This is Jason's EEG on nitrous oxide:
Be cool, stay in school, and just say no to drugs.
(At a party a while ago, we decided it might be fun to record someone's
EEG while doing a canister of nitrous. We did that for four people,
three of whose EEGs showed no obvious visible response. The fourth
person did several hits, each one showing very high amplitude ~2Hz
(delta) waves as imaged above for around 20 seconds. Incidentally,
delta waves like this are usually only seen during deep sleep or in
individuals with severe brain trauma.)
