Mystical Experience Neuroscience: The Claustrum Is the Ignition Switch for Unity Experiences

This infographic illustrates the hypothesis that psychedelic 'unity' experiences are caused by psilocybin inhibiting the claustrum, dissolving the neural boundaries that normally separate our senses and sense of self.

Psychedelic mystical experiences — feelings of unity, transcendence, sacredness — are the strongest predictor of therapeutic outcome across psilocybin studies (Griffiths et al., 2016, Journal of Psychopharmacology). But what neural mechanism produces the experience of unity?

The claustrum — a thin sheet of neurons beneath the insula — has extensive reciprocal connections with virtually every cortical area. Crick and Koch (2005) proposed it as the "conductor of consciousness." Stiefel et al. (2014) hypothesized that claustrum inhibition could produce the psychedelic state by removing top-down cortical coordination.

Hypothesis: Psychedelic-induced mystical experiences of unity are specifically caused by claustrum inhibition, which removes the boundary-setting function that normally segregates sensory streams and self/other representations. The claustrum normally creates perceptual and cognitive boundaries; its inhibition dissolves them, producing the felt sense of unity. Direct claustrum stimulation will terminate a psychedelic experience.

Prediction: Single-neuron recording in the claustrum during psilocybin administration (in neurosurgery patients with depth electrodes) will show >80% reduction in claustral firing rate during peak mystical experience, with firing rate recovery correlating temporally with resolution of unity experience.
