there is the greatest spherical aberration here.

retinal ganglion cells here receive input only from cones.

retinal ganglion cells here have the smallest receptive fields.

retinal ganglion cells here have wavelength-selective receptive fields.

 retinal ganglion cells here have the largest receptive fields.

cones respond more quickly and recover more quickly than do rods.

cones have less photopigment and a less efficient light-activated cascade.

rods have only one wavelength sensitivity curve.

cones are less sensitive to absolute light levels than rods.

cones are concentrated at the fovea and responsible for axial vision.

None of the statements here is correct.

directly to retinal ganglion cells via electrical signalling.

directly to bipolar cells via electrical signalling.

light in the RF centre getting more focused

light in the RF centre getting brighter.

light in the RF surround getting brighter.

light in the RF centre and surround getting brighter.

either red or green wavelength light in the RF centre.

The enzyme Guanylate cyclase is able to produce more cGMP

The G protein, Transducin, is able to recover from light-induced inhibition

The ion channels allow in more Ca⁺⁺ into the cell

Rhodopsin recovers sensitivity from light-induced bleaching

The ion channels increase the standing current flow to repolarize the cell

consists of ON centre cells where the centre is selective for Blue light and OFF centre cells where the centre is selective for Yellow light.

consists of cells receiving most of their input from cones at the optic disk.

consists only of ON centre cells where the centre is selective for Blue or Yellow light.
