The Neurophenomenology of a Self-Induced Transcendental Visionary State: A Case Study.
NeuroImage February 4, 2026 Gabriel Della Bella, Agustina Velez Picatto, Dante Sebastián Galván Rial et al.
A participant who can reliably enter a self-induced non-ordinary state of consciousness (NOC) characterized by vivid imagery, altered bodily perception, and a sense of unity underwent 20 fMRI sessions. Compared to a control group, during the transition into the NOC state, functional connectivity became more variable, indicating temporary destabilization of network organization. In the NOC state, connectivity between brain networks broadly decreased, especially visual cortex coupling with auditory, sensorimotor, and other regions, while frontoparietal and salience networks increased coupling with precuneus and temporal areas, matching reports of inward attention and absorption. Entropy and complexity measures tracked the experience and returned to baseline afterward.
