1. A probe for minimally invasive surgery comprising:
a body having a length including a shaft portion and a tapered convex tip portion, the body including a plurality of circumferential ridges spaced apart from one another along the shaft portion so as to define a path for advancement of a retractor rod through said ridges,
a connector electrically connected with a conductive part of the tapered convex tip, the connector capable of being connected to an external source of electricity so that the conductive part delivers electrical stimulation when the conductive part receives electric current; and
a first light emitting device adapted to emit a first color when a first range of electrical activity is detected by the probe and a second light emitting device adapted to emit a second color when a second range of electrical activity is detected by the probe, the first color being different from the second color and the first range being different from the second range.
