-- NCX: fast, NOT ATP-dependent
-- SERCA: slowest, ATP-dependent
-
-Quindi non comprendiamo anche il ristabilimento del Voltage, con altri Ioni entranti e uscenti, per ora tutto dipende da AP del SOMA.

-Abbiamo il caso di clearance nel contesto di un AP e non nel contesto di AP, per eliminare il Ca2+ fra le spike.

 Serve a dare la velocita' al trasporto di vesicles da RP a RRP. The biological meaning is that a synapse that has just been through a burst is primed for fast recovery — the molecular machinery for vesicle docking is already engaged, calcium-dependent priming factors are still elevated, and the system is in a ready state. A synapse that has been silent for several seconds has cooled down and replenishes slowly.

+- Ca+2 fullness che si puo' verificare alla fine di un AP
+- NOT ca2+ fullness che svuota piu' lentamente
+- da capire se serve veramente questa distinzione anche in bae alle tracce di Ca2+ che prendiamo in presynapse.
