个人简介

Understanding the brain mechanisms by which our mental events are transformed into goal-directed action remains one of the most significant challenges facing modern neuroscience. The aim of research in the Memory, Action and Perception laboratory (MAPlab) is to understand the human cognitive and neural bases of this transformation, in general, and how a variety of processes (e.g., decision-making, working memory, perception and learning) are used to guide the selection and control of our actions, in particular. Visit the lab web site to learn how we use a combination of techniques including behavioural measurements, functional brain imaging, neurostimulation and computational analysis tools to elucidate some of the cognitive transformations that support human goal-oriented behaviour.
