Perception is the process by which the brain. organizes and interprets sensory information. 4. The absolute threshold is the minimum stimulation needed to detect a stimulus 50 percent of the time. 9. Sensory adaptation refers to the decreased sensitivity that occurs with continued exposure to an unchanging stimulus. 10. In the study of sensation, transduction refers to the process by which receptor cells in the eye, ear, skin, and nose convert environmental stimuli into neural impulses. 17. The retina is the light-sensitive, multilayered inner surface of the eye that contains the rods and cones, as well as neurons that form the beginning of the optic nerve. 18.

The rods have poor sensitivity, detect black and white, and function
