Face to Face

Friend or foe? Happy or angry? Male or female? Being able to quickly and accurately answer these questions when someone approaches is undoubtedly important for social interaction today. During our evolutionary history it may have meant the difference between life and death. Eye tracking studies show that when considering a face adults focus mainly on the area at the bridge of the nose, just below the eyes (red zone, bottom row) despite the fact that scanning around the eyes, nose and mouth would actually provide more useful information (red/yellow areas, upper row). This strategy may have evolved as a short cut, enabling the brain to make a rapid, educated guess about identity, emotion or gender. People with certain conditions, such as autism, struggle to recognise facial cues. This research may help to understand their perspective and improve treatment in the future.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
