Q

gestalt-pragnanz principle

A

reality is organized to the simplest forms like the olympic circles

32
Q

gestalt-proximity principle

A

objects closer to one another are grouped together

33
Q

gestalt-continuity principle

A

lines are following the most continuous smoothest path

34
Q

gestalt-closure principle

A

objects grouped together are seen as a whole picture rather than individual items

35
Q

conjuctiva of the eye

A

epithelial outer lining of the eye

36
Q

cornea

A

transparent thick sheet of tissue under the conjunctiva

bends the light

37
Q

aqueous humor

A

salty water filling the anterior chamber of the eye

38
Q

anterior chamber

A

water chamber of the eye

39
Q

pupil

A

biconvex lenses and iris make it up
it is a hole that
can change shape based on the proximity and light because or iris muscle

40
Q

pupil contracts in __ proximity and __ light

A

close

high

41
Q

pupil relaxes in __ proximity and __ light

42
Q

lens

A

biconvex

bends the light so it goes to the back of the eye ball

43
Q

ciliary body

A

secretes the aqueous humor

made up of suspensory ligaments and ciliary muscle

44
Q

posterior chamber

A

area behind ciliary muscle filled with aqueous humor

45
Q

iris

A

part of he eye that is colored

are muscles that contract and expand to control the size of the pupil

46
Q

vitreous chamber

A

filled with vitreous humor that is like the aqueous humor with some added protein that makes it a little jelly-like
provide structure to the eye

47
Q

retina

A

it is red colored
entire back of the eye-ball
composed of photoreceptors
made up of macula and fovea

48
Q

macula of retina

A

rich in cones

49
Q

fovea of the retina

A

completely covered in the cones NO RODS

50
Q

optic nerve

A

nerve getting signal from the retina sending the message to the brain

51
Q

choroid

A

pigmented black in humans
no pigmentation in animals so it can reflect light-enhancing night vision
network of blood vessels nourishes cells of the eye

52
Q

sclera

A

whites of the eye

53
Q

cones

A

help you see in more details

54
Q

what is light?

A

electromagnetic wave part of a large spectrum

400-700nm

55
Q

light enters pupil and goes to the retina which contains in __ and __

A

rods and cones

56
Q

rods are responsible for __

A

sensing ligth

57
Q

cones are responsible for __

A

sensing colors

58
Q

rods in the dark are turned __

59
Q

rods in the light are turned __

60
Q

when the rod is off it activates __ , which then activates __ which enters the __ to reach the __

A

bipolar cell
ganglion
optic nerve
brain

61
Q

3 types of cones

A

red, blue, green

62
Q

almost all cones are located in the __ of the __

A

fovea of the retina

63
Q

main protein in rods

64
Q

what turns off the rod cells

A

the closing of Na channels in rods which hyper-polarizes the cell

65
Q

what is a photoreceptor

A

a cell that can convert light into a neuronal signal

66
Q 
cones detect colors
color sensitivity of our cones 
red\_\_
green \_\_
blue\_\_
67
Q

rods have __ recovery time

cones have __ recovery time

68
Q

in the blind spot

A

there are no rods or cones

69
Q

rods can be found

A

retina/outside of the fovea on its periphery

70
Q

cones can be found

A

retina/in the fovea

71
Q

optic chiasm

A

where the eft and the right optic nerve converge in the brain

72
Q

left visual image is processed in the __ side of the brain

73
Q

right visual image is processed in the __ side of the brain

74
Q

parvo pathway

A

spatial recognition
high spatial resolution-used for static objects
low temporal resolution- can’t detect details of a moving object

75
Q

trichromatic theory

A

serves as a feature detection devise which encompasses the

color, parvo and magno pathway

76
Q

parallel processing

A

seeing colors, movement and shape of an image all at the same time
simultaneous visual processing

77
Q

magno pathway

A

high temporal resolution- can see details about moving objects
low spatial resolution- can’t see details about localized objects
