L'idea e' che la quantita' di RRP sia il driver principale. Gli NT liberati sono di piu' al crescere di RRP e CaMicro e di meno al crescere di NT. Gli NT nella sinapsi fanno da moderazione alla ulteriore liberazione di NT, ma non bloccano mai totalmente. NT suppression only matters when everything else is already at maximum — which is exactly the biological purpose: it prevents runaway release during peak activity, not during moderate activity. + +#### NTreleaseMaximum episodes + +```Gen +episode: NTreleaseMaximum + contained_by: BEH-PRE + + in_context: (Ca2MicroFull AND RRPFull) + rf: ( active: 6x ) # Maximum + + hypothesis: (NT empty) + action: [Rrp decrease, Nt increase, ATP decrease] + trace: None +``` + +#### NTreleaseHigh episodes + +```Gen +episode: NTreleaseHigh + contained_by: BEH-PRE + + in_context: (Ca2MicroFull AND RRPFull) + rf: ( active: 6x ) # High + + hypothesis: NOT (NT empty) # solo in questo caso NT modera! + action: [Rrp decrease, Nt increase, ATP decrease] + trace: None +``` + +#### NTreleaseMedium episodes + +```Gen +episode: NTreleaseMedium + contained_by: BEH-PRE + + in_context: (Ca2MicroFull AND RRPMedium) OR (Ca2MicroMedium AND RRPFull) + rf: ( active: 6x ) # Medium + + hypothesis: (NT empty) OR NOT (NT empty) # In tutti i casi + action: [Rrp decrease, Nt increase, ATP decrease] + trace: None +``` + +#### NTreleaseLow episodes + +```Gen +episode: NTreleaseLow + contained_by: BEH-PRE + + in_context: (Ca2MicroMedium AND RRPMedium) + rf: ( active: 6x ) # Low + + hypothesis: (NT empty) OR NOT (NT empty) # In tutti i casi + action: [Rrp decrease, Nt increase, ATP decrease] + trace: None +``` + +## BEH-PRE-VGCC: Container + +**Voltage-Controlled Gated Channels**: +Qui per ora non gestiamo l'evoluzione della depolarizzazione.
