Anatomical terms of neuroanatomy

The posterior lobe of cerebellum or neocerebellum, is the portion of the cerebellum below the primary fissure.[1]

It is sometimes called the neocerebellum[2] since phylogenetically it is the newest part of the cerebellum. It plays an important role in fine motor coordination, specifically in the inhibition of involuntary movement via inhibitory neurotransmitters, especially GABA.[2]

The posterior lobe receives input mainly from the brainstem (i.e., reticular formation and inferior olivary nucleus) and cerebral cortex.[3]

It also has activation linked to happiness.[4]
