Trial Design

1Treatment groups
Experimental Treatment
Group I: Functional Magnetic Resonance ImagingExperimental Treatment1 Intervention
While music is played Noninvasive functional magnetic resonance (fMRI) imaging will be performed at the University of Michigan Health System, University Hospital, Department of Radiology. The fMRI is done under anesthesia using propofol. The researchers will manually control the infusion of propofol to achieve target effect-site concentrations of 1.2, 1.6, 2.0, and 2.4 μg/ml in a stepwise fashion.
