Human brain. Coloured coronal magnetic resonance imaging (MRI) scan through the brain of a 30-year-old man. This is a T2-weighted scan. The scan has passed vertically through the head, as seen from the front, at the level of the ears. The scan shows the normal brain structures, including parts of the lateral ventricles (white, centre) and the folds of the cerebrum. Below the brain, on either side of the head, are the structures of the inner ear.
