Exam 6: The Visual System

The parvocellular layers of the lateral geniculate nuclei get their name from the fact that the neurons in these layers are

Scotomas are located by

In humans, the axons of retinal ganglion cells whose cell bodies are in the left temporal hemiretina

The brightness of a light depends on its

Light passes through layers of the retina in which of the following sequences?

Most lateral geniculate neurons terminate in

Neurons with receptive fields in the fovea

Describe the dorsal and ventral streams. Describe two theories of their functional difference and the evidence on which each theory is based.

According to one theory, the __________ stream controls behavior in the absence of conscious awareness.

The absorption spectrum of rhodopsin closely corresponds to the

There are more rods

The perception of an edge is in effect the perception of a

With respect to vision, wavelength is to intensity as

Nonexistent stripes of lightness and darkness that accentuate the perception of edges are often called

Current evidence suggests that some cases of blindsight may be mediated by

The color and brightness of large unpatterned surfaces are not directly perceived; they are filled in or completed by a process called

The bleaching of rhodopsin by light

Prosopagnosics

In contrast to the "where" vs. "what" theory, Goodale and Milner have argued that the respective functions of the dorsal and ventral streams are

Prior to migraine attacks, sufferers often experience
