Envisage walking into a room of people, or wandering down a busy sidewalk, watching a TV program-and not knowing who anyone is because you can't recognize faces. Unfortunately, for a small minority of people recovering from a tragic illness or accident, this is the world they live in. Thankfully, scientists are now much closer to understanding how facial recognition works, with significance for possible future remedies. In the meanwhile, their work is enjoying immediate application in law enforcement. As infants, we can recognize our mothers within hours of birth. In fact, we can recognize the composition of our mother's face well before we can recognize her body shape. It's fascinating how the brain can carry out such an elaborate function at such a young age, especially since we don't learn to walk and talk until we are over a year old. By the time we are adults, we have the ability to distinguish around 100,000 faces. How can we remember so many faces when many of us find it difficult to recollect something as simple as a phone number? The exact process is not yet fully understood, but research around the world has begun to pinpoint the particular areas of the brain and processes necessary for facial recognition. Researchers at the Massachusetts Institute of Technology believe that they have identified a specific area of the brain called the fusiform face area (FFA), which is used only for facial recognition. This means that recognition of familiar objects, such as our clothes or cars, is summoned from elsewhere in the brain. Researchers also have found that the brain needs to see the whole face for recognition to take place. Previously, it had been thought that we only needed to see certain facial features. Meanwhile, research at University College London has found that facial recognition is not a single process, but instead involves three sequential steps. The first step appears to be an analysis of the physical features of a person's face, which is similar to how we scan the bar codes on our groceries. In the next step, the brain decides whether the face we are looking at is already known or unknown to us. And finally, the brain furnishes the information we have collected about the person whose face we are looking at.
