摘要： An integrated switch matrix for a medical device system used for long-term monitoring of electroencephalogram (EEG) signals and mapping of the brain through cortical stimulation is configured to switch functions of various electrodes associated with the system in response to user needs. The programmable switch matrix is integrated in an EEG recording device and allows for connecting any patient electrode(s) to a ground circuit, connecting any patient electrode to a common reference, connecting a selected common reference to any or all recording device(s) in the system and, connecting any patient electrode(s) to anode and/or cathode outputs of a neurostimulator for multi-contact cortical stimulation.
