When the more verbal left hemisphere sees the picture that the hand drew, the patient is able to name it (assuming the left hemisphere can interpret what was drawn by the left hand).Much of what we know about the functions of different areas of the brain comes from studying changes in the behavior and ability of individuals who have suffered damage to the brain. Web. On the other hand, the right side of the brain is responsible for creative activities like arts and connecting to others in an emotional way. Cerebellar ataxia and diplopia have been described in some patients. Messages travel to and from the brain through every segment.Some sensory messages are immediately acted on by the spinal cord, without any input from the brain.

Therefore, the lower on the spine damage is, the fewer functions an injured individual will lose.Bob Woodruff, a reporter for ABC, suffered a traumatic brain injury after a bomb exploded next to the vehicle he was in while covering a news story in Iraq. A 2013 study looked at 3-D pictures of over 1,000 people’s brains. For instance, a split-brain patient is unable to name a picture that is shown in the patient’s left visual field because the information is only available in the largely nonverbal right hemisphere. However, over time and with the aid of intensive amounts of cognitive and speech therapy, Woodruff has shown an incredible recovery of function (Fernandez, 2008, October 16).One of the factors that made this recovery possible was neuroplasticity.

Because of it, the brain can act. PrP amyloid angiopathy involves the walls of small and medium-sized parenchymal and leptomeningeal blood vessels, with PrP amyloid fibrils being adjacent to and within the vessel walls (.Frontal – motor control of the opposite side of the body, insight and control of emotions and, in the dominant hemisphere, output of speech.Temporal – memory and emotions and, in the dominant hemisphere, comprehension of speech.Parietal – sensation of the opposite side of the body and appreciation of space, especially in the non-dominant hemisphere.The surfaces of the cerebral hemispheres show many convolutions consisting of cortical gyri separated by.The brains of members of the same species have very similar patterns of fissures, although there is some variation. This vascular territory includes the medial aspect of The occipital pole is the posterior end of each,If the upper part of either hemisphere is removed, at a level about 1.25 cm above the,If the remaining portions of the hemispheres be slightly drawn apart a broad band of white substance, the corpus callosum, will be observed, connecting them at the bottom of the,Each labium is part of the cingulate gyrus already described; and the groove between it and the upper surface of the corpus callosum is termed the.If the hemispheres are sliced off to a level with the upper surface of the corpus callosum, the white substance of that structure will be seen connecting the two hemispheres.The large expanse of medullary matter now exposed, surrounded by the convoluted margin of gray substance, is called the centrum semiovale. The Cerebral Hemisphere is one half of the brain, either the right or the left. It is a bilateral, or two-sided, structure that can be separated into distinct lobes.

Neuroplasticity can involve creation of new synapses, pruning of synapses that are no longer used, changes in glial cells, and even the birth of new neurons. The signal passes from the sensory nerve to a simple processing center, which initiates a motor command. The brain can thus be described as being divided into left and right cerebral hemispheres. It is a heavily bilobed structure. It is an insidious disease and usually has a long and protracted clinical course of weeks to months.

A stroke, caused by an interruption of blood flow to a region in the brain, causes a loss of brain function in the affected region.
