Abstract

Described here are systems for connecting a multiplicity of brain electrodes to an electronic medical device. In some variations, the system comprises at least two leads, where each lead has a conducting means connected to at least one electrode, a reconfigurable electrode switch with control logic attachable to the at least two leads, an electronics control module designed for therapeutic treatment of neurological disorders, and at least one multi-wire connecting cable to connect the electrode switch to the electronics control module. In some variations, the electrode switch is designed to allow transmission of electrical signals between any one of the at least two electrode leads and the control module. In other variations, the electrode switch is designed to allow transmission of signals from any combination of two or more of the electrodes through the connecting cable to the control module.
