Final answer:
The signal from an image projected to the right visual field is sent to the left hemisphere, where the left visual cortex processes it. This crossing over occurs at the optic chiasm and is consistent with the overall organization of the cerebral cortex that generally receives and sends signals to the opposite side of the body. The correct option is b.
Step-by-step explanation:
When an image is projected to the right visual field, the signal will be sent to the left hemisphere. This is due to the way the visual pathway is structured. The visual field is projected onto the two retinae with sorting at the optic chiasm, where fibers from the nasal side of the retina cross to the opposite hemisphere.
Therefore, the right visual field is processed by the left visual cortex. Similarly, the left visual field is processed by the right visual cortex.
The concept of lateralization extends to other functions, such as language, which is localized in the left hemisphere in the majority of people.
The cerebral cortex controls motor functions and sensory perceptions on the opposite sides of the body. In the case of the visual system, this means visual stimuli from one side of our environment are processed in the opposing side of our brain.
Lastly, visual stimuli in the upper-left visual field will be processed in the lower-right region of the primary visual cortex due to the inverted and reversed topography of the visual pathway. Option b. is the correct one.
