Using a multi-electrode probe in creating an electrophysiological profile during stereotactic neurosurgery

A multi-electrode probe system for use during stereotactic neurosurgery, the system comprising:

• a multi-electrode probe adapted to be inserted into an area of a brain that includes a target site to be treated through stereotactic neurosurgery, where the probe includes multiple electrodes on a plurality of shafts that produce output signals corresponding to neuronal activity at multiple sites in the brain;
• a processor that receives the output signals from the electrodes and derives a level of neuronal activity that occurs at each of the multiple sites;
• and
• an output device that produces audible output based on the electrode output signals to provide an indication of the level of concurrent neuronal activity at each of the multiple sites in the brain, wherein each electrode's output is mapped to a unique audible output.
