"For the last 8 years this group has produced radiofrequency lesions in pallidal and thalamic targets to alleviate the symptoms of parkinsonism. In earlier papers we described the stereotaxic surgical technique and an objective method of evaluating clinical results based on the rating by a panel of judges of sequential sound-color motion pictures. This report includes more extensive data and allows definitive conclusions on therapeutic results. The degree of clinical improvement has also been compared with the threshold current required to produce or augment tremor during pre-lesion electrical stimulation of therapeutic targets."

Arch. Neurol., 12. - Chicago, American Medical Association, October 1961, gr.8°, pp.25-29, 5 Figs., orig. wrappers. Offprint! "From the Institute for the Study of Human Neurophysiology, Mount Zion Hospital and Medical Center, San Francisco, California." "Radio frequency (RF) power has long been recognized as a tool useful in pro…duction of experimental lesions in brains of animals and therapeutic lesions in man. However, attempts to quantitate lesion size in terms of input power, current, voltage, or dial settings related to these parameters have not produced uniform results. Among the several reasons for these difficulties are differences in circulation from brain to brain and in different parts of the same brain, and differences in impedance, as well as the problems inherent in an accurate measurement of the power or current actually supplied to the nervous tissue. We felt that quantitation in terms of brain temperature at electrode tip, time of maintenance of temperature, and dimensions of electrode would provide the best index of size of the resulting lesion, since these parameters directly describe the effect by which RF current produces tissue damage.".
