简要总结
The purpose of this study is to investigate how the commonly used anesthetic drug propofol works in the brain to produce loss of consciousness. While under general anesthesia your brain waves will be measured using electroencephalogram (EEG). On a separate day, the patient's brain will be imaged using magnetic resonance imaging (MRI).

研究组 & 干预措施
Active Study Arm
Subjects recruited into this study will be required to undergo a base MRI scan of the brain. On a separate day propofol will be administered with concurrent EEG while subjects respond to stimuli.
干预措施: Propofol (Drug)
结局指标
主要结局
EEG Power in Alpha, Slow, and Delta Bands
时间窗: 11 hours
We used EEG measurements to study the dynamics of loss of consciousness, auditory processing, sensation, and memory under general anesthesia induced with propofol. The EEG data in each of the three specific aims will be analyzed using spectral methods, source localization, and event-related potentials. Through spectral analysis, EEG power (in decibels) in alpha, slow, and delta bands are measured.
