| Cybernetics Approach to Perception & Action | |||||||||||||||
| The "Cybernetics Approach to Perception and Action" (CAPA) group was created to apply information theory, signal theory and advanced control system methods to understanding self-motion perception and action. One of the major goals of this group is a to get a deeper understanding of the processing self-motion information by considering the brain as a complex control system, which has sub-components that can be individually evaluated, but which may also be part of a larger system. ◘ Helicopter Control with Inertial and Visual Cues

Multisensory control of action When reaching for a target object, the afferent signals provided by different sensory channels are continuously processed to supervise the ongoing movement. If a discrepancy is detected between the predicted end-point of the movement and target location – e.g., motor error or unexpected perturbation –, the arm trajectory can be modulated online to preserve reaching accuracy. This online control constitutes a fundamental skill of our everyday motor repertoire.  Our aim is to understand how sensory channels like vision, proprioception, audition and the vestibular system are integrated to achieve motor control. We use basic paradigms in which a subject’s ability to react/respond to events occurring during the execution of goal-directed actions is assessed.
Different approaches are combined, which include psychophysics using virtual environments, body motion recording, muscles activation recording, and Transcranial Magnetic Stimulation.
