Parallel Information Processing in Motor Systems: Intracerebral Recordings of Readiness Potential and CNV in Human Subjects
We performed intracerebral recordings of Readiness Potential (RP) and Contingent Negative Variation (CNV) with simple repetitive distal limb movement in candidates for epilepsy surgery. In 26 patients (in Paris), depth electrodes were located in various cortical structures; in eight patients (in Brn...

| description | We performed intracerebral recordings of
Readiness Potential (RP) and Contingent Negative
Variation (CNV) with simple repetitive distal limb
movement in candidates for epilepsy surgery. In 26
patients (in Paris), depth electrodes were located in
various cortical structures; in eight patients (in
Brno), in the basal ganglia and the cortex. RPs
were displayed in the conteral primary motor
cortex, conteral somato-sensory cortex, and
bilaterally in the SMA and the caudal part of the
anterior cingulate cortices. CNVs were recorded in
the same cortical regiom as the RP, as well as in
the ipsilateral primary motor cortex, and
bilaterally in the premotor fronto-lateral, parietal
superior, and middle temporal regions. In the basal
ganglia, the RP was recorded in the putamen in six
of seven patients, and in the head of the caudate
nucleus and the pallidum in the only patient with
electrodes in these recording sites. We suggest that
our results are consistent with a long-lasting,
simultaneous activation of cortical and subcortical
structures, before and during self-paced and
stimulus-triggered movements. The particular
regiom that are simultaneously active may be
determined by the task context. |
