Qui riportiamo la struttura della espressione G e una descrizione di come leggerla (uno dei possibili modi):
- i possibili behavior della presynapsi sono espressi in due contesti. AP_ctx and NOT AP_ctx.
- i possibili behavior sono anche raggrupati in ms, sec e min, per facilitarne la verifica. Quello che conta sono gli RF specifici di ciascuno snipplet.

- 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.
