Intense activity activates proteins that help the brain (repair & grow) Supply & demand of atp: rate of atp has to be met by rate of supply. Control systems: to meet a desired output) from influences of feedback inputs) Feedback process where a system regulates itself by monitoring its own output. (able to adjust its performance. Feed-forward pathway in a control system that passes a command signal to control the output (separate.
