The "Sub-Optimal" State. The machinery is working, but it's held back by partial limitations. This covers cases where the signal is steady but the "piston" isn't firing at full speed, or where a high vacancy in the RRP (nearEmpty) forces a low signal to work a bit harder.

The "High Performance" State. Multiple systems are optimized, but one is still at a "Medium" level. This represents an active synapse that hasn't reached its absolute peak because either the supply is only 50% or the RRP isn't empty enough to create that "maximal vacuum" pull.

#### Refill RP from Glutamine
|
||||
|

How RP is replenished
|
||||
This happens in the minutes loop, once per minute, via the glutamine shuttle from the astrocyte. It is a two-step process across two cells.
|
||||
|
||||
Step 1 — astrocyte side
|
||||
@@ -556,27 +556,6 @@ Step 2 — presynapse side
|
||||
|
||||
The glutamine crosses into the presynapse, where glutaminase converts it back into glutamate. That glutamate is immediately repackaged into vesicles and added to N_RP:
|
||||
|
||||
N_RP = min(Max_RP, N_RP + refill_RP)
|
||||
|
||||
The ceiling guard `min(Max_RP, ...)` prevents N_RP from exceeding its physical maximum.

**The full chain from release to re-availability**:
|
||||
|
||||
ms: NT released from RRP → N_RRP falls
|
||||
→ NT_cleft rises
|
||||
→ NT_released_this_window accumulates
|
||||
|
||||
seconds: EAATs clear NT_cleft → glutamate enters astrocyte
|
||||
Tr_Ca gates speed → N_RP moves into N_RRP
|
||||
→ (partially restores what was just depleted)
|
||||
|
||||
mins: glutamate → glutamine → Glutamine_pool filled
|
||||
glutamine → N_RP → reserve restocked for next seconds cycle

**The asymmetry that makes depletion possible**:
|
||||
|
||||
The chain reveals why sustained high-frequency firing eventually depletes the synapse even with all replenishment mechanisms running.
