Neurons in the medial temporal lobe are selectively responsive to particular visual objects, but their activity is modulated by internal cognitive effects. Here it is shown that humans can regulate the activity of their MTL neurons to alter the outcome of the contest between external images and their internal representation. Using a brain–machine interface, subjects looked at a hybrid superposition of two images and had to enhance one image at the expense of the other, using cognitive strategies such as attention and imagery.
