Summary
Nitrous oxide, known for its rapid effects, offers a unique window into how brain networks reorganize. Researchers explored if it blurs the distinct roles of key brain areas. Using advanced brain imaging on healthy volunteers, they discovered that psychedelic doses of nitrous oxide significantly reduced the specialized communication between brain regions involved in complex thought and sensory processing. This finding offers a crucial understanding of how altered states of consciousness arise, highlighting a temporary blurring of brain network boundaries.
Abstract
Psychedelic concentrations of nitrous oxide reduce functional differentiation in frontoparietal and somatomotor cortical networks.
