025 Leon Lange, Jacob Yenney, Y. C. Wu

Virtual reality (VR) and psychedelic experiences share significant phenomenological and therapeutic parallels, both offering immersive environments capable of altering perception and evoking profound emotional responses. This study explores the integration of VR with simulated psychedelic experiences using brain-computer interface (BCI) systems to harness their combined therapeutic potential....
