ON-center ganglion cells synapse with which type of bipolar cells?

ON-center ganglion cells are specifically wired to synapse with ON-center bipolar cells. This relationship is a key feature of the visual processing system in the retina. ON-center bipolar cells respond to increases in light intensity in their receptive field. When light stimulates the photoreceptors (such as rods and cones) in the center of the ganglion cell's receptive field, it causes depolarization of the ON-center bipolar cells. This depolarization then leads to an increase in the firing rate of the ON-center ganglion cells.

The functional role of ON-center bipolar cells is to transmit signals that correspond to increments of light, allowing the visual system to detect edges and contrasts in the visual environment effectively. This synaptic arrangement aligns with how the visual system processes light and dark differences, ultimately contributing to visual perception.

In summary, the correct answer highlights the critical connection between ON-center ganglion cells and ON-center bipolar cells, which is essential for the processing of light stimuli in the retina.
