Air Flow Sensing in Bats

Abstract
Sensing is fundamental to the control of movement:  From simple behaviors such as grasping, to complex motor sequences such as speech production, sensing guides action. Although sensorimotor feedback control lies at the core of most animal behaviors, the underlying neural mechanisms are poorly understood, particularly in complex mammalian systems. Bat flight, powered by a hand-wing, presents a valuable model to investigate the mechanisms of sensing and action. Specifically, microscopic hairs embedded in the membrane of the bat’s hand-wing serve as airflow sensors, which respond preferentially to reverse airflow, suggesting that wing hairs monitor signals to prevent stall and regulate flow separation.
