Psilocybin may trigger long-lasting antidepressant effects by altering neuron firing, not creating new connections

A rat study shows a single dose of psilocybin yields antidepressant-like behavior lasting at least 12 weeks, without lasting spine growth; instead, lasting functional changes in neuron firing (increased excitability and depolarized readiness) in the medial prefrontal cortex likely underlie the effect, with similar results from the 5-HT2A-targeting drug 25CN-NBOH, implicating this receptor; study notes limitations and cautions about translating to humans.

Light-Activated Amino Acids Yield Psychedelic-Style Brain Drugs Without Hallucinations

UC Davis researchers developed a light-driven method that combines amino acids with tryptamine and, after UV exposure, reshapes them into new molecules that activate the serotonin 5-HT2A receptor and may offer psychedelic-like brain benefits without altering perception. In mice, the leading compound fully activated 5-HT2A but did not induce hallucinogenic behaviors (head-twitch responses), leading researchers to pursue further studies on how other serotonin receptors might modulate or suppress perceptual effects.
