Stimulus-Response

1. A stimulus is a change in the environment (either external or internal) that is detected by a receptor.
2. Receptors transform environmental stimuli into electrical nerve impulses.
3. These impulses are then transmitted via neurons to the central nervous system where decision-making occurs.
