Modulation of Movement by the Cerebellum - Circuits within the Cerebellum

4 important questions on Modulation of Movement by the Cerebellum - Circuits within the Cerebellum

What cells are the ultimate destination for afferent pathways from cortex to cerebellum?

Purkinje cells

What path does information from the cortex needs to walk to reach the Purkinje cells in the cerebellum? 6 steps

From cortex (1) information travels towards the pontine nuclei (2). From here mossy fibers (axons of pontine nuclei) cross the midline (3) to synapse at he granule cells (4). Axons arise from here and form T-shaped braches called parallel fibers (5). The parallel fibers ultimately synaps with the dendrites of Purkinje cells (6).

What information do climbing fibers provide to the Purkinje cells?

Climbing fibers produce long-term changes in the cerebellar output, which can be learned by motor error
