There is definitely more than meets the eye where faces are concerned. Researchers are investigating the process of facial recognition, seeking to understand the complexity of what is actually taking place in the brain when one person looks at another. The studies target people who display an inability to recognize faces, a condition long known as prosopagnosia. The research is aimed at trying to understand the neural basis of the condition while also make inferences about what is going wrong in terms of information processing -- where in the stages that our brains go through to recognize a face is the system breaking down. A new paper details the most recent experimental results.
