Andrew B. Schwartz Bio


Dr. Schwartz received his Ph.D. from the Department of Physiology at the University of Minnesota in 1984. His graduate program emphasized motor neurophysiology with a thesis that examined the activity of the deep cerebellar nuclei during cat locomotion. He was awarded the Bacanner Prize for this research. Dr. Schwartz then went on to a postdoctoral fellowship at the Johns Hopkins School of Medicine where he worked with Dr. Apostolos Georgopoulos, who was developing the concept of directional tuning and population-based movement representation. While there, Schwartz was instrumental in developing the basis for three-dimensional trajectory representation in the motor cortex.

In 1988, Dr. Schwartz began his independent research career at the Barrow Neurological Institute in Phoenix. There, he developed a paradigm to explore the continuous cortical signals generated throughout volitional arm movements. This was done using monkeys trained to draw shapes while recording single-cell activity from their motor cortices. He found that these trajectories were represented continuously in the cortical activity and contained many of the kinematic invariants of natural movement.

Using this ability to capture a high fidelity representation of movement intention from the motor cortex, Schwartz teamed up with engineering colleagues at Arizona State University to develop cortical neural prosthetics based on the ability to record populations of single-cell activity with chronic electrode arrays. The work has progressed to the point that monkeys can now use these recorded signals to control motorized arm prostheses to reach out grasp a piece of food and return it to the mouth.

Schwartz moved from the Barrow Neurological Institute to the Neurosciences Institute in San Diego in 1995 and then to the University of Pittsburgh in 2002. In addition to the prosthetics work, he has continued to utilize the neural trajectory representation to better understand the transformation from intended to actual movement using motor illusions in a virtual reality environment. Presently he has identified cortical structures where there is a clear dichotomy in the perceived and actual representation and is working to identify the substrate for these differences.
