B)that over 50% of the total cortex is involved in vision. C) that certain processing regions are enlarged in the brains of chess masters D) that there are signilicanr differences between human and mmonkey brains 32) Axons extending from the nasal part of the retina project to the side of the brain, 32) whereas axons from the remainder of the retina project to the part of the brain. A) Dorsal, ventral B) Medial, lateral C) Same side (ipsilateral), opposite (contralateral D) Opposite (contralateral), same side (ipsilateral) 33) 33) As we age the lens loses its ability to A) assume a "flattened" shape. C) block harmful radiation B) constrict. D) bend light strongly 4) Exploratory eye movements are necessary because 34) A) the region of the retina that supports detailed vision is quite small B) they are reflexive. C) they add motion signals to an otherwise staionary scene. D) not al locations in scenes are equally intersting or informative 35) 35) Damge to the parvocellular system A) causes little effect if the magnocellular system remains intact. B) Results in color visiondeficits C) impairs depth perception D) impairs motion perception 36) What is NOT true about cones? 36) A) In dark adaption, our cones recover from bleaching much faster than the rods and continue to be more sensitive to light than our rods while we remain in the darkened B) There are no blue cones in the fovea, but they are found in the periphery of the retna. C) Red cones are most sensitive to long wavelenghs of light green to middle wavelengths and blue to shorter wavelengths of light. D) People have different numbers of red and green cones, but all have fewes, but the same number of blue cones. 7) What is the correct sequence of light entering the eye and reaching the retinina? 37) A) cornea, iris, lens, retina C) cormea pupil, lens, retina B) cormea, lens, pupil, retina D) iris, pupil, cornea, retina 38) The optie chiasm A) is where the M and P ganlion cell pathways diverge. B) is the site of partial decussation of ganglion cell axons. C) is where the first pot-retinal synapses are found D) is Y-shaped 39) 39) Why don't we notice our retinal blood vessels? A) They lie behind the retina B) There are none. C) They move too quickly D) They cast only diffuse shadows and are motionlessExplanation / Answer
Answer:
31.
Study of brain region responsible for visual information processing revealed that there are significant differences between humans and monkies.
Hence,option (d) is correct answer.
32. Axons from the nasal side of the retina project to the opposite side of the brain, whereas axons from the remainder of the retina project to the same side of the brain.
33.
As we age lenses loses its ability to bend light strongly.
Hence,option(d) is correct answer.
34.
Exploratory eye movement is necessary because they add the motion signals to otherwise stationary scenes.
Hence,option (C) is correct answer.
