Exam 3: Functional Architecture of the Visual Cortex

Unlike other cells, neurons in V1 with receptive fields that straddle the midline rely on axons that travel in the

The bundles of axons leaving the LGN are called

What is the significance of blobs (cytochrome oxidase-positive regions) in the primary visual cortex?

The elongated receptive field of some cells in V1 can be accounted for by

An axon originating outside of the primary visual cortex and terminating in layer IV is most likely coming from the

If an anterograde dye is injected into a single layer of the lateral geniculate nucleus, what will the resulting pattern of axons look like in the primary visual cortex? Why?

The primary visual cortex in a single hemisphere receives information from

Thick stripes in V2 receive information primarily from

You are conducting an experiment in which you inject radioactive amino acids into one eye. Several days later, you examine the visual cortex. What results do you see? Provide an interpretation for your observations.

Injection of horseradish peroxidase in thin stripes results in label in cells in

Adjacent hypercolumns will provide information about

Describe the retinotopic organization of the cortex.

Cells in V1 that have receptive fields that straddle middle of the visual field are found

Which of these cells, found in the retina, sends axons to the lateral geniculate nucleus?

What characterizes cells in blobs? What does this suggest about their function?

How many layers of cells are there in the primary visual cortex?

Which of the following is true of ocular dominance among cells in V1?

The transition between cortical areas V1 and V2 is marked by

Cells that respond to depth are often found in

In an experiment, you inject a neuronal tracer into a cell with a horizontal orientation preference. What is true of the cells in the cortical areas this neuron will project to?
