Dissecting Research #1 In this study‚ the researchers accomplished a series of tests that would focus on the injury of a corpus callosum. The corpus callosum is the nerve fibers that hold the right and left hemisphere of the brain together. The first test performed tested the visual abilities. The test “involved a board with a row of horizontal lights”. The patients were then told to stare directly at the center of the lights while the lights randomly would flash “across both the right and left

The corpus callosum(CC) links the cerebral cortex of the left and right cerebral hemispheresand is the largest fibre pathway in thebrain. It is approximately 10cms in length and is shaped‚ like most of the supratentorial structures‚ in a gentle upwardly convex arch. The postrior portion of the corpus callosum is called thesplenium; theanteriois called thegenu(or "knee"); between the two is the "body"‚ of the corpus callosum. genu : forceps minor : connect medial and lateral surfaces of the

by a bundle of nerve fibers called the corpus callosum. There are approximately 200 million nerve fibers that pass information back and forth between the left and right hemispheres of the brain. The fibrous tract aids in learning and memory. A birth defect can occur leading to the partial or complete absence of the corpus callosum. Agenesis means not formed or “absence of an organ”.

There is no difference between a split-brain hippocampus and a normal brain hippocampus. The cut done on the corpus callosum will not affect the hippocampus because the cut would not be deep enough. 1C. The cerebral cortex of the normal brain is different from a split-brain cerebral cortex because it has not been severed. In a split-brain cerebral cortex the two

I’m not sure if you ever heard of this‚ but there is research and evidence that suggests if someone is having uncontrollable seizures‚ splitting the corpus callosum in their brain significantly reduces seizures in people.

Our body is a large mass of cells which must be constantly supplied with fuel to run. We get this fuel from the food we consume‚ however‚ we do not continuously eat and there are periods of time when the digestive tract is empty. Therefore this essay will look at the biological control of eating. Although the body has short them and long term reservoirs of food‚ our body uses hunger signals to tell the brain when it is time to eat. There are many different reasons why this occurs and this will be

Split-Brain Patients: The independent functioning of the left and right hemisphere when no longer connected by the corpus callosum. The human brain is a dynamic and elastic processing unit that manages the great extent of human life. This entails both conscious and unconscious functioning of each human system. For example‚ the brain controls emotions through behaviors‚ physiological responses (both autonomic and hormonal)‚ and feelings in response to stimuli from the environment (Carlson

(severing of the corpus callosum) for the understanding of the connections between the left and right hemisphere. The first known split-brain surgical procedure performed on humans’ was in the early 1940’s by Van Wagenen and Herren‚ in which both intended to control seizures of patients who suffered intractable epilepsy (Francois Boller‚ Jordan Graffman‚ 2000). The procedure performed by Van Wagenen and Herren was based on the speculation as to the role of the corpus callosum in the spread of

It has been shown that anterior corpus callosum areas are larger in professional musicians [who began their musical training before the age of seven years old] than in non-musicians; however‚ studies have not been done to determine whether the difference was pre-existing or

It was interesting to read about the different brain hemispheres and how they work together‚ or in the case of “split brains” against each other. “Split Brain” is an operation that can be done‚ in which the corpus callosum is cut to control severe epilepsy. After the operation‚ the person basically has two brains that function individually on their own. The brain is such a powerful tool that it is amazing to see how much complexity there is to it.
