Learning Activity Unit 2 Study Guide: Senses and Perception Senses 1. List the five senses and the area of the brain where each is processed. a. Smell- receptor neurons in the frontal lobe b. Taste- brain stem c. Touch- parietal lobe d. Sight- occipital lobe e. Hearing- temporal lobe 2. Explain the purpose of the sensory organs and how they send messages to the brain. • Sensory organs function as receptors and receive the stimuli, then it sends nerve impulses to the related effectors.
