Lateral inhibition

Optical Illusions

Lateral inhibition refers to a type of image processing which occurs in
(A) the retina.
(B) the optic nerve.
(C) the brain.
(D) the cornea.

Lateral inhibition refers to a type of image processing which occurs in
(A) the retina.
Yes. --- Cells inhibit each other.

Lateral inhibition refers to a type of image processing which occurs in
(B) the optic nerve.
No. --- That just carries signals.

Lateral inhibition refers to a type of image processing which occurs in
(C) the brain.
No. --- This occurs before the signal gets there.

Lateral inhibition refers to a type of image processing which occurs in
(D) the cornea.
No. --- The cornea only helps focus light.

By the time signals from the visual cells in the retina get to the higher centers of the brain, they are in the form of
(A) summaries of specific features.
(B) averages over nearby cells.
(C) sets of binary digits.
(D) precise maps of the image.

By the time signals from the visual cells in the retina get to the higher centers of the brain, they are in the form of
(A) summaries of specific features.
Yes. --- Local features like angles between edges.

By the time signals from the visual cells in the retina get to the higher centers of the brain, they are in the form of
(B) averages over nearby cells.
No. --- That would just give a fuzzy picture.

By the time signals from the visual cells in the retina get to the higher centers of the brain, they are in the form of
(C) sets of binary digits.
No. --- OK for a computer but not for a brain.

By the time signals from the visual cells in the retina get to the higher centers of the brain, they are in the form of
(D) precise maps of the image.
No. --- that would be too much information to handle.

Optical illusions are primarily the result of the way images are
(A) formed on the retina.
(B) processed in the eye.
(C) reconstructed by the brain.
(D) transmitted to the brain.

Optical illusions are primarily the result of the way images are
(A) formed on the retina.
No. --- The images are usually correct.

Optical illusions are primarily the result of the way images are
(B) processed in the eye.
No. --- It is partly responsible but there is no illusion unitl later.

Optical illusions are primarily the result of the way images are
(C) reconstructed by the brain.
Yes. --- The brain often gets the big picture wrong.

Optical illusions are primarily the result of the way images are
(D) transmitted to the brain.
No. --- that is part of the reason but the illusion comes later.
