SYSTEM AND METHOD FOR CORTICAL MAPPING WITHOUT DIRECT CORTICAL STIMULATION AND WITH LITTLE REQUIRED COMMUNICATION

摘要

An apparatus for cortical mapping and method for using same are disclosed. The apparatus comprises a ECoG electrodes array, a stimulation pad, a neural interface processor, and a computing device for mapping eloquent cortical regions of a subject's brain without using exogenous stimulation and with high resolution.

1. A method for mapping somatosensory and motor cortical regions of a brain of a subject who is undergoing electrocorticoencephalographic (ECoG) recording, the method comprising:
providing an apparatus comprising a computing device, a stimulation pad interconnected to said computing device, and a neural interface processor interconnected to said computing device; implanting an ECoG electrodes array on a surface of the subject's brain; contacting a selected region of the patient's skin with the stimulation pad; producing, with the stimulation pad during a first period of time, stimulation of said selected region; recording with said neural interface processor during the first period of time, a plurality of cortical signals originating in said subject's brain; based upon said plurality of cortical signals, mapping eloquent cortical regions of the subject's brain; and overlaying an image of said ECoG electrode array onto a 3-D mapping of the subject's brain to produce a composite image, said the 3-D mapping including a plurality of landmark locations; and correlating the mapped eloquent cortical regions with said composite image to reduce a risk of causing injury to the mapped eloquent cortical regions during a surgical remediation of epileptic seizures.
