Stereotaxic Implantation for Small Animals: An “Eyelet” Technique

Frequently used methods of implanting electrodes in small animals include the use of small screws to anchor the unit in place, as well as the “wire-bridge” technique. Both of these methods had been used by present investigators and have been found useful. However, a number of animals were found unsatisfactory due to various problems. All of these problems led to the development of the “eyelet” technique of electrode implantation which provided their solutions. The technique and advantages of the stereotactic implantation are described.
