Which of the following best describes the flow of visual information that occurs within the retina?
A) Photoreceptors respond and send excitatory or inhibitory information to retinal ganglion cells via bipolar cells.
B) Light signals are first processed in retinal ganglion cells, which form synapses with photoreceptors.
C) Signals pass directly from photoreceptor cells to ganglion cells.
D) Action potentials from bipolar cells pass information to photoreceptor cells before reaching ganglion cells.
E) Horizontal and amacrine cells modify the flow of information via axons in the optic nerve.

The flow of visual information in the retina occurs in the following way: Photoreceptors (rods and cones) respond to light and send excitatory or inhibitory signals to bipolar cells, which then transmit this information to retinal ganglion cells. Horizontal and amacrine cells also play a role in modifying the flow of information. Finally, the ganglion cells send action potentials down their axons, which form the optic nerve and carry visual information to the brain. Therefore, option A is the best choice as it describes the correct flow of visual information within the retina.
