Abstract:
An interactive computer graphics system has been developed for online use with a two-stage stereotaxic technique in man. The computer plots sagittal sections approximating the region of the brain being stimulated on a display screen located in the operating room. When responses are elicited by electrical stimulation, they are graphically illustrated on the template, accurately positioned at the brain site being stimulated. If such evoked responses do not fit the template, they can be replotted on a modified template in a manner prescribed by the neurosurgeon. Such a system allows optimal localization of subcortical lesion sites.
