Neuroscience Ch 6 Online Quiz
Stereoscopic depth perception requires the brain to detect:
retinal disparity
Most visual researchers suggest that area V1 neurons respond most strongly to:
spatial frequencies.
By comparing the slightly different inputs from the two eyes, you achieve:
stereoscopic depth perception.
The lateral geniculate nucleus is part of the
thalamus
Initially, researchers determined how many types of receptors we have for determining color:
through psychophysical observations
The fact that all colors on older televisions were created by combining only three different colors of light supports the ____ theory of color vision.
trichromatic
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
If light shines in the receptive field of a bipolar cell of the visual system, what effect will it have on the activity of that cell?
It may excite or inhibit the cell.
Why does the fovea provide the clearest, most detailed visual information?
Receptors are tightly packed there
What can cause a permanent blurring of vision for either horizontal or vertical lines?
asymmetric curvature of the eyes
The principle that allows you to perceive an orange shirt to be the same color under varying lighting conditions is known as
color constancy
Most neurons in the inferior temporal cortex that respond to a particular shape will be LEAST likely to respond to a:
figure-ground reversal
The retinas of predatory birds such as hawks:
have a greater density of receptors than do humans on the top half of the retina.
Cortical plasticity:
is greatest in early life, but never ends.
The most common form of color vision deficiency is due to
long- and medium-wavelength cones making the same photopigment.
Once within the cerebral cortex, the magnocellular pathway continues as a pathway sensitive to:
movement
Axons from the lateral geniculate extend to which area of the cerebral cortex?
occipital lobe
Damage to the dorsal stream may interfere with
reaching out to grasp an object
In what order does visual information pass through the retina?
receptor cells, bipolar cells, ganglion cells
Color constancy is the ability to
recognize the color of an object despite changes in lighting.
