Why do you suppose that you are not normally aware of the blind spot in each eye?
Despite the presence of the blind spot, you do not consciously experience a “hole” in your vision. Why not?
Why is more of the visual cortex devoted to your central vision then to your peripheral vision? Don’t overthink this!

- Three patients have suffered destruction of different portions of their visual pathway. Patient 1 has lost the right optic tract, patient 2 has lost the nerve fibers that cross at the optic chiasm, and patient 3 has lost the left occipital lobe. Draw a picture of what each person would perceive through each eye when looking at a white wall.arrow_forward1) Those with blindsight think they can't see but can react to visual stimuli anyway. Why? they are faking being blind: they can see just fine, just like us the part of the cortex that controls conscious vision is still intact because the part of their visual system that controls visual reflexes is still intact because their eyes work fine and they also don't actually have any brain damage 2) Those with blindsight think they can't see but can react to visual stimuli anyway.

- Why does the blind spot from the optic disc in either eye not result in a blind spot in the visual field?arrow_forwardThere are a number of reasons for vision loss, both natural and unnatural. Use a blindfold to remove your sense of vision. how well your other senses adapt to the lack of visual input. How familiar is it? How does your perception of distance change?arrow_forwardWhy is it advantageous to become motion blind during voluntary eye movements? That is, why might we have evolved this mechanism?arrow_forward
- Why does your near point of vision move farther away as you age?arrow_forwardMr. Ally went to the eye doctor and complained about dark areas in his vision. He had never noticed it before. There is no pain. What is the diagnosis? Explain the reason behind floaters and dark areas in the visual field. How should the doctor treat Mr. Ally?arrow_forwardWhich senses correspond to which lobes of the brain? I know sound is located in the temporal lobe, taste is located in the parietal lobe, but I am not sure of the rest.arrow_forward
