abstract = {Eleven right-handed subjects performed uni- and bimanual
tapping tasks. Hemodynamic responses as measured with
functional magnetic resonance imaging (fMRI) in the primary
somato-motor cortex (SMC) showed that during bimanual
activity the SMC contralateral to the hand taking the faster
rate was more strongly activated than the SMC contralateral
to hand taking the slower rate. There were no asymmetries;
left SMC activation during the right fast/left slow tapping
condition was comparable to the right SMC activation during
the left fast/right slow condition. A given SMC showed
similar activation levels for bimanual and unimanual
activity (i.e. left SMC activation for right fast/left slow
was similar to left SMC activation for the right fast
unimanual condition). In contrast, a given supplementary
motor area (SMA) showed significantly more activation for
the bimanual than for the unimanual activity. In addition,
an asymmetry was observed during bimanual activities: during
the right fast/left slow activity, the left SMA showed more
activation than the right SMA, but during the left
fast/right slow activity, the right SMA was not
significantly more activated than the left SMA. For
unimanual activities, a clear rare effect (greater
activation for faster rate) was seen in the SMC but not in
the SMA. (C) 1999 Elsevier Science Ltd. All rights
