Neurons in the human visual cortex that respond to faces  

A new study identifies the neurons in the human visual cortex that selectively respond to faces. The researchers showed that the neurons in the visual cortex (in the vicinity of the Fusiform Face Area) responded much more strongly to faces than to city landscapes or objects. In an additional experiment, the neurons exhibited face-selectivity to human and animal faces that appeared within a movie. The results provide unique insights into human brain functioning at the cellular level during face p
