Calcium (Ca²⁺) is the essential element released from bone to bloodstream in humans. In neuroscience, calcium (Ca²⁺) plays fundamental and diversified roles. As ubiquitous second messenger in multiple signaling pathways, it has been proved that Ca²⁺ participates in multiple biological functions. The cytosolic Ca²⁺ concentration is regulated by the opening of the plasma membrane and subcellular Ca²⁺ sensitive channels and ultimately leads to the flexibility of Ca²⁺ signaling.
