Altered states phenomena induced by visual flicker light stimulation
By Marie Therese Bartossek; Johanna Kemmerer; Timo Torsten Schmidt
A study of 24 participants found that 3 Hz and 10 Hz flicker-light stimulation can produce vivid visual hallucinations and altered-state experiences, focusing on short-term subjective effects rather than long-term benefits or clinical efficacy.

Abstract
About the paper
This 2021 peer-reviewed study examines subjective effects of 3 Hz and 10 Hz flicker-light stimulation in a within-subjects design with 24 participants. It reports vivid visual hallucinations and altered-state ratings, while its scope is short-term phenomenology and measurement rather than long-term benefit or clinical efficacy.

Flicker light stimulation enhances the emotional response to music: a comparison study to the effects of psychedelics
Flicker light stimulation (FLS) enhances emotional responses to music, similar to the effects of psychedelics. In a study with twenty participants, FLS significantly increased reported emotions, particularly "Joyful Activation," and intensity of FLS correlated with higher emotional arousal. These findings suggest further exploration of FLS as a method for inducing altered states of consciousness and its interaction with music-evoked emotions.
Basics of Flickering Light & Pulsed Sound Brain Signaling
Flickering light and pulsed sound serve as neuromodulation signals that can synchronize brainwaves or promote adaptive neuroplastic change. The article differentiates between predictable stimulation, which elicits a frequency-following response, and more complex signaling that incorporates surprise and challenge to foster healthier patterns of attention, mood, and cognition.
Autonomic indicators of self-transcendence: insights from the numadelic VR paradigm
HRV amplitude is identified as a physiological marker of self‑transcendent experiences during a “numadelic” VR paradigm, showing links to subjective self‑transcendence, compassion traits, and emotional improvement, though the study does not establish general clinical efficacy or long‑term effects.
