Stereo-taxis atlas

Explanation:

researchers use a Stereo-taxis atlas to guide an electrode to a specific region in the brain. this is because a Stereo-taxis atlas is a record of the activities/brain structure of an animal accompanied with co-ordinates.

This structure of the brain and the given coordinates guides a researcher when he or she is performing a Stereo-tactic surgery on the animal.

It very important for researchers to use the Stereo -taxis atlas to guide them during the process because without the Stereo - taxis atlas the researcher would perform a terrible job
