title: Intraoperative electrophysiological recordings during microsurgical DREZ-tomies in man.
abstract: Spinal cord surface evoked potentials were studied during surgery in 20 patients operated upon for pain and spasticity using microsurgical DREZ-tomy (MDT). The goal was to collect data on spinal cord physiology and analyze the effects of MDT. Thanks to a simplified floating tungsten microelectrode, intraoperative unit recordings were obtained from the dorsal horn of 3 spastic and 2 neurogenic pain patients.
