This page covers biological details of component Cerebellar Lateral Lobe. Region is part of aHuman target integrated biological model.

• Top-down path to region: Hindbrain Metencephalon -> Cerebellar Complex (LLC.HT.CRC) -> Cerebellum (LLC.HT.CR) -> Cerebellar Lateral Lobe (LLC.HT.CR.CC) (see Mind Maps)
• Type: cortex
• Brain area: Lower Brain - Locomotion Control Area
• Role: processor.automatic
• Function: planning movement that is about to occur, evaluating sensory information for action, handles intentions
• Notes to function: lateral zone of anterior and posterior lobes; dentate nucleus; receives input exclusively from cerebral cortex (especially parietal lobe) via pontine nuclei (forming cortico-ponto-cerebellar pathways), and sends output mainly to ventrolateral thalamus and to red nucleus; add skill to movements
