(1979) who\u0026nbsp;hypothesized that\u0026nbsp;a single \u0026lsquo;super-ordinate\u0026rsquo; controller is recruited during bilateral tasks. Given\u0026nbsp;evidence of\u0026nbsp;hemispheric lateralization of motor control and resulting\u0026nbsp;significant interlimb differences in intralimb\u0026nbsp;coordination (Sainburg et al.,\u0026nbsp;Dynamic Dominance Hypthesis), it is\u0026nbsp;interesting to further our understanding of interplay between these two\u0026nbsp;mechanisms of neural control of movement. Does a single \u0026lsquo;super-ordinate\u0026rsquo; controller\u0026nbsp;take over during bimanual coordination changing\u0026nbsp;intralimb coordination of one\u0026nbsp;or both arms? During this talk, I will present evidence suggesting individual\u0026nbsp;control of each arm during bimanual\u0026nbsp;coordination, i.e. no coupling. Namely, interlimb\u0026nbsp;differences do persist in bimanual movements coordination and each limb\u0026nbsp;cooperates in\u0026nbsp;compensating task errors, thus stabilizing task performance, i.e.\u0026nbsp;synergy. Furthermore, these synergies can be modified fairly rapidly, even in\u0026nbsp;mild stroke patients whose bimanual coordination also reveals evidence that predictive\u0026nbsp;mechanisms of bimanual coordination depend on the\u0026nbsp;left hemisphere, consistently\u0026nbsp;with Dynamic Dominance Hypothesis.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Cstrong\u003EAbout the Speaker\u003C\/strong\u003E\u003Cbr \/\u003E\r\nDr. Andrzej Przybyla (Dre) is a new Associate Professor in the\u0026nbsp;Department of Physical Therapy at the University of North Georgia. He completed his PhD and the first postdoctoral\u0026nbsp;experience in spine biomechanics at the University of Bristol, U.K. (2000-06), under the supervision of Drs. Michael Adams and\u0026nbsp;Patricia Dolan. Following this, he joined Dr. Robert Sainburg\u0026rsquo;s laboratory at the Penn State University (2006-15) focusing his research on hemispheric lateralization of motor functions, i.e. bimanual coordination, motor\u0026nbsp;decisions, stroke rehabilitation. He spent one year (2015-16) in the School of Sports and Exercises Sciences\u0026nbsp;at the Liverpool John Moores University, U.K., working on clinical gait biomechanics\u0026nbsp;and motor behavior. His research focuses on neural mechanisms of movement control and motor\u0026nbsp;decision making with strong emphasis in applications to motor adaptation and learning, i.e. physical therapy, athletic\u0026nbsp;training, aging.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EPhysiology Brownbag Seminars\u003C\/strong\u003E\u003Cbr \/\u003E\r\nThe Physiology Group in the School of Biological Sciences hosts Brownbag Lunchtime Seminars twice a month on Wednesdays at noon in room 1253 of the Applied Physiology Building located at 555 14th Street NW, Atlanta, GA 30318.
