 another example of a projection fiber this is a distinction of a brain and we can see this radiating fan-shaped structure here this is a projection fiber which has been given a specific name called the corona radiata radiating like a crown so this is a projection fiber another example of a projection fiber is this as you can see this is a more diagrammatic representation the fibers are radiating like a crown that's why it is called the corona radiata we should see subsequently that this corner radiata has got many components which are all labeled here I would like you to take a look at this fact that this corona radiata has been indented from the lateral aspect by one nucleus here which is referred to as the lentiform nucleus and another important point is this corona radiata which is located just inside the brain inside the white gray matter of the brain as these fibers converge cordially they become more tightly packed and in the region of the basal ganglia they come to be known as the internal capsule which is going to be the main topic for today this is another picture a DTI diffusion tensor imaging with white matter tractography of the projection fibers more specifically one component of the prediction fibers inside the internal capsule which we shall describe which is referred to as the corticospinal tract so this is one side corticospinal tract descending through the pons into the medullary pyramids and this is the other corticospinal tract so this is a DTI diffusion tensor imaging with white matter tractography
