Stimulus–response models, tolerance limits and negative feedback

What this note covers

1. Homeostasis regulates internal variables within limits
2. Negative feedback opposes the initiating deviation
3. Tolerance curves connect performance to environmental range
4. Conformers and regulators use different response strategies
5. Investigations separate response, cause and limitation
6. Homeostatic capacity has costs and failure points
