As we progress from bipolar cells to ganglion cells to later cells in the visual system, what happens to the size of receptive fields? a. They become larger. b. They become smaller. c. They stay the same size. d. They vary in size unpredictably.

The stimuli can generate electrical impulses in the sensory region. The area where it is generated is called the receptive field. An impulse is generated in the sensory neuron.
The receptive field is present for all the sensory regions. As the body surface and other parts of the body are sensory, therefore all the body has a receptive field.
The receptive field of the bipolar cells of the eye is in the shape of a circle. The effect of reception is different in the center and in the region around it.
The ganglionic cells have an elliptical-shaped receptive field smaller than bipolar cells. This allows having fine details of the vision.
The smaller the receptive field finer details are encoded.
Hence b is the correct option.
