WebGranule cells. Granule cells are anaxonic and send peripheral dendrites into the EPL, where they bear large spine-like protrusions, gemmules, and central processes with spines into the GCL. Gemmules contact mainly secondary dendrites of mitral/tufted cells and make reciprocal pairs of synapses (Figures 5 and 6 ). WebFeb 26, 2013 · The cerebellum is critical for coordinating movement and for learning sensorimotor relationships (Ito, 2006, 2008).Sensory and motor-related afference to the cerebellum is largely conveyed by mossy fiber inputs to granule cells, which notably constitute over half the neurons of the mammalian brain (De Schutter and Bjaalie, 2001; …
