WebbWithin the layers of the retina, light impulses are changed into electrical signals. Then they are sent through the optic nerve, along the visual pathway, to the occipital cortex at the posterior (back) of the brain. Here, the electrical signals are interpreted or “seen” by the brain as a visual image. WebbIn the visual system, the right half of the brain receives information about the left half of the visual field (note: not just from the left eye). Note that the fibers cross over at the optic chiasm. Visual deficits due to lesions at different points in the pathway: Suppose someone comes in complaining of vision problems.

WebbVisual Pathway Flowchart. Visual perception is the capacity to comprehend one’s surroundings through one’s sense of sight. The sequential step that takes place during visual perception is termed the visual process. Here, let’s have a brief look at the components and steps that comprise the visual pathway. Webb1 juli 2012 · 22. Visual Cortex Much of the primate cortex is devoted to visual processing. • In the macaque monkey at least 50% of the neocortex appears to be directly involved in vision, with over twenty distinct areas. • Some of the areas concerned are quite well understood, others are still a complete mystery. 23.

WebbOnce inside the brain, visual information is sent via a number of structures to the occipital lobe at the back of the brain for processing. Visual information might be processed in parallel pathways which can generally be described as the “what pathway” and the “where/how” pathway. WebbThe “what pathway” (ventral stream) is involved in object recognition and identification, while the “where/how pathway” (dorsal stream) is involved with location in space and how one might interact with a particular visual stimulus (Milner & …
