The Impact of Oral Promethazine on Human Whole-Body Motion Perceptual Thresholds.
Summary
The investigators will study adaptation of motion perception and manual control in altered gravity, including the effects of a drug (promethazine). The investigators will also study whether promethazine affects motion perceptual thresholds.
