Animals (including humans) have a remarkable ability to effortlessly perform complex and fast movements. These movements are fundamentally constrained by the biophysics of the neurons and dynamics of the muscles involved. Yet, how these factors act together to limit our ability to make agile movements in health and disease have not been rigorously quantified. Furthermore, before we reach this limit, how the brain coordinates with muscles to execute movements at different speeds is not well understood. In the first part of my talk, I will focus on performance limitations of sensorimotor control. In the second part of my talk, I will focus on how the primate brain flexibly generates movements at different speeds.
