Electroencephalogram recordings in Jhana states: An open dataset
bioRxiv (Cold Spring Harbor Laboratory) July 2, 2026 Marco S. Fabus, Stephen Zerfas, Alex Gruver et al.
Jhana meditation produces states of self-reinforcing bliss that may be useful in clinical and scientific settings, but research has been limited by scarce data and few expert practitioners. To address this, the authors release the largest open-access dataset of electroencephalographic and physiological recordings from expert Jhana meditators, comprising over 100 hours of data from 26 subjects across three retreats. The dataset includes example analysis code. This resource aims to enable broader collaboration and advance understanding of internally generated altered states of consciousness.
