Coloured coronal MRI scans of a normal healthy brain. The scans start at the front of the head and move back through it. Initially the eyes are prominent, with the large black spaces of the sinuses between them. The symmetrical hemispheres of the brain are seen in the middle part of the clip, with the brainstem and upper spinal cord visible. In the last part of the clip, the cerebellum is seen below the two hemispheres.
