DMT-induced shifts in criticality correlate with self-dissolution

DMT-induced shifts in criticality correlate with self-dissolution

Psychedelics profoundly alter subjective experience and brain dynamics. Brain oscillations express signatures of near-critical dynamics, relevant for healthy function. Alterations in the proximity to criticality have been suggested to underlie the experiential and neurological effects of psychedelics. Here, we investigate the effects of a psychedelic substance (DMT) on the criticality of brain oscillations, and in relation to subjective experience, in humans of either sex. We find that DMT shifts the dynamics of brain oscillations away from criticality in alpha and adjacent frequency bands. In this context, entropy is increased while complexity is reduced. We find that the criticality shifts observed in alpha and theta bands correlate with the intensity ratings of self-dissolution, a hallmark of psychedelic experience. Finally, using a recently developed metric, the functional excitatory-inhibitory ratio, we find that the DMT-induced criticality shift in brain oscillations is towards subcritical regimes. These findings have major implications for the understanding of psychedelic mechanisms of action in the human brain and for the neurological basis of altered states of consciousness. Significance statement Criticality is characterized by fluctuations occurring on a wide range of spatiotemporal scales and high complexity. Here, we investigate the effects of DMT, a classic psychedelic, on criticality of brain oscillations and in relation to subjective experience. We find that DMT shifts the normally dominant alpha oscillations towards a quieter subcritical state, increasing entropy while reducing complexity, and that this shift correlates with intensity of disruption of the sense of self.

The president has illegally declared war to stop fentanyl trafficking from a country that does not traffic that drug, claiming its leader is trafficking drugs himself, the day after pardoning a former leader of a country who is a convicted drug trafficker. Just to level set

Do you ever think about "doubly special relativity" and get upset

This is pretty obscure

The idea is: The planck length is supposed to be an inviolate limit, but if Lorentz contraction occurs (IE length contraction when something is moving at relativistic speeds), then the effective planck length changes. Observers in different inertial reference frames will measure a different planck length for the same object.

My wife got a family subscription for Duolingo. Now I'm one them... It's actually pretty fun but it has had some unintended consequences. Every once and a while Oscar says "look who's back, back again" and I end up with Without Me by Eminem stuck in my head. For days...
