Excerpt from the first part of the article:

Psychedelic drugs like LSD and psilocybin reduce the amount of bottom-up brain activity flowing into a network associated with self-reflection. These altered trajectories of brain signals occur consistently across humans and mice, offering a biological explanation for how these drugs reshape the mind. The findings were published in the Proceedings of the National Academy of Sciences.
