By carefully monitoring brain activity in a group of healthy volunteers during induced fainting episodes, researchers discovered that certain slow-frequency brain waves, particularly in the delta and theta bands, seemed to be linked with the emergence of these extraordinary mental states, which were marked by visions of otherworldly places, a sense of detachment from the body, and intense euphoria. The findings offer new insights into the neural mechanisms tha…
