Center-surround receptive fields of bipolar cells are explained by: A. horizonta

Question

Center-surround receptive fields of bipolar cells are explained by:

A. horizontal cells from the surround receptive field release GABA onto a photoreceptor in the center of the receptive field

B. photoreceptors in the surround receptive field release GABA onto bipolar cells while photoreceptors in the center of receptive field release glutamate onto bipolar cells

C. photoreceptors in the center are always cones while photoreceptors in the surround are always rods

D. none of the above, bipolar cells do not have center-surround receptive fields

Explanation / Answer

Answer is D- none of the above, bipolar cells do not have center surround receptive fields. These cells connects the photoreceptor to ganglion cells. Ganglion cells are the ones who have center receptive field and center receptive field.
