1. vision wavelength= amplitude = purity =

   diff frequencies (colors) brightness- one factor saturation/vividness

2. rods

   peripheral, greater #, outlines NIGHT

3. cones

   center (fovea), color, detail DAY

4. trandsuction anatomical pathway

   retina -> nt's -> bipolar cells -> ganglion cells -> optic disk -> optic nerve -> brain.

5. visual primary cortex where?

   occipital lobe

6. colateral stimulus

   inside of eyes, crosses to other hemisphere

7. ipsilateral

   outside portion of visual stimulus goes to same hemisphere

8. parietal lobe

   where? pathway cerebral cortex

9. temporal lobe

   what? pathway cerebral lobe

10. theories of eye operation

    COLOR VISION: trichromatic theory (cones and rods level) works with opponent process theory (Neural level) Form Perception: bottom up + top down processing (gestalt principles, perceptual hypothesis, etc) Depth perception: monocular and binocular cues Pictoral cues: cues about depth in flat picture

11. monocular cues

    height in plane , linear perspective, texture gradient, interposition, light + shadow

12. binocular cues

    retinal disparity (25 feet)

13. auditory stimulus wavelength = amplitude = purity =

    sound waves pitch loudness timbre (quality)

14. auditory receptor

    hairs on bm -> basilar membrane -> cochlea

15. primary auditory cortex

    temporal lobes

16. theories of function

    Pitch theory place theory + frequency theory (moves at once, wake peaks at specific place, rate b membrane shakes due to pitch) Auditory Localization

17. primary Gustatory cortex

    insular cortex (frontal lobe)

18. primary olfactory cortex

    olfactry bulb: DOES NOT GET ROUTED THROUGH THALAMUS FIRST, LIKE ALL OTHERS.
