Final answer:
Inter-neurons like horizontal and amacrine cells play a significant role in modifying the reaction at the blind spot through lateral inhibition, enhancing contrast in visual perception.
Step-by-step explanation:
The inter-neurons that modify reactions at the blind spot, also known as the optic disc, are implicated in contrast effects through a process called lateral inhibition. This occurs when horizontal cells carry signals from one rod or cone to others, as well as to several bipolar cells. When a rod or cone cell is stimulated, it triggers a horizontal cell to inhibit more distant photoreceptors and bipolar cells, enhancing the contrast by making regions in light appear brighter and dark surroundings appear darker. Furthermore, amacrine cells distribute information from one bipolar cell to many ganglion cells, contributing to the processing of visual information before it is transmitted to the brain through the optic nerve.
The optic nerve is composed of axons from the retinal ganglion cells, which carry visual information from the retina to different parts of the brain for higher processing. Different axons within the optic nerve carry information about various visual qualities, such as form, movement, depth, brightness, color, and fine detail. This complex web of interactions and pathways in the visual system allows for the integration of visual signals and the coordination of eye movements.
The optic nerve carries diverse visual information from the retina to the brain for further processing.
