Study models how ketamine’s molecular action leads to its effects on the brain
… low doses, ketamine increased brain wave power in the fast gamma frequency range (30-40 Hz). At the higher doses that cause unconsciousness, those gamma waves became periodically interrupted by “down” states … the team's model. After a first, moderate dose of ketamine gamma brain rhythm power (warmer colors) emerges. Then as the …
