Topic: pontine nuclei

High-dimensional neural representations are observed in many brain areas and are believed to be a powerful substrate for flexible computation. Theories have suggested that the vertebrate cerebellum and other cerebellum-like structures produce such high-dimensional representations by expanding their input into a vast layer of granule-like cells. Signals are typically routed to such expanded representations by anatomical “bottlenecks”: in the mammalian cortico-cerebellar pathway, input from across the cortex converges in the pontine nuclei, from which roughly half of the mossy fiber input to gra
