ANSWER: STEREOTAXIC ATLAS
EXPLANATION:
STEREOTAXIC ATLAS refers to a reference template that has diverse records of brain structure of a specific animal with their associated coordinates.
Researcher uses this template to guide or direct stereotactic surgery (i.e a surgical procedure which makes use of a three-dimensional coordinate system to locate small targets or regions in the body).
