Micah lost an eye in an accident as a child. Despite this, he is still able to see reasonably well in both visual hemifields. This is due to ___________.A. the fact that each eye receives information from both sides of visual spaceB.the fact that there are multiple visual areas in the brainC. the fact that the eyes and consequent V1 activity are not necessary for visual perceptionD. the fact that each hemisphere of the brain receives information from both sides of visual space
Question
Micah lost an eye in an accident as a child. Despite this, he is still able to see reasonably well in both visual hemifields. This is due to ___________.A. the fact that each eye receives information from both sides of visual spaceB.the fact that there are multiple visual areas in the brainC. the fact that the eyes and consequent V1 activity are not necessary for visual perceptionD. the fact that each hemisphere of the brain receives information from both sides of visual space
Solution 1
The correct answer is A. the fact that each eye receives information from both sides of visual space. This is because the visual field of each eye overlaps significantly with the other, allowing for a broad field of vision even with the loss of one eye. The left side of each eye's visual field is processed by the right hemisphere of the brain, and the right side of each eye's visual field is processed by the left hemisphere. Therefore, even if one eye is lost, the remaining eye can still provide information from both sides of visual space.
Solution 2
The correct answer is A. the fact that each eye receives information from both sides of visual space.
Here's why:
-
Each eye is divided into two visual fields: the left visual field and the right visual field.
-
Light from the left visual field of each eye is processed by the right hemisphere of the brain, and light from the right visual field of each eye is processed by the left hemisphere of the brain.
-
This is due to the optic nerves from each eye crossing at the optic chiasm. Some of the optic nerve fibers cross to the opposite side of the brain, while others stay on the same side.
-
Therefore, even if one eye is lost, as long as the optic nerves and visual areas in the brain are functioning, the person can still have a complete visual field.
-
In Micah's case, despite losing one eye, he can still see reasonably well in both visual hemifields because his remaining eye is still able to receive and process light from both sides of visual space.
Solution 3
The correct answer is A. the fact that each eye receives information from both sides of visual space.
Here's the step by step explanation:
-
The human visual system is designed in such a way that each eye receives information from both the left and right visual fields. This is due to the positioning and structure of the eyes, where the nasal (closer to the nose) half of each retina receives light from the visual field on the opposite side, and the temporal (closer to the temple) half of each retina receives light from the same side of the visual field.
-
When light enters the eye, it is refracted by the cornea and lens, causing it to cross over to the opposite side of the retina. This means that the left side of the visual field is processed by the right half of both retinas, and the right side of the visual field is processed by the left half of both retinas.
-
This information is then sent to the brain via the optic nerves. At the optic chiasm, the information from the nasal half of each retina crosses over to the opposite side of the brain. This ensures that all information from one side of the visual field is processed by the opposite hemisphere of the brain.
-
Therefore, even if Micah lost one eye, the remaining eye would still receive information from both the left and right visual fields, allowing him to see reasonably well in both visual hemifields.

Bill and Ben recently sustained damage to the occipital cortex and are experiencing blindness. Both are asked to identify whether lines presented on a computer monitor are either horizontal or vertical. Bill reports that he cannot see anything and he guesses the correct orientation of the line slightly less than 50% of the time (random chance). Ben reports reports that he cannot see anything but he guesses the correct orientation of the line with 70% accuracy. Which of the following statements is most accurate? Question 47 options: Bill and Ben both have cortical blindness and Ben is experiencing blindsight. Bill and Ben both have a blindsight and Ben is experiencing akinotopsia.
