+- All'arrivo di un AP dal SOMA, si aprono i canali ionici VGCC. Il numero di VGCC e' soggetto a tuning a medi termine.
+- i VGCC fanno entrare ioni Ca2+ nella Presynapse, in base a:
+  - quanto Ca2+ e' gia' presente (proxy per CDI)
+  - alla concentrazione di eCB (che arriva dalla Postsynapse e tende a limitare l'ingresso di Ca2+ per limitare indirettamente il rilascio di NT)
+  - alla concentrazione di NT (proxy per mGlur) 
+- il rilascio di NT avviene in base alla concetrazione di Ca2+ e la concentrazione di Rrp (readily release pool)

 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.
