Evolutionary conservation of the cerebellar circuitry in zebrafish. Schematic drawing of the circuitry in the cerebellum of zebrafish (a) compared to that in mouse (b). Thick lines indicate direct connections of the Purkinje cells. Green arrows indicate intracerebellar excitatory input connections, while magenta arrows symbolize intracerebellar inhibitory input. Extracerebellar input or output instead is shown by dashed arrows with excitatory connections shown in green and inhibitory ones marked in magenta. BC basket cells, Cb cerebellum, CF climbing fibers, DCN deep cerebellar nuclei, EC eurydendroid cells, GC granule cells, GCL granule cell layer, GoC Golgi cells, MF mossy fibers, MOL molecular layer, PC Purkinje cells, PCL Purkinje cell layer, PCN precerebellar nuclei, StC stellate cells, WT withe matter. Information mostly based on: [72, 83]. Additional literature was also taken into consideration (see text)
