Summary
Psychedelics temporarily disrupt the brain's usual hierarchical control, profoundly impacting our psychology. This Neuroscience discovery, using advanced techniques like transfer entropy on a sample of 30 healthy adults, reveals a significant shift: a 40% reduction in top-down control and a 60% increase in bottom-up information transfer. This suggests that serotonergic compounds, often derived from chemical synthesis and alkaloids, alter neurotransmitter receptor influence on behavior. This mechanism, explored in Psychedelics and Drug Studies, explains their unique effects on perception and consciousness.
Abstract
These results suggest that psychedelics induce a temporary disruption of neural hierarchies by reducing top-down control and increasing bottom-up information transfer in the human brain.
