Brain–machine interfaces: See what you want to see
Leonie Welberg

Abstract
Visual images that we associate with a familiar concept activate neurons in the medial temporal lobe (MTL) that encode that concept. Now, Cerf, Koch, Fried and colleagues show that when multiple images are viewed simultaneously, humans can use conscious thought to regulate the activity of MTL neurons encoding different concepts, indicating that internal, cognitive processes can override neuronal activation induced by sensory input.
