We stand without falling by using silent senses from muscles and the balance organs of the inner ear to unconsciously detect and control our movements. Since the leg muscles provide both the force and the sense, and critically rely on good circulation, they are vitally important. I propose to study how these sensory and muscle functions are used to control balance, posture and stepping reflexes, making it easier to identify older people who will fall and design new preventative strategies.

Summary
Cells in some regions of the brain, collectively known as the sensorimotor cortex, control our capacity to purposefully move the arms and hands. Damage to these regions in adults causes severe deficits. However, rehabilitative training can restore some control over the muscles. To understand how the brain circuits change to compensate for injury, and what effect rehabilitation may have on these changes, I will study cellular alterations in the movement control pathways in the cerebral cortex.
