I try to understand the neural mechanisms underlying control of balance and how it is integrated with other tasks, like locomotion. We perturb the sensorimotor loop of balance control by inducing illusory falls using Galvanic vestibular stimulation and visual scene motions and introduce obstacles as additional subtasks. Observing reactions to illusory falls allows us to infer how the neural controller maps sensory information to motor commands. Based on experimental data, we develop process models of the sensorimotor control loop that facilitate deeper understanding of the neural dynamics.
