Rebound electroencephalographic responses to nitrous oxide exposure in men.

Journal of Neurophysiology May 1, 2025 Petra Valtonen, Stanislav Rozov, Iina Annala et al.

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...

Nitrous oxide use is shifting from general anesthesia to sedation and pain control. Interest in novel uses of nitrous oxide in psychiatry is also growing. Thus, understanding the consequences of using nitrous oxide remains relevant. Previous quantitative research might not have fully captured the whole spectrum of nitrous oxide, whereas qualitative analysis can provide a more comprehensive...
