Final answer:
The correct answer is B, which states that blindsight can occur due to separate neural pathways for detailed vision and movement. These pathways can process certain aspects of vision without the need for conscious perception, even if the primary visual cortex is damaged.
Step-by-step explanation:
The phenomenon of blindsight is an intriguing aspect of visual perception where individuals can respond to visual stimuli without consciously seeing them, often due to damage to the primary visual areas in the brain. When it comes to explaining blindsight, option B. there are separate neural pathways for perception of detailed vision and perception of movement is correct. This is because, in addition to the main visual pathway, which includes the visual cortex, there are other pathways that bypass this primary area and instead project to other parts of the brain that can still process certain aspects of vision, such as movement or spatial location, without the individual being aware of it.
For example, rods and cones in the retina have neural connections not just to the visual cortex, but to other areas of the brain, facilitating some processing of visual information even if the main pathway is damaged. Additionally, we need to consider other factors such as how our visual system might fill in blind spots or process color constancy, which are examples of the complex mechanisms involved in vision that function even without conscious perception.
