Depends on the Na+/K+ pump in the inner segment of photoreceptors

Depends on blocking the influx of Ca++ into photoreceptors

Depends on the standing current flow in photoreceptors

Depends on allowing the influx of K++ into photoreceptors

Depends on activating more PDE

highest in the region where axons of retinal ganglion cells form the optic nerve leaving the eye.

 lowest in the retinal regions where receptive fields of retinal ganglion cells are smallest.

highest in retinal regions where only rods are present.

highest, in both daylight and at night, in the region where cones are maximally concentrated.

 highest in retinal regions where functioning retinal ganglion cells have the smallest receptive fields.

The RF is the change in resting membrane potential of the RGC produced by light.

The RF is the cell which is responsible for the direct pathway from rods to RGCs.

The RF is made up of centre and surround regions which produce opposite effects on activity in the RGC.

The RF is made up of horizontal and amacrine regions which produce opposite effects on RGC activity.

The RF represents the area of the retina which excites the RGC.

Found in rods and cones

Found only in rods

Found only in the fovea

Found in the fovea and para-fovea but not retinal periphery

Found in inner and outer segments of the retina
