Mechanisms underlying the control and generalization of sensorimotor learning

To cope with a continuously changing environment, the human brain has evolved an impressive ability to flexibly adjust, from one movement to the next, its motor commands. Such learning is a hallmark of any intelligent system and is central to human cognition and behaviour. Yet, the mechanisms that support sensorimotor learning and updating, and which allow acquired skills to be readily transferred to new contexts, remains poorly understood. The broad aims of the research program proposed here are to (1) better understand the mechanisms and strategies through which individuals learn sensorimotor tasks, (2) explore how this learning can be improved and better generalized, and (3) better understand the neural circuitry that supports sensorimotor learning and updating. The proposed research consists of three separate projects.
