The authors report on the development, for studies in man, of a tungsten, glass-coated, light and simple microelectrode, that is implanted by hand in open operative conditions under the microscope and floats freely with the moving target tissue. This technique has provided limited but nevertheless satisfactory unit activity isolations. Intra-operative unit recordings were obtained from the dorsal horns of 2 spastic and 2 neurogenic pain patients. In the latter, dorsal horn deafferentation hyperactivities after a peripheral and a centro-peripheral lesion were recorded, characterized by a continuous, spontaneous and unalterable high frequency hyperactivity.
