Nitrous Oxide for Neuroimaging & Brain Measures

Nitrous Oxide

Nitrous oxide (N₂O) is a rapid-acting NMDA receptor antagonist with emerging evidence for antidepressant efficacy in treatment-resistant depression. Delivered as a 50% N₂O/50% O₂ inhalation mixture over one-hour sessions, it produces rapid mood improvements that can persist for days to weeks. Its established safety record in anesthesia, short session duration, minimal recovery time, and low cost position it as a potentially scalable alternative to IV ketamine and esketamine, though the psychiatric evidence base remains early-stage and no formal psychiatric indication exists. Key open questions include optimal dosing frequency, long-term durability, and the mechanism by which NMDA antagonism without intense psychedelic phenomenology produces antidepressant effects.

IndicationApproximately 264 million people globally suffer from depression, with PTSD affecting around 8 million adults in the United States each year.

Neuroimaging & Brain Measures

Recent advances in neuroimaging have shed light on the neurobiological mechanisms underlying the effects of psychedelics, particularly in the treatment of mental health disorders such as depression and PTSD. Studies involving compounds like psilocybin and MDMA have demonstrated significant changes in brain activity associated with therapeutic outcomes.

Classical and non-classical psychedelic drugs induce common network changes in human cortex

This fMRI analysis study (n=74 total) looks at how three different drugs -; nitrous oxide, ketamine, and lysergic acid diethylamide (LSD) -; affect the way different parts of the brain communicate with each other. By comparing brain scans taken before and during drug use, the study found that all three drugs reduced connectivity within certain networks in the brain, while enhancing connections between different networks. These effects were seen in areas of the brain that are important for our conscious experiences.
