Abstract
The invention provides a multichannel electrode (“MC electrode”) which can perform multiple functions such as recording, stimulating and lesioning simultaneously or sequentially upon a single insertion into a target site. In one aspect, the MC electrode further provides imaging and drug delivery capabilities. The invention also provides interface connectors for connecting the MC electrode to external units such as data acquisition and/or stimulation systems. Although the MC electrode and associated connectors and system(s) provide an optimal way to perform deep brain surgical procedures, the MC electrode and associated connectors and system(s) are useful generally in any technique which relies on recording, activating, and/or inhibiting electrical signals produced by cells.
