Dr. Nicholas G. "Nicho" Hatsopoulos, Ph.D. Dr. Hatsopoulos is currently an Associate Professor at the University of Chicago. Dr. Hatsopoulos is also Chairman of the Computational Neuroscience graduate program. He is currently running a laboratory with five graduate students, two postdoctoral fellows, and several technicians which is funded in part by the National Institutes of Health. From January 1998 to December 2001, Dr. Hatsopoulos was an Assistant Professor of Research in the Department of Neuroscience at Brown University. Dr. Hatsopoulos completed two postdoctoral research fellowships, one in the Department of Neuroscience at Brown University and the other in the Computational Neuroscience Program at the California Institute of Technology. Dr. Hatsopoulos completed his B.A. in Physics from Williams College in 1984, his M.S. in Psychology in 1991 and his Ph.D. in Cognitive Science from Brown University in 1992. In 2001, he co-founded a company, Cyberkinetics Neurotechnology Systems, which is taking the basic scientific research he and his colleagues have conducted to develop neural prosthesis technology to assist people with severe motor disabilities. http://pondside.uchicago.edu/oba/faculty/Hatsopoulos/lab/

"A lot of patients that are motor-disabled might have partial sensory feedback," said Nicholas Hatsopoulos, PhD, Associate Professor and Chair of Computational Neuroscience at the University of Chicago. "That got us thinking that maybe we could use this natural form of feedback with wearable robots to provide that kind of feedback."
In the experiments, monkeys controlled a cursor without actively moving their arm via a device that translated activity in the primary motor cortex of their brain into cursor motion. While wearing a sleeve-like robotic exoskeleton that moved their arm in tandem with the cursor, the monkey's control of the cursor improved, hitting targets faster and via straighter paths than without the exoskeleton.
"We saw a 40 percent improvement in cursor control when the robotic exoskeleton passively moved the monkeys' arm," Hatsopoulos said.

Those troubles helped researchers realize the importance of proprioception feedback, Hatsopoulos said.
"In the early days when we were doing this, we didn't even consider sensory feedback as an important component of the system," Hatsopoulos said. "We really thought it was just one-way: signals were coming from the brain, and then out to control the limb. It's only more recently that the community has really realized that there is this loop with feedback coming back."
Reflecting this loop, the researchers on the new study also observed changes in the brain activity recorded from the monkeys when sensory feedback was added to the set-up. With proprioception feedback, the information in the cell firing patterns of the primary motor cortex contained more information than in trials with only visual feedback, Hatsopoulos said, reflecting an improved signal-to-noise ratio.
The improvement seen from adding proprioception feedback may inform the next generation of brain-machine interface devices, Hatsopoulos said. Already, scientists are developing different types of "wearable robots" to augment a person's natural abilities. Combining a decoder of cortical activity with a robotic exoskeleton for the arm or hand can serve a dual purpose: allowing a paralyzed subject to move the limb, while also providing sensory feedback.
To benefit from this solution, a paralyzed patient must have retained some residual sensory information from the limbs despite the loss of motor function -- a common occurrence, Hatsopoulos said, particularly in patients with ALS, locked-in syndrome, or incomplete spinal cord injury. For patients without both motor and sensory function, direct stimulation of sensory cortex may be able to simulate the sensation of limb movement. Further research in that direction is currently underway, Hatsopoulos said.
"I think all the components are there; there's nothing here that's holding us back conceptually," Hatsopoulos said.

NICHOLAS G. HATSOPOULOS, Ph.D. - Assistant Professor, University of Chicago. A founder of Cyberkinetics, Dr. Hatsopoulos has been an Assistant Professor in Organismal Biology and Anatomy at the University of Chicago since 2002. From 1998-2001, Dr. Hatsopoulos was an Assistant Professor of Research in the Department of Neuroscience at Brown University. Dr. Hatsopoulos has completed two postdoctoral research fellows, one in the Department of Neuroscience at Brown University and the other in the Computation Neuroscience Program at the California Institute of Technology. Currently his research focuses on the neural basis of motor control and learning and he is investigating what features of motor behavior are encoded and how this information is represented in the collective activity of neuronal ensembles in the motor cortex. Dr. Hatsopoulos completed his B.A. in Physics from Williams College in 1984, his M.S. in Psychology in 1991 and his Ph.D. in Cognitive Science from Brown University in 1992.
