[FRIAM] astrocyte mediated oxytocin

[glen]

Here's a LLM generated diagram of the feedback loop described here:

Astrocytes mediate a positive feedback loop for oxytocin
https://www.biorxiv.org/content/10.64898/2026.02.02.699227v1

It's not hard to register the feedback from Figure 4 I in the paper. But there's something about schematic diagrams that I like better than those cartoons my biology-oriented friends prefer. Just in case your markdown renderer handles mermaid differently, I've attached a screenshot from obsidian.

```mermaid
graph TD
     A[Oxytocin Release] --> B[Astrocytes in Hypothalamus]
     B -->|Sense Oxytocin| C[Astrocytes Activate]
     C -->|Prompt Neurons| D[Increased Oxytocin Production]
     D --> A
     C -->|Enhanced ALDH1A1 Expression| E[Retinoic Acid Synthesis]
     E -->|Mediates| D
```
