Abstract
Cryogenic stereotactic lesions were placed in 55 pulvinar and 9 lateralis-posterior
(LP) nuclei of 49 patients suffering from dystonia, athetosis, spasticity, torticollis,
intractable pain, and other miscellaneous conditions. Ten of 19 cases (52.5%) of dystonia,
10 of 16 cases (62.5%) of athetosis and 7 of 10 cases (70%) of spasticity improved
significantly following the cryogenic lesion. Thirteen patients with primary or secondary
intractable pain were pain-free following surgery. No deleterious effects on motor,
sensory, behavioral, or speech and language functions were noted. Electrophysiological
studies during surgery not only helped in localisation of the pulvinar and LP nuclei
but a wide distribution of evoked potentials from cortex was recorded following their
stimulation. It appears that the pulvinar of man contributes to motor function. The
LP-pulvinar complex is a poly-sensory data processor, contributing to a wide range
of somato-sensory functions.
