Cerebellum

Central nervous system consists of brain, cerebellum, medulla oblongata and spinal cord.

The cerebellum requires continuous blood supply.

"On the other hand," Tam says, "we did find that when hydrocortisone and dexamethasone were given after the child was born, this was associated with decreased growth of cerebellum."

Although the cerebellum occupies just 10 per cent of the cranial cavity, it has more than half the brain’s neurons.
