The hypothalamus is less than two centimeter in diameter, and it is belittled by its name (which sounds as if it were a minor appendix of the thalamus).
The cerebellum may contain more than a thousand times the number of neurons, and it is of supreme importance for anything that has to do with timing,but appropriate timing is a self-understood property of a functioning organism.
