Calcium contained or stored within neurons or extracellular calcium readily available for neurons to utilize for receptor binding, influx through channels, flux through transporters or pumps or for intracellular second messenger signaling is calcium in the nervous system.

Ca2+ and Ca2+ Signaling

The calcium ion (Ca2+) is a ubiquitous ion and second messenger found in all living organisms. Ca2+ facilitates cellular responses to external and internal stimuli and is critical for normal cellular function and survival. It regulates the activity of a large number of enzymes involved in a variety of physiological processes. In neurons, Ca2+ controls many cellular processes such as synaptic plasticity, neurotransmitter release, gene expression, differentiation, and cell fate. Ca2+signals activate specific cellular processes at different rates. For example, some processes such as synaptic vesicle...
