Qui comprendiamo:

- DENDRITIC-BRANCH: Dendritic Branch

## DENDRITIC-BRANCH: Container

**Simplified behaviors**:

— ms:

- Each active spine contributes VPost (EPSP) to VDB
- VDB decays passively each ms
  
— secs:

- nothing in the simplified model

— mins:

- nothing in the simplified model  
  (structural remodelling of spine neck geometry under LTP/LTD would live here if added later)

```Gen
Container: DENDRITIC-BRANCH

  include:
    BEH-POST.md

  expansion:
    - BEH-POST ( full: 50x, active: 0x, empty: 10x ) 
      # managed_by: BEH-EXH or BEH-INH from winnertakeall
      # developed_by: DEV-BD-BEH-POST-TUB from DEV-N

**Tubs:**

- **VPost**: e' l'integrazione degli EPSP della postsinapse

#### CheckVPost:Context

Contestualizziamo in maniera Fixed?

```Gen
context: CheckVPost
  contained_by: DENDRITIC-BRANCH

  in_context: Fixed
  rf: ( active: 60x )

  condition: (VPost fullness)
    out_context: VPostMax

  condition: (VPost mediumness)
    out_context: VPostMedium 

  condition: (VPost emptiness)
    out_context: VPostLow
```

##### VDBMax: Episode

```Gen
episode: VDBMax
  contained_by: DENDRITIC-BRANCH

  in_context: VPostMax
  rf: ( active: 2x )

 hypothesis: NOT (VDB full)
  action: [VDB increase]
  trace: 
```

##### VDBMed: Episode

```Gen
episode: VDBMed
  contained_by: DENDRITIC-BRANCH

  in_context: VPostMed
  rf: ( active: 2x )

 hypothesis: NOT (VDB full)
  action: [VDB increase]
  trace: 
```

##### VDBLow: Episode

```Gen
episode: VDBLow
  contained_by: DENDRITIC-BRANCH

  in_context: VPostLow
  rf: ( active: 2x )

 hypothesis: NOT (VDB full)
  action: [VDB increase]
  trace: 
```

#### VDBlearance: Episode

Qui facciamo il clearance del VDB. Lo facciamo in questo modo perche' abbiamo semplificato quello che succede fra BD e SOMA.

Qui posso aggiungere il flush, clearance veloce quando c'e' il bAP.

```Gen
episode: VDBClearance
  contained_by: DENDRITIC-BRANCH

  in_context: Fixed
  rf: ( active: 2x )

 hypothesis: NOT (VDB empty)
  action: [VDB decrease]
  trace: 
```
