Lateral Inhibition
Group of answer choices
Interferes with processing of color information
Ordinarily heightens contrast at borders
Primary role is to help us detect motion
increases sensitivity to dim light
Ordinarily decreases contrast at borders
As you watch an object expand, rotate, or contract, this information is being processed primarily by which visual area?
Group of answer choices
Area MST (medial superior temporal)
The striated cortex
Area IT
Area V4
Fusiform gyrus
When rods are in the dark, sodium channels are kept
Group of answer choices
Closed, preventing sodium from leaving the cell
Closed, preventing sodium from entering the cell
Open, allowing sodium to leave the cell
Open; allowing sodium to enter the cell
In comparing rods to cones, which of the following is not true?
Group of answer choices
rods are not as sensitive to color as cones
there are more rods than cones
rods are used for photopic vision while cones are primarily used for scotopic vision
there are more rods in the periphery of the retina than cones
The aqueous and vitreous humors differ in that
Group of answer choices
the vitreous humor is replenished and the aqueous humor is not
the aqueous humor is replenished and the vitreous humor is not
the vitreous humor nourishes the cornea, whereas the aqueous humor nourishes the lens
the aqueous humor nourishes the cornea, whereas the vitreous humor nourishes the lens
Yan has had a stroke that affected an area of his brain that serves his macula, including the fovea of both eyes. What would you expect his vision to be like?
Group of answer choices
He will be able to see only what is exactly in front of him
He will be able to see only what is in his peripheral area
He will be totally blind
He will be able to see color, but not movement
The Trichromatic theory of color vision is based on _____________________, and best explains the processing of color at the level of the __________________
Group of answer choices
the existence of three types of cones; retina
the existence of three types of cones; primary visual cortex
antagonistic center surround receptive fields; retina
antagonistic center surround receptive fields; primary visual cortex
David is able to copy complex drawings perfectly, however he cannot name the object he has just drawn. Additionally, if he is shown an object, he has difficulty naming it, however, once he is allowed to hold the object in his hand and explore it in a tactile manner, he has a pretty good chance of naming it. Based on this description, what disorder best depicts David’s condition?
Group of answer choices
apperceptive agnosia
blindsight
associative agnosia
dichromatic colorblindness
Which of the following statement is FALSE when considering the parvocellular ganglion cells of the optic nerve?
Group of answer choices
they respond to high contrast changes, such as a black letter on a white background
they are responsive to color, especially red and green
they have very large receptive fields
they represent a majority of the ganglion cells
In the story “The Man who Mistook his Wife for a Hat”, what was the patient’s profession?
Group of answer choices
He was an attorney
He was a cab driver
He was a music teacher
He was an architect
He was a neurologist
In the chapter “Believing is Seeing” the patient called GY
Group of answer choices
Cannot “see” but can detect direction of motion and placement of objects
Cannot see shades of red and green due to color blindness
Cannot recognize familiar faces
Cannot see sharp contrasts of objects
In the reading “Believing is Seeing” the author attempts a mirror experiment with a patient suffering from neglect. What is the result of this experiment?
Group of answer choices
The patient recognized the pen held by the assistant but reached for the object in the mirror when asked to grab it
The patient became agitated, confused and refused to participate in the experiment, claiming that the author was trying to trick her
The mirror greatly helps the patient and she is able to appropriately reach for the pen held by the assistant
The mirror doesn’t help at all and she still denies seeing the pen held by the assistant
Doris was in a car accident that resulted in damage to the ventral cortical pathways of processing visual information. Which of the following deficits will she most likely report?
Group of answer choices
the inability to detect simple elements of motions, such as whether or not an object moved up or down in her visual field
problems with detecting objects in her right visual field but not the left visual field
the inability to detect motion, specifically motion that is more complex such as the direction of rotation of object
problems with detecting the color of objects
difficulties with correctly labeling objects visually presented, such as distinguishing between a picture of a cow versus a horse
