Neural mechanisms underlying postural control.
Postural reflexes are evoked and controlled by a variety of sensory inputs. The vestibulo-spinal (VS) pathways carry sensory vestibular signals to widespread regions of the spinal cord where they interact with motor nuclei to produce reflexive movement. This laboratory studies the vestibulo-collic reflexes (VCR), which are an important subset of postural reflexes that avert potential neck injury by reorienting the head during perturbations of the body. These mechanisms are studied using a variety of electrophysiological techniques for relating the response properties of the vestibulospinal neurons to functional aspects of the behavior and to the muscular activity used to produce the behavior. The functional aspects of the behavior to a certain extent depend on the behavioral context in which the reflex was evoked. Newer studies will investigate whether and how the signals arising from the vestibulospinal pathways participate in modifying the performance of reflexes during different behavioral contexts. We seek to understand the signal processing carried out by the spinal pathways and to relate it to the motor activity used to produce the reflex by correlating simultaneously recorded electromyography of neck muscles with neural activity. The results of these studies are not only significant to our understanding of the sensory-motor control of head movements but are also globally applicable to the control of all vestibular postural reflexes because their mechanisms likely utilize similar neural processing strategies.
