Parts of the brain used in recognising familiar faces
When you recognize a familiar face the parts of the brain highlighted in orange on this functional magnetic resonance image (fMRI) light up. In this case 'lighting up' means there is increased blood flow to the areas that are working hardest. Functional MRI allows these regions to be visualized. They can then be superimposed onto a 3D reconstruction of the brain to get a precise picture of the location of those regions

Brain showing the visual cortex
The visual cortex is highlighted in this brain image created using functional magnetic resonance imaging. The surface of the brain has been expanded so the parts that are normally hidden away down the folds are 'blown out' and are shown as darker areas. The visual cortex is the part of the brain that is active when you look at something.
