Stereotaxic atlas

Explanation:

Stereotaxic atlas is a collection of records of a particular animal's brain structure followed by coordinates used in stereotactic surgery.

The Rat brain in Stereotaxic Coordinates provides an atlas of the rat brain. 

For stereotaxic surgery of rats and mouses, it is helpful to understand brain parts which are not cut in the atlas plane. The atlas can be rotated at any angle of approach and then sectioned at any desired angle by a software-free cutting tool.

the correct answer to the question is option C

ATLAS STEREOTAXIC (STEREOTAXIC ATLAS)

"Dr. Ahmed will use a STERIOTAXIC ATLAS or a three-dimensional map of the brain, and a computer, to make sure the electrode is placed in the correct location in the rat.

Explanation: Stereotaxic atlas is a number of records of brain structure of a particular animal accompanied with coordinates used in stereotactic surgery.

Steriotaxic coordinates are usually obtained from a steriotaxic atlas,a steriotaxic atlas is a 3D reconstruction of the brain compiled from serial sections and drawings of sectioned brains. The atlas is constructed such as you move from page to page as if you are travelling through the brain.
