Nitrous oxide (N2O) may elicit antidepressant effects after its elimination from the brain. We sought to investigate whether short-term administration of N2O triggers power within the delta (0.5-4 Hz) and/or theta (4-7 Hz) frequency ranges in the electroencephalogram (EEG) after it's administration, as we have recently seen such rebound effects to N2O in studies conducted on mice. Twenty...
The dissociative anesthetic ketamine regulates cortical activity in a dose-dependent manner. Subanesthetic-dose ketamine has paradoxical excitatory effects which is proposed to facilitate brain-derived neurotrophic factor (BDNF) (a ligand of tropomyosin receptor kinase B, TrkB) signaling, and activation of extracellular signal-regulated kinase 1/2 (ERK1/2). Previous data suggests that ketamine,...
