# homeostasis (regulation)

regulation whose target is the window's centre

- Computed level: L16 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: window  ·  Arena: emergent

## Emergence
**Emerges from:** [window](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-window.range), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [maintenance](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-maintenance.upkeep), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [centre](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-centre.location), [regulation](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-regulation.control)

**Through:** maintenance acts on parameter to resist drift toward wall, keeping value near center

**Novel properties:**
- targeted regulation toward center
- feedback-driven correction
- dynamic centring under drift

## Examples
- The human body maintains blood pH around 7.4 despite acidic or basic loads from diet and metabolism. *(biology)*
- The 2020 California power grid adjusted supply in real time to keep frequency at 60 Hz during heatwave demand surges. *(engineering)*
- The Federal Reserve raised interest rates seven times in 2022–2023 to curb inflation above its 2% target. *(economics)*
