A-C. Resting state MRI regions of connectivity during the brain during lower dose ketamine publicity in healthy volunteers relative to network of desire 1 (NOI1). The info are connected to the antinociceptive Houses in the drug by assessment of pain relief into a heat pain stimulus and incorporation of pain relief as regressor inside the statistical product. The statistical map presents the variations in connectivity discussed by ketamine (yellow) and by pain relief (green).
