-
The law of specific nerve energies states that:
every stimulation of the optic nerve is perceived as light.
-
In what order does visual information pass through the retina?
receptor cells, bipolar cells, ganglion cells
-
The optic nerve is composed of axons from which kind of cell?
ganglion cells
-
Which of the following characterizes the fovea?
It has the greatest perception of detail.
-
Which receptors are responsible for the perception of color?
cones
-
Which theory emphasizes the idea that color vision depends on the relative responses of three kinds of cones?
Young-Helmholtz theory
-
Color constancy is the ability to:
recognize the color of an object despite changes in lighting.
-
The enhancement of contrast at the edge of an object is the result of:
lateral inhibition in the retina.
-
In the vertebrate retina, which cells are responsible for lateral inhibition?
horizontal cells
-
Which ganglion cells, if any, are located mostly in or near the fovea?
parvocellular
-
Visual information from the lateral geniculate area goes to the:
primary visual cortex.
-
Once within the cerebral cortex, the magnocellular pathway continues as a pathway sensitive to:
movement.
-
Damage to the dorsal stream may interfere with:
reaching out to grasp an object.
-
Which of the following would most strongly excite a simple cell in the primary visual cortex?
square picture frame
-
What is one way to determine whether a given cell in the primary visual cortex is "simple" or "complex"?
Whether it can respond equally to lines in more than one location.
-
An inability to recognize objects despite otherwise satisfactory vision is called:
visual agnosia.
-
Color perception depends MOSTLY on the:
parvocellular pathway.
-
The ability that you have to determine that your eyes are moving, instead of the room that you are in, is a function of which brain area?
area MST
-
Most of the neurons in the visual cortex of very young kittens respond to:
both eyes, and continue that way.
-
Children with strabismus fail to develop:
stereoscopic depth perception.
