Courtesy of Brain dataset from Gordon Kindlmann at the Scientific Computing and Imaging Institute, University of Utah, and Andrew Alexander, W. M. Keck Laboratory for Functional Brain Imaging and Behavior, University of Wisconsin-Madison this is a demonstration of DT-MRI (Diffusion Tensor - Magnetic Resonance Imaging). An advanced medical imaging technique that allows in vivo measuring of location and orientation of nerve fibers in human brain. Water molecules move (diffuse) along nerve fibers, and the diffusion anisotropy can be measured and displayed.

Functional MRI method measures blood oxygen level and thus neuronal activity of the brain. By combining both techniques neural bundles involved in certain activities can be visualized.

Using the resources of the Brain Research Center at UCLA, this film illustrates the development of neuroscience, from its reliance on information from brain injuries and from autopsies, through to new insights discovered with electronic micro-scopes, EEG equipment, PET scans and MRI machines. These new means of exploring the brain have broadened and deepened the extent of research; each has its own uses and methodologies which are elaborated in the film. Throughout DISCOVERING THE HUMAN BRAIN: NEW PATHWAYS TO NEUROSCIENCE, examples of actual research that utilize current technology are presented, including a study on the role of mirror neurons in autism and the mapping of language areas of a patient prior to surgery on a brain tumor. Thus, this film provides students with an understanding of the methodology and power of current research in neuroscience.With Susan Bookheimer, Ph.D.
