Zakaryah Abdulkarim

Research

One of the fundamental ways in which we interact with our surroundings is through movement. However, in order to move our body, we must have a sense of what this body is made up of, what belongs to us and what does not (i.e., body ownership). Zakaryah's research focuses on the neural processes that bring these two phenomena together, the feeling of ownership and voluntary action.
