Apart from its function in speech motor control, the supplementary motor area (SMA) has
largely been neglected in models of speech and language processing in the brain. The aim …

The ease with which we perform tasks such as opening the lid of a jar, in which the two
hands execute quite different actions, belies the fact that there is a strong tendency for the …

Behavioral studies in humans have shown that bimanual coordination imposes specific
demands on the central nervous system that exceed unimanual task control. In the present …

The executive control of voluntary action involves not only choosing from a range of possible
actions but also the inhibition of responses as circumstances demand. Recent studies have …

To understand the contribution of the human presupplementary motor area (pre-SMA) in
sequential motor behavior, we performed a series of finger key-press experiments …

The supplementary motor area (SMA-proper) plays a key role in the preparation and
execution of voluntary movements. Anatomically, SMA-proper is densely reciprocally …

Most studies of impaired hand function in children with hemiplegic cerebral palsy (CP) have
focused on either the involved or the non-involved extremity in isolation. Coordination of the …

The execution of coordinated hand movements requires complex interactions between
premotor and primary motor areas in the two hemispheres. The supplementary motor area …

Transcranial magnetic stimulation (TMS) can produce effects not only at the site of
stimulation but also at distant sites to which it projects. Here we examined the connection …

BACKGROUND: Non-invasive brain stimulation such as transcranial direct current
stimulation (tDCS) has been shown to modulate cortical excitability and thereby influencing …
