LSD literally unhooks your brain activity from its physical wiring—and that’s exactly why you feel like your 'self' is disappearing.

LSD Relaxes Structural Constraints on Brain Dynamics and Default Mode Decoupling Predicts Ego Dissolution

The Takeaway
Using high-resolution brain imaging, researchers found that LSD causes brain activity to stop following the physical 'tracks' of the brain's structural connectome. The more the brain's electrical signals 'loosened' from its physical anatomy in the default mode network, the more intense the user's experience of 'ego dissolution' became.
From the abstract
Psychedelics profoundly alter conscious experience, yet how they reshape the relationship between brain anatomy and function remains unclear. In particular, it is unknown whether psychedelic states reflect a global disruption of structure-function organization or a frequency- and network-specific reconfiguration of neural dynamics relative to the structural connectome. Here we address this question using source-localized magnetoencephalography mapped onto connectome harmonics to quantify structu
