Plasticity of central motor pathways in children with hemiplegic cerebral palsy
Abstract
To obtain neurophysiologic evidence for a reorganization of central motor pathways in children who had suffered a cerebral lesion at birth, we performed cross-correlation analyses of multiunit EMG recordings obtained from children with hemiplegic cerebral palsy and marked mirror movements. We found that the motoneuron pools of homologous left and right hand muscles received common synaptic input from abnormally branched presynaptic axons. The results of electromagnetic brain stimulation, cutaneomuscular, and tendon reflex testing suggested that these common inputs are provided by abnormally branched corticospinal tract fibers whose origin is the undamaged motor cortex.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
