 Abstract: The cerebellum was suggested to subserve cognitive function by timing operations. In order to conduct a functional imaging study of the basal brain structures, we applied single-shot dual-echo echo planar imaging (EPI). As compared to conventional EPI, image distortion and acquisition time (TA = 1.8 sec / 28 slices) were reduced without deteriorating the contrast-to-noise ratio (CNR). Using TE = 28 and 66 ms at 1.5 T, echoes were combined for locally optimal T2*-weighted CNR. Right Crus I of the cerebellum exhibited increased signal selectively to working memory operations on auditory pause durations (30 140 ms) independent of stimulus parameters.
