Across
- 4. very light sensitive photoreceptors found in the periphery
- 6. photoreceptors sensitive to different wavelengths and color
- 7. a rod or cone for example
- 8. environmental stimuli coming in through the senses
- 11. network of cell that respond to light energy
- 13. small area with only cone receptors; high acuity
- 15. our final interpretation of environmental stimuli
- 17. when multiple rods add their excitatory responses together
- 18. inverted relationship with threshold, one goes up, the other goes down
Down
- 1. process of lens fine tuning the focus of light onto the retina
- 2. regulated the amount of light passing through the pupil
- 3. ratio of receptors to ganglion cells in an area of the retina
- 5. changes shape to focus light for close and far vision
- 6. light passes through and this does 80% of light focus
- 9. in vision, the height of the light wave
- 10. we perceive color depending on this part of the lightwave
- 12. the amount of energy needed for an action potential
- 14. sharp, clear vision
- 16. opening where light passes into the eye
