Schematic of the differential expression of the CBPs in the adult zebrafish spinal cord. a Motoneuron pools that contribute to the generation of fast movements (fast swimming and escape) utilize both CR and PV as calcium buffer proteins. b The progenitor cells/stem cells utilize CB to buffer their intracellular calcium. The mature neurons mainly use CR and PV as a calcium binding proteins. This suggests that CB can serve as anatomical marker to identify the developmental events that generate neurons in the adult zebrafish spinal cord
