Summary

The purpose of this study is to determine the effects of acute pain on long-term memory and conditioned physiologic responses in the presence and absence of low dose nitrous oxide. Functional magnetic resonance imaging will be used to identify the neural correlates of these phenomena. The study will occur over 2 visits and involves no long-term follow up.

Conditions

  • Anesthesia
  • Pain
  • Amnesia

Interventions

DRUG

Nitrous oxide

After a no-drug control period, subjects will inhale nitrous oxide, administered via a breathing circuit and face mask, until a steady-state target end-tidal expired concentration is reached. During the drug condition, subjects will receive low-dose nitrous oxide (% corresponding to Minimum Alveolar Concentration).

DEVICE

Peripheral Nerve Stimulation

Experimental acute pain stimulus will be delivered using a nerve stimulator. These painful shocks will be paired with a fixed number of the experimental cues, in a pattern that appears random to participants.
