Kinesthetic and somatosensory evoked potentials in patients with Parkinson's syndrome

In patients with Parkinson's syndrome the early components of kinesthetic evoked potentials recorded from the brain differ significantly from those in healthy subjects, whereas the components of somatosensory evoked potentials do not. The observed differences appear to reflect enhanced pyramidal descending influences on the transmission of inhibitory kinesthetic afferent impulses in order to compensate for the excessive excitation in the extrapyramidal system.
