Collectively,the rods and cones are known as:

The photopigment in cones is called iodopsin.

The fact that specialized visual functions occur in specific locations illustrates ___.

If you have a problem with form vision,what are you not seeing?

To "see" gradual variations in shading,we rely on cells that respond best to ___ but to "see" abrupt changes in light versus dark,we rely on cells that respond best to ___.

The ___ is a neuron in the visual cortex that responds best to a line or an edge with a particular orientation at a specific place on the retina.

The fact that the different layers of retina perform some processing,and then information is passed on to where more processing is conducted in the lateral geniculate nucleus and then passed on to the visual cortex where still more is performed,illustrates ___.

Which of the following describes the anatomical arrangement of the visual system?

The rods and cones are the photoreceptors.

Cones in the retina:

Axons from the retina first synapse in the optic chiasm.

Cones in the retina:

The translation of light energy into neural energy occurs in the:

The inferior temporal cortex:

When a photopigment is exposed to light,it:
