HintAnswer
eye is too short, light focuses behind retina, farsightedness
visual area that responds to line features and contours
ganglion cell that receives input from diffuse bipolar cells and rods
contracted by iris to let more or less light in
Visual pathway
region w/out receptor cells where the optic nerve and blood vessels exit the eye, blind spot
2 theories required for color vision
photoreceptor:
photopigments in cons that are insensitive to light
around 50 rods connect to single diffuse bipolar cell
receptive fields: hyperpolarization in response to glutamate from photoreceptors
bending of light rays by the lens and cornea
specialized retinal cells that connect bipolar cells to ganglion cells
 
photopigment part:
interneurons of the retina that receive info from bipolar cells, axons from optic nerve
sensitivity and color depend on the...
acuity depends of the size of the...
focuses image on the retina
visual area that responds to basic geometric shapes and faces
transparent outer layer of eye whose curvature is fixed, it bends light rays and forms the image onto the retina
photopigment part:
where in axons of optic nerve terminate, has 6 layers
theory: combinations of the 3 opsins in cones represent a certain color
every cell in a ....... will respond to a specific orientation of a line as it is rotated 10-15 degrees
HintAnswer
interneurons of the retina that receive info from rods and cones
theory: 3 opsins in cones must be in ooposition of one another on receptive fields to be processed
central portion of retina packed w/most photoreceptors. mainly cones. sharpest vision
wave and particle that is light, electromagnetic radiation
eye is too long, light focuses in front of retina, nearsightedness
system that operates at low levels of light, involes rods
contracts pupil to let more or less light in
ganglion cell that receives input from midget bipolar cells and cons
receptive fields: depolarization in response to glutamate from photoreceptors
cells in V1 that process general orientation of lines at certain angles at certain motions
receptive surface inside back of eye, contains photoreceptors and other neuron cells
anatomy of retina (outer to inner)
nerve II, made of ganglion axons
region of occipital cortex where 90% of visual info arrives, 2 receptive fields
system that operates at high levels of light and involes the cones,
photoreceptor:
why transduction is backwards
bipolar cell that receives info from 50 rods
photopigments in rods that are extremely sensitive to light
bipolar cell that receives info from a single con
V1 2 receptive fields
wavelengths not felected by an object is it's...
specialized retinal cells that connect photoreceptors to bipolar cells
visual areas that respond to motion
cells in V1 that tune to lines of various angles
