The goal of this experimental medicine clinical trial is to test the hypothesis that nitrous
oxide inhalation will result in a change in neurocircuit function in healthy controls and in
individuals with impulsive aggressive tendencies. The main question aims to answer are: Does
Nitrous Oxide normalize brain circuit function in impulsively aggressive individuals 24 hours
after inhalation. Participants will undergo a 60 minute inhalation session with 50% Nitrous
Oxide (or room air at another session) and then undergo an fMRI scan 24 hours later.
Researchers will compare healthy controls and impulsively aggressive individuals to see if
Nitrous Oxide can normalize the function of cortico-limbic circuits in the latter group.
