Granule cell of the cerebellum
WebMar 20, 2024 · Classical theories suggest that granule cells in the cerebellum carry sensory and motor signals, enabling downstream Purkinje cells to sense fine contextual changes relating to movement. WebCerebellar granule cells originate from precursors located in the dorsal region of rhombomere one within the hindbrain of developing embryos. They undergo proliferation for an extensive period well into postnatal stages of development to form the major cell type of the cerebellum, the most populous structure within the mammalian brain.
