Chapter 5

The optic nerve is composed of axons from which kind of cell?

Ganglion cells

Professor Woodby is lecturing about the fovea. Which is she most likely to say?

It has the greatest perception of detail.

JC is looking at something located to his right (meaning it is within his right visual field). Where would that light hit his retina?

On the left half.

In what order does visual information pass through the retina?

Receptor cells, bipolar cells, ganglion cells

If you want to see something in fine detail, you should focus the light on which part of your retina?

The fovea

Professor Walker is lecturing about the law of specific nerve energies. She would not tell the class that _____.

although found in different places, the same kind of receptors on neurons are able to detect light and sound.

Various types of ____ cells refine the input to ganglion cells, enabling them to respond specifically to shapes, movement, or other visual features.

amacrine cells

Light has entered Joelle's eyes. After being detected by the photoreceptors, the information will be passed on to _____ cells.

bipolar cells

According to the trichromatic theory, we can perceive only three colors.

false

An object's location, color, and movement are all processed in the same part of the visual cortex.

false

Ivan has an impaired ability to recognize faces. His doctor diagnosed him with damage to the MT.

false

Parvocellular cells respond strongly to moving stimuli and large overall patterns

false

The coding of visual information in your brain results in an exact duplicate of the object's shape on the surface of the cortex.

false

The opponent-process theory explains why Dania's dress still looks blue even after she dims the lights.

false

The ventral stream of visual processing is important for identifying movement.

false

Youlanda has to wear glasses because her cornea doesn't adjust properly to focus the light onto the retina.

false

The retinas of predatory birds such as hawks ____.

have a greater density of receptors than do humans on the top half of the retina

in the back of each of Teresita's eyes, the axons of her ganglion cells all leave in one large bundle called the ______. As a result, this causes her to experience a _____.

optic nerve; blind spot

Professor Utz is giving a talk about how the eye processes light. He tells the class that once the bipolar cells receive input from ______, they send the message on to ______.

photoreceptors; ganglion cells

Light enters the eye through an opening in the center of the iris called the ____.

pupil

A complex cell responds to a pattern of light in a particular orientation.

true

Amacrine cells refine the input to ganglion cells, enabling them to respond specifically to shapes, movement, or other visual features.

true

Cecelia doesn't fall going down stairs because she can clearly see the edge of each step as a result of lateral inhibition.

true

Johannes Müller held that whatever excites a particular nerve establishes a special kind of energy unique to that nerve.

true

Photopigments are stable in the dark.

true

Simple cells are found exclusively in the primary visual cortex.

true

To see something with her best vision, Lore turned to look directly at it. This was so she could use her foveal vision.

true

According to the law of specific nerve energies, the brain tells the difference between one sensory modality and another by ____.

which neurons are active
