The literal definition of a fat head:

The brain is segregated into areas of gray and white, with the cerebral and
cerebellar cortices possessing a gray appearance and the brain stem,
cerebellar peduncles and spinal cord a white appearance. The white matter
has a high fat content and is readily visualized by magnetic resonance
imaging (MRI) or computerized tomography (CT) scanning.
