Regulation of functionality of a terminal by intracellular Mg2+. Schematic cartoon to illustrate the regulation of presynaptic functionality at a single terminal: ↑[Mg2+]i ⇒ ↑Mitochondria ⇒ ↑[ATP]i ⇒ ↑Axonal transport efficiency ⇒ ↑Ca2+-sensitivity-related proteins ⇒ ↑Ca2+ sensitivity ⇒ Terminal in functional state
