Will, but only in ON-centre RFs, elicit the opposite effect to that elicited by the RF centre

Will, in 50% of RGCs, elicit the opposite effect to that elicited by the RF centre

Will, but only in wavelength-sensitive RFs, elicit the opposite effect to that elicited by the RF centre

Will, but only in OFF-centre RFs, elicit the opposite effect to that elicited by the RF centre

Always elicit the opposite effect to that elicited by the RF centre

Rods do not have a light adaptation system

Rods are non-functional in the day light

Rods have a less efficient light adaptation process because they dont use cGMP

Rods have a less efficient light adaptation process because they use Rhodopsin to produce cGMP

Phototrandsuction is so efficient in rods that light adaptation does not allow them to recover from background light

ON centre RFs are produced by the direct and indirect pathways for information flow but OFF centre RFs only by the indirect pathway.

only ON centre RFs have antagonistic surrounds.

light in the RF centre excites RGCs with OFF centre RFs but inhibits RGCs with ON centre RFs.

ON centre RFs are produced by cone inputs while OFF centre RFs are produced by rod inputs.

light in the RF centre excites RGCs with ON centre RFs but not RGCs with OFF centre RFs.

light in the RF centre getting brighter.

only red wavelength light in the RF centre.

 light in the RF centre and surround getting dimmer.

light in the RF centre getting dimmer.

 either red or green wavelength light in the RF centre

dark adaptation.

visual acuity.

wavelength sensitivity.

 light adaptation.

flicker sensitivity.

because of the flow of information through horizontal and amacrine cells.

because there are two types of receptors sending information to each RGC.

because bipolar cells can transmit information in both directions.

because adjacent RGCs contact each other.
