The '''posterior lobe of cerebellum''' or '''neocerebellum''' is the portion of the [[Biology:Cerebellum|cerebellum]] below the [[Biology:Primary fissure of cerebellum|primary fissure]]. The posterior lobe is much larger than [[Biology:Anterior lobe of cerebellum|anterior lobe]]. The anterior lobe is separated from the posterior lobe by the primary fissure, and the posterolateral fissure separates [[Biology:Flocculonodular lobe|flocculonodular lobe]] from the posterior lobe.<ref>{{harv|Patestas|Gartner|2016|p=87}}</ref>

Sometimes, the posterior lobe of cerebellum is called the neocerebellum<ref name="urlThe Cerebellum">{{Cite web|url=http://www.csuchico.edu/~pmccaffrey/syllabi/CMSD%20320/362unit7.html |title=The Cerebellum }}</ref> 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 [[Biology:Neurotransmitter|neurotransmitter]]s, especially GABA.<ref name="urlThe Cerebellum" />

The posterior lobe receives input mainly from the brainstem (i.e., [[Biology:Reticular formation|reticular formation]] and inferior olivary nucleus) and cerebral cortex.<ref>{{cite book|last=Siegel|first=Allan Siegel, Hreday N.

It also has activation linked to happiness.<ref>{{cite journal |vauthors=Schienle A, Scharmüller W |date=August 2013 |title=Cerebellar activity and connectivity during the experience of disgust and happiness |journal=Neuroscience |volume=246 |pages=375–81 |pmid=23639880 |doi=10.1016/j.neuroscience.2013.04.048|s2cid=12832980 }}</ref>
