How is the brain able to remember and recognise hundreds of different faces?

How is the brain able to remember and recognise hundreds of different faces? Researchers at the California Institute of Technology have been able to locate six areas in the brains of humans and other primates that are responsible for identifying faces. These areas contain special types of neurons, called face cells, which are particularly active when we are looking at faces. The face-recognition process is surprisingly simple – by monitoring the electrical activity of just 205 face cells, scientists can reconstruct the face a monkey is seeing.
