體 is spared by 蠶 guillotine, 體 hence stimulation. the maximum conducting tissue between Stimulating electrodes were placed kk electrodes and the spinal through the TS of the y LcGS tricle until the bared tips embraced the pyramid at the level of the trapezoid body. Cranially a complete transec-tion was placed at the collicular level. The lesion caudal to the electrodes was accomplished by means of a spring guillotine. As the blade of this guillotine passes ventrally through the medulla until the curved free border reaches the basiocciput, a central notch in the blade permits the pyramids and basilar artery to escape damage. Figure 1 illustrates, in a macroscopic preparation, the extent of the standard lesion produced by the guillotine at the level of the inferior olives. The medulla was removed from each prepara-tion at the end of the experiment, and the lesion inspected after fixation. Records were obtained by means of fine steel wire microelectrodes insu-lated but for the tip. These could be placed at will in the spinal cord with the aid of a micromanipulator, used with due regard for deformation error. Apr proach to regions of the gray substance from various angles in many experi-ments has diminished the hazard inherent in mechanical error. The highest degree of accuracy cannot be claimed in the absence of histological control
