Propofol's Hypnotic and Memory Effects
Completed · Has a placebo group
Conditions studied: Healthy
In brief
The purpose of this study is to relate changes in the blood flow in your brain which are measured using magnetic resonance imaging (MRI) to temporary changes in your memory and level of sleepiness while receiving the drug propofol, which is commonly used to induce relaxation or sleepiness for minor surgical procedures. This study will help provide us information which will be useful in understanding which parts of the brain are influenced by these drugs to affect memory and sleepiness.
