abstract = {Two patients with midline tumours and disturbances of
bimanual co-ordination as the presenting symptoms were
examined. Both reported difficulties whenever the two hands
had to act together simultaneously, whereas they had no
problems with unimanual dexterity or the use of both hands
sequentially. In the first patient the lesion was confined
to the cingulate gyrus; in the second it also invaded the
corpus callosum and the supplementary motor area. Kinematic
analysis of bimanual in-phase and anti-phase movements
revealed an impairment of both the temporal adjustment
between the hands and the independence of movements between
the two hands. A functional imaging study in six volunteers,
who performed the same bimanual in-phase and anti-phase
tasks, showed strong activations of midline areas including
the cingulate and ventral supplementary motor area. The
prominent activation of the ventral medial wall motor areas
in the volunteers in conjunction with the bimanual
co-ordination disorder in the two patients with lesions
compromising their function is evidence for their pivotal
role in bimanual co-ordination.},
