Across
- 2. The light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information
- 3. The nerve that carries neural impulses from the eye to the brain
- 7. the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
- 8. The focusing of conscious awareness on a particular stimulus
- 9. Information processing guided by higher-level mental processes, as when we construct perceptions drawing in on our experience and expectations
- 12. Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
- 14. Retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions
- 15. The transparent structure behind the pupil that changes shape to help focus images on the retina
Down
- 1. Failing to notice visible objects when our attention is elsewhere
- 4. Retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond
- 5. The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
- 6. A ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening
- 10. Where light enters; protects the eye and bends light to provide focus
- 11. The central focal point in the retina, around which the eye's cones cluster
- 13. The adjustable opening in the center of the eye through which light enters
