A new device for cortical stimulation mapping of surgically unexposed cortex. Technical note

J Neurosurg. 1993 Oct;79(4):612-4. doi: 10.3171/jns.1993.79.4.0612.


Intraoperative functional mapping is an integral facet of many supratentorial procedures involving cortical resection. A new device is described that can be used in conjunction with a standard cortical stimulator and strip electrodes to stimulate intraoperative regions of unexposed cerebral cortex. This permits the use of a smaller craniotomy, while providing the ability for functional mapping of large areas of surface cortex.
