Propofol attenuates responses of the auditory cortex to acoustic stimulation in a dose‐dependent manner: A FMRI study

Background:  Functional magnetic resonance imaging (fMRI) using blood‐oxygen‐level‐dependent (BOLD) contrasts is a common method for studying sensory or cognitive brain functions. The aim of the present study was to assess the effect of the intravenous anaesthetic propofol on auditory‐induced brain activation using BOLD contrast fMRI.
