Parts of the brain used in recognising familiar faces |
Brain
showing the visual cortex
|
|
|
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.

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.
