Analysis of neuroelectric implant integrity.

abstract：:Stereotactic interventions at thalamic/subthalamic levels for parkinsonian tremor give the chance to investigate the influence of the supraspinal proprioceptive loops on the tonic component of motor tasks. Studies demonstrate not only a normalization of the late stretch reflex component and a decrease of the pre-refle...
