Question

Quizplus · Accepted Answer

The stereotaxic apparatus is commonly used for in vivo surgeries on small animals, allowing for precise placement of electrodes or injections in specific regions of the brain. It can also be used for lesioning or recording. However, it is not 100% reliable and requires proper calibration and skillful use by the experimenter. The halo bracket device is not a replacement for the stereotaxic apparatus, but rather another tool used for different types of procedures.
