Description

Thomas Varley and co-authors dose lab-grown cortical circuits with a psychedelic and watch their information flow change. Most psychedelic neuroscience scans whole human brains, leaving the middle scale of circuits unexplored. Here the drug is N,N-dipropyltryptamine, a serotonin-based psychedelic, applied to rat cortical tissue cultures.

Electrodes recorded three hours of spontaneous activity: one hour clean, one hour with the drug, one hour washed out. The drug reversibly altered how information was processed and shared across the circuit. Dish-grown networks let researchers isolate drug action from expectation and setting, the confounds of human studies. Findings at this scale may anchor theories built from brain scans.
