Study Summary

This study is to better understand the systems-level neuronal mechanisms by which general anesthetics produce loss of consciousness.The researchers believe that anesthetics suppress consciousness by disrupting the functioning of large-scale brain networks that support information integration in the brain.

Primary Outcome

Music evoked activity was quantified by measurements of the fMRI BOLD signal. Neural response to a natural auditory stimulus, music, was assessed during both conscious and anesthetized states. Measurements were taken at baseline (30 minutes) and during anesthesia (60 minutes).

Interventions

  • OTHER Functional Magnetic Resonance Imaging (fMRI)
