“…These findings are consistent with those from earliier work from our lab (Byl et al, 1996;Byl et al, 1997), and are consistent with human imaging results (Bara-Jimenez et al, 1998;Byl et al, 2000;Elbert et al, 1998). Abnormal combinations of receptive fields and large sectors of the somatosensory thalamus with continuous representations were also found in human general dystonia patients (Lenz and Byl, 1999).…”

“…We extend this work to musicians with focal hand dystonia and are able to report evidence for usedependent CNS plasticity. Previously, using neuromagnetic source imaging, we reported a smearing of the homuncular organization of the representation of the digits in primary somatosensory cortex with this population (2). Although this observation does not require causal primacy of the central mechanism, we assumed that behaviorally manipulated usedependent plasticity could potentially be of value in changing both cortical organization and the involuntary discoordination of finger movements.…”

“…This disorder has been recently confirmed by using functional MRI to compare the brain dynamics of the sensory cortex in response to single vs. combined tactile stimulation of the index and middle fingers (6). The present study was designed to investigate whether SMR treatment would also induce observable alterations in the organization of the somatosensory cortex previously shown to be deviant in musicians with focal hand dystonia (2).…”
