Cerebellum
-
15% volume
-
69 billion neurons (most of the neurons!)
- Cerebrum (16B) + Cerebellum (69B) = 99% of total # neurons
-
Cerebellar hypoplasia
- Small cerebellum → abnormal motility
- ⇒ cerebellum — movement?
-
Cerebellum-deficit mouse
⇒ Coordination impairment of walking legs
-
King et al. Nature Neurosci, 2019
- Diverse functions are mapped into a cerebellum
-
⇒ Cerebellum may be highly related to high-level cognitive functions
- Autism — cerebellum (almost tobacco — lung cancer)
- Autism patients often show movement problems
