1. A probe used in deep brain stimulation, the probe comprising:
- a cannula comprising an elongated housing defining an internal aperture and having a base portion with a notch, the housing having a longitudinal axis; and
an electrode configured to be inserted through the aperture of the cannula;
wherein the electrode and notch are configured such that the electrode will contact the notch when inserted in the cannula and be directed out of the cannula at a non-zero angle relative to the longitudinal axis of the housing.

6. A method of mapping a 3-dimensional area of the brain using a semi-microelectrode probe, the method comprising:
-
inserting a sheath into the brain along a straight-line trajectory to position an aperture of the sheath at a first rotational position and depth;
advancing a semi-microelectrode into the sheath to at least the predetermined depth of the sheath;
directing the semi-microelectrode to extend at an angle in a direction away from the straight-line trajectory of the sheath to a first location; and
collecting electrical data from brain tissue in an area proximal to the first location. - View Dependent Claims (7, 8, 9, 10)

11. A system for use in a deep brain stimulation procedure, the computer comprising:
-
a memory unit configured to store data associated with a portion of a brain collected during a deep brain stimulation process; and
a processor configured to cause;
display of a brain/probe image including at least one probe image and a 3-dimensional brain image;
recording of electrical data detected by a deep brain stimulation probe in association with locations in the brain producing the detected data; and
playing of a particular sound corresponding to the recorded data associated with a selected portion of the brain in the 3-dimensional brain image. - View Dependent Claims (12, 13, 14)
