A)Bipolar cells
B)Horizontal cells
C)Ganglion cells
D)Amacrine cells

Question

Horizontal cells are thought to be responsible for lateral inhibition in the retina. They make synaptic contact with photoreceptor cells and with bipolar cells. They receive signals from multiple photoreceptors and, in turn, suppress the activity of neighboring photoreceptors via inhibitory synapses. This enhances the contrast between light and dark stimuli and contributes to visual acuity.
