Brain Waves and Psychedelic Drugs: New InsightsBrainwaves, or neural oscillations, are periodic electrical activities that occur when large groups of neurons work together. Researchers now hope that these signals will teach us more about hallucinations and psychoses. Photo: Pär Halje
Researchers at Lund University have developed a method to simultaneously measure brain signals from 128 areas in the awake brains of rats. The technique was used to study the effects of psychedelic drugs on brain activity. Results showed unexpected synchronization among neurons in various brain regions. The study suggests a unique wave phenomenon is linked to the psychedelic experience, despite different effects on individual neurons caused by drugs like ketamine and LSD. The research could offer insights into consciousness, providing a model for studying psychoses and shedding light on the neural basis of consciousness in the context of AI development.
