An fMRI sequence for studying the auditory cortex is proposed, allowing for the insertion of silent delays of variable duration between EPI volumes during which auditory stimuli may be presented. Signal steady state conditions are maintained via spin saturation at fixed time points before each EPI volume. The method was successfully tested in vivo, yielding reliable activation of the primary auditory cortex. Results also show that high saturation efficiency is required to avoid erroneous activation patterns in compartments with long T1 such as cerebrospinal fluid.
