It then discusses the sequence of events involved in sensation, including stimulation of sensory receptors and transmission of signals to the brain. Finally, it briefly outlines several senses like vision, hearing, smell, and touch, and discusses perceptual processes.

3. Sequence of events that produce a sensation: 6. You respond! 5. Signal reaches the brain. 4. As a signal passes along sensory nerves to CNS, it is further coded. 3. Receptor sends out a coded electrochemical signal. 2. Stimulates a receptor cell in a sense organ (energy must be sufficient enough for receptor to respond). 1. Need a form of energy, either external or internal.
