  1. emmetropia
    normal vision
  2. accomodation
    the process by which the lens changes its shape, bulging for close objects, thinning for far ones.
  3. fundus
    the back surface of the eye
  4. unequal curving of one or more of the refractive surfaces of the eye, usually the cornea
  5. hyperopia
    light is focused behind the retina, near objects are out of focus
  6. cones work best in ___-topic conditions
  7. cells responsible for lateral inhibition
    horizontal cells
  8. what are center-surround receptive fields useful for?
    emphasizing object boundaries
  9. what kind of ganglion cells have small receptive fields, high acuity and work best in high luminance conditions?

    A) P-ganglion cell
    D) M-ganglion cell
    P ganglion cell
  10. P-ganglion cells are preceded by what kind of cell?
    midget bipolar cell
  11. M-ganglion cells are preceded by what kind of cell?
    diffuse bipolar cell
  12. cortical magnification in V1
    proportionally much more cortex is devoted to processing the fovea than the periphery.
