Sevoflurane's Effect on Neurocognition Study

After a no-drug control period, subjects will inhale sevoflurane, administered via a breathing circuit and face mask, until a steady-state target end-tidal expired concentration of 0.4% (corresponding to 0.2 Minimum Alveolar Concentration) is reached.

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.
