Technique for enhanced accuracy and reliability in non-human primate stereotaxy

Despite the importance of enhancing the accuracy and reliability of non-human primate stereotaxy, a number of limitations exist using currently described techniques. To overcome these problems, we present a simple universally available approach that combines pre-operative magnetic resonance imaging and the non-surgical creation of reference points (teeth marking). We have found that this approach improves stereotaxic targeting reliability and permits accurate reproducible stereotaxic localization at time points distant from the pre-operative imaging.
