A three-dimensional reconstruction of the human brain stem.

✓ Advances in computer technology and color graphics have been applied to the sections in a stereotaxic atlas of the human brain stem to enable three-dimensional reconstructions of nuclei and tracts. Techniques for viewing the reconstructed brain stem from multiple directions and in stereo have been achieved. The application of these methods and the use of color graphics are discussed with respect to stereotaxic surgery and computer dissection in neuroanatomical studies.
