Psilocin, LSD, mescaline, and DOB all induce broadband desynchronization of EEG and disconnection in rats with robust translational validity

Researchers tested how different psychedelic drugs affect brain electrical activity in rats using EEG recordings. They found that psilocin, LSD, mescaline, and DOB all produced similar patterns of decreased brain activity and reduced communication between brain regions. Importantly, these effects in rats closely matched what scientists observe in human brain studies, suggesting that rats can be useful for understanding how psychedelics work in the brain.

Serotonin and psilocybin activate 5-HT1B receptors to suppress cortical signaling through the claustrum

Researchers found that serotonin and psilocybin (the active compound in magic mushrooms) work through the same brain mechanism to suppress certain neural signals in a brain region called the claustrum. This region controls how different parts of the cortex communicate with each other. The study shows that psilocybin directly targets serotonin 5-HT1B receptors to quiet down signals from one brain area to another, which may explain how psychedelics change cortical network activity and alter consciousness.

Neural mechanisms underlying psilocybin’s therapeutic potential – the need for preclinical in vivo electrophysiology

Psilocybin, the active compound in magic mushrooms, shows promise for treating depression and other mental health conditions. This review examines how psilocybin works in the brain, particularly by affecting brain regions involved in self-reflection and emotion regulation. The authors argue that new brain recording techniques are needed to fully understand how psilocybin produces its beneficial effects, which could help improve treatments for people with severe depression.

Functional relationship between peripheral thermosensation and behavioral thermoregulation

This review explains how your body senses temperature through specialized proteins called TRP channels, which detect hot and cold stimuli. These temperature-sensing proteins help you and other animals regulate body temperature by triggering behaviors like seeking warmth or coolness. Importantly, the review shows that the fatty acid composition of cell membranes can fine-tune how sensitive these temperature sensors are, offering insights into how organisms adapt to different thermal environments.
