1.When a person with severed corpus callosum sees an image in the left visual field, he isunable to distinguish what he saw, but when he closes his eyes, he is able to draw theimage of what he had seen. With that being said, he cannot name it but his left hand isable to illustrate it, this is because when a picture or word falls on the left fixation, theinformation transfers to the disconnected right half brain.2.Functional magnetic resonance imaging or fMRI measures brain activity by detectingchanges associated with blood flow. This technique relies on the fact that cerebral bloodflow and neuronal activation are coupled. When an area of the brain is in use, blood flowto that region also increases. Diffusion-weighted magnetic resonance imaging is the useof specific MRI sequences as well as software that generates images from the resultingdata that uses the diffusion of water molecules to generate contrast in MR images.
