NCAN Seminar Series

Speaker: Lena H. Ting, Ph.D.
Title: Cortical activity during reactive balance reflect perceptual, cognitive, and motor function in health, aging, and disease
Time: April 29, 11 AM EST

Dr. Ting is a Professor and the McCamish Distinguished Chair in Biomedical Engineering at in the Coulter Department of Biomedical Engineering, at Georgia Tech and Emory and a Professor in Rehabilitation Medicine in the Division of Physical Therapy at Emory University. Dr. Ting directs the Neuromechanical Laboratory at Emory, focusing on complex, whole body movements such as walking and balance in healthy and neurologically impaired individuals, and skilled movements involved in dance and sport. Her work is highly interdisciplinary, drawing from neuroscience, biomechanics, rehabilitation, computation, robotics, and physiology. Her lab has developed several computational methods to characterize and understand individual differences in movement and movement control, and how these change in neurological disorders, as well as with rehabilitation and training. Dr. Ting also co-directs the Georgia Tech and Emory Neural Engineering Center and an NIH T32 in Computational Neural Engineering. Dr. Ting is a Fellow of the American Institute of Medical and Biological Engineers (2016), she was awarded the Arthur C. Guyton Award for Excellence in Integrative Physiology by the American Physiological Society (2007), the Atlanta Business Chronicles, Healthcare Hero Award (2018) and several teaching and mentoring awards from Georgia Tech and Emory University.

Engagement of cortical resources in balance control is an indicator of fall risk in older adults where people cannot “walk and talk” at the same time. However, there are few direct measures of cortical activity during balance control, and their relationship to balance and other brain functions is unclear. Evidence shows that various electroencephalography (EEG) measures of cortical activity during reactive balance recovery are associated with individual differences across perceptual, cognitive, and motor domains. Specifically, her focus is on the N1 evoked response in balance perturbations, as well as beta oscillations prior to and in response to perturbations. Direct measures of cortical activity can stratify healthy young and older individuals without clinically identifiable impairment. Further, relationships between cortical activity and function differ as a function of age, balance ability, and neurological disorders such as stroke and Parkinson’s disease. The intersections across perceptual, cognitive, and motor domains may help identify complex mechanisms underlying balance function. Her findings suggest that direct measures of hierarchical balance control mechanisms could enable development of mechanistic, precision-medicine efforts aimed at fall prevention.

Speaker: Gelsy Torres-Oviedo, Ph.D.
Title: Neural Mechanisms of Locomotor Adaptation and Savings Across the Lifespan
Time: May 27, 11 AM EST

Dr. Gelsy Torres-Oviedo is an accomplished researcher and educator specializing in locomotor learning, motor control, and neurorehabilitation. She is currently an Associate Professor in the Department of Bioengineering at the University of Pittsburgh and Co-director of both the MS2PhD BRIDGE Fellowship and the Program in Neural Computation, a joint initiative between Carnegie Mellon University and the University of Pittsburgh. Dr. Torres-Oviedo earned her B.S. in Physics from the University of Texas at Austin, a Ph.D. in Biomedical Engineering from Georgia Tech-Emory University, and completed postdoctoral training in Neuroscience at Johns Hopkins University. Dr. Torres-Oviedo has received numerous honors, including the NSF CAREER Award and the Early Career Award from the Society for Neural Control of Movement. She has led multiple NIH- and NSF-funded projects. Through her leadership roles and interdisciplinary collaborations, Dr. Torres-Oviedo continues to advance knowledge in motor learning and rehabilitation, aiming to improve mobility and independence for older adults and individuals with movement disorders.
