Which of the following best describes the visual processing that occurs within the retina?
A) Impulses are processed within individual photoreceptors and then travel to the brain.
B) Light signals are processed in the first layer of retinal cells the light hits, and the signal from these is passed on to the bipolar cells.
C) Signals pass directly from photoreceptor cells to ganglion cells.
D) Action potentials in photoreceptor cells directly affect both bipolar cells and ganglion cells.
E) A complex pattern of synapses between photoreceptors, horizontal cells, amacrine cells, and bipolar cells determines the activation of ganglion cells.

Question

Quizplus · Accepted Answer

The retina processes visual information through a complex network of cells. Photoreceptors (rods and cones) capture light and convert it into electrical signals. These signals are then modified and integrated through interactions with horizontal cells, bipolar cells, and amacrine cells before being transmitted to the brain by the ganglion cells. This intricate pattern of synapses allows for the initial processing of visual information, including aspects like contrast and motion, directly within the retina before the information is sent to the brain.
