What is it about?
Because the cerebellum is much more tightly folded than the cerebral cortex, it has never been fully reconstructed and unfolded. By scanning a preserved cerebellum at ultra-high magnetic fields, we showed its surface area has expanded even more than the surface area of the cerebral cortex when compared to monkeys.

Why is it important?
The unusual expansion of the human cerebellum may in part be responsible for characteristically human behaviors such as intricate tool-making, language, complex social interactions, and efficient abstract thought.
