Simple probe for localized cryogenic blockade in the brain.
The construction of a simple probe utilizing an air-space thermal insulation and circulating coolant for localized cooling of brain tissue is described. Results of isotherm studies in the cerebellum and electrophysiological observations in the motor cortex are presented indicating the effectiveness of localized cooling by the probe.
