What happens to pigment molecules in photoreceptors when struck by light?

• They change color

• They change temperature

• They change shape

• They dissolve

Which cells in the retina transmits signals vertically from photoreceptors and horizontally to inner layers - ganglion cells and americnan cells?

• Horizontal cells

• Bipolar cells

• Ganglion cells

• Photoreceptors

What is the role of ganglion cells in vision?

• To transmit graded potential to horizontal and bipolar cells

• To pool information from many photoreceptors

• To transmit output signals to the brain through the optic nerve

• To transduce light energy into neural energy

Which pathway receives input from diffuse bipolar cells by M ganglion cells

• Magnocellular pathway

• Parvocellular pathway

• Lateral geniculate pathway

• All of the above

What is the primary function of M ganglion cells?

• Fine visual acuity

• Color processing

• Motion processing

• Shape processing

Which ganglion cells have poor temporal resolution and good spatial resolution?

• M ganglion cells

• P ganglion cells

• Both A and B

• Neither A nor B

Which ganglion cells have (good) temporal resolution and (poor) spatial resolution?

• M ganglion cells

• P ganglion cells

• Both A and B

• Neither A nor B

Which pathway receives input from P ganglion cells?
