In patients undergoing thalamotomy for intractable pain, multi-contact platinum electrodes were stereotaxically implanted so that the striate cortex and geniculocalcarine tract could be stimulated to evaluate the feasibility of a visual prosthesis. The parameters of stimulation were 50–300 Hz, 0.1–1 msec pulse duration and 0.1–5 mA/phase. Phosphenes were evoked in 7 out of the 17 cases studied. The projection in space of the phosphene depended upon the site of stimulation. The configuration, color and brightness of the phosphene varied from a simple white or colored light to occasionally a multicolored complex pattern. Some phosphenes appeared to blink or flutter, some were stable in position, others appeared to move away radially from the fixation point. Histological studies on 6 of the brains suggested that the phosphenes were more often evoked from the striate cortex than from the geniculocalcarine fibers.

This study is based upon a retrospective analysis of behavior in 34 patients who had thalamotomy for seizure, motor and sensory disorders. Unilateral single lesions, especially in the medial part of the center median nucleus, improved aggression more than hyperkinesia and patho-affect. Bilateral lesions in the center median nucleus resulted in maximum improvement for the three categories of behavior, aggression, hyperkinesia and patho-affect.
