Psychedelics Double 5-Hz Brain Oscillations in Visual Cortex to Produce Hallucinations
TL;DR: A 2026 study in Communications Biology found that psychedelic serotonin-receptor activation amplified slow 5-Hz oscillations in visual and memory-related cortex, pointing to a circuit mechanism for altered perception. Key Findings 5-Hz brain waves appear spontaneously and in response to visual input: Researchers detected spontaneous 5-Hz oscillations in mouse visual cortex at a rate of …
