Jason's EEG on Nitrous

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.)
