Study Summary

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).

Primary Outcome

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.
