| summary | When controlling goal-directed hand movements the human brain can encode in various reference frames the sensory signals related to the task. For example, kinaesthetic or visual encodings can be used independently for the available sensory information.
Experimental findings show that several factors can affect the choice of the sensory modalities selected to encode the task, but the neural mechanisms underlying this selection are still unclear. For instance, several studies on reaching movements have shown evidences for a visual encoding of tasks performed by using kinaesthetic feedback only, whilst other works have shown that such cross-modal reconstructions are not performed and that the task is performed in a body-centered reference frame.
Starting from these apparently contrasting findings, during the talk I will present the results of a set of experiments performed in my lab aimed at disentangling some of the factors affecting the sensory encoding. I will also introduce a unifying theory of sensorimotor control, based of statistical theory, able to reconcile these experimental results. |
