The flashcards below were created by user kimkrak on FreezingBlue Flashcards. What would you like to do?


  1. sensation
    process where you detect physical energy from environment and encode it into neural signals
  2. perception
    • process enabling you to recognize meaningful objects and events
    • effected by memory, motivation, emotion, & culture
  3. ROY G BIV combined makes
    white light
  4. the color we percieve within the visible light section is based on
    • light intensity &
    • wavelength of light ( red has longest wavelength)
  5. bLACK ____ OTHER COLORS WHILE WHITE _____ THEM
    bLACK ABSORBS OTHER COLORS WHILE WHITE REFLECTS THEM
  6. THE CORNEA
    protects the eye
  7. after cornea light travles through
    aqueous humor  which maintains eye pressure
  8. after aqueous humor lioght goes through
    pupil which is controlled by iris
  9. after the pupil light goes to
    lens which focuses the light
  10. after lens the ligth goes through the
    vitreous humor which maintains eye shape
  11. what does the retina do
    proocess the image and turns them into neural impulses and send to optic nerve where image is turned upright
  12. transductoin
    translation of incoming stimuli into neural signals
  13. transdutction occurs in the eyes at the
    retine
  14. photoreceptors
    capture light rays and convert them into neural impulses
  15. cones
    densly packed at fovea(center of macula)
  16. cone functon best in
    • bright light
    • c- color, clarity, & central vison
  17. rods
    hot rods come out at night
  18. rods spred throughout
    • peripheral retina
    • peripheral vision relies on rods and is seen in black and white
  19. dark adaption
    when light suddenly becomes dark
  20. what activites when rods and cones fire
    bipolar cells
  21. when enough bipolar cells fire what becomes activated
    ganglion cells
  22. what do the axons of the ganglion cells jion to form
    optic nerve
  23. impulses are sent to place in thalalmus called the
    lateral geniculate nucleus (LGN)
  24. after the LGN its sent to the
    visual cortex in the occipital lobe
  25. in the visual cortex it encounters
    feautre detectors, whcih oricess info like color &b contours
  26. optic chiasm
    where optic nerves cross
  27. parrallel processing
    simutaneous processing of stimuli by featier detectors
  28. hubel & wiesel
    showed fature detectors respond to visual igns in the promary visual cortex
