The brain is a complex organ made of several parts, each with a specific function. The cerebellum is the part of the brain that is involved in motor control such as maintaining physical balance, thereby allowing a person to be in control of his/her body movements. It also coordinates voluntary muscle movements like walking by controlling the timing at which different muscles work together to produce accurate movement in a particular body part. Because of its involvement in motor control, damage to the cerebellum will result in difficulty in moving body parts and keeping maintaining physical balance. Muscles will not work properly together and a person 's movement will be exaggerated. The hypothalamus is another part of the brain that is situated below the thalamus. This small structure, which is often referred to as the thermostat of the body helps regulate body temperature, amount of fluid in the …show more content…
This structure is the little bridge that serves as a means of communication between the left and right hemispheres. Split brain is the term used to describe the result when the corpus callosum connecting the two hemispheres is severed due to conditions such as epileptic seizures. Because the two hemispheres communicate with each other through this bridge, severing the bridge produces a disrupts connection between them and prevent them from communicating with each other, hence the term split brain. Once separated, each brain hemisphere operates solely. Thus having a split brain can pose certain challenges in a patient, which can be tested in a controlled laboratory study. For example, when an image is shown to the left hemisphere of a split brain patient, he or she will only be able to point at it with the right hand but will not be able to say what it is because the left hemisphere, which controls processes occurring on the right side of the body is only involved in
For example, when researchers were working with the mental mirror box, a box that tricks the brain of a patient with a nonexistent limb that the limb is actually there by reflecting the healthy limb, they found that the individual feels as if the limb is present and healthy. Researchers also found that if an individual scratches a particular spot on his or her face, that fulfills the itching sensation that was previously felt on the nonexistent arm. This is because when one area of the brain is not being used, such as the arm map when the arm is amputated, another part of the brain map takes over, such as the face. This is an extremely interesting finding which explains why blind or deaf individuals experience such profound functioning in their other
It sends information for sleep, hearing, taste, and even eye movement. Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another. People who have a severed corpus callosum can essentially function as 2 different people at the same time, with the left half of their body performing one task, and the right half another. Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.
The forebrain helps people make wise decisions, damage to this area could result in an increase in impulsivity, leading this person to make harmful decisions. Damage to the forebrain may also result in memory loss. Patients with damaged frontal lobes often complain of minimal to substantial memory loss. Because of this, frontal lobe injuries have been associated with memory
Brain dysfunction and behavior The brain is vital to a humans existence. It directs almost everything we do in our daily life. The brain controls our voluntary movements, regulates involuntary activities, stores our memories, allows us to feel emotion and gives each individual a unique personality. Dysfunction in the brain either caused by deformity in development or through a serious head injury can alter a person's behavior.
The video Severed Corpus Callosum by the Scientific American Frontiers describes the case of a split-brain patient Joe. The recording starts on the campus of Dartmouth College in New Hampshire where Dr. Mike Gazzaniga, one of the leading scientists of this place has been working with Joe, a man with two brains for over a decade. Doctors have to perform brain surgery to correct his epileptic problem and to stop the daily seizures that were affecting his life. The procedure severed the connection between the two halves of his brain cutting the corpus callosum to prevent the spread of the electric storms that causes seizures. Yet, it also stopped the communication between the left and right halves of his brain.
The Impact of Concussions During Football Concussions have become a major problem in athletics throughout the entire world. Head injuries can impact many athletes lives in a negative way. Hard contact to the head of a player can damage the brain and the way he goes about life. The way football is played, equipment should be better equipped to prevent significant injuries such as concussions. Head injuries drive a player out of the sport earlier than normal, so the NFL has looked into the issue and has gone about bettering technology and equipment to prevent concussions in the future.
It develops from the rapid acceleration or deceleration of the brain within the skull, and its effects are usually accompanied by a bevy of physical, cognitive, and emotional signs and symptoms that make
Many concerns have centered in on the possible links between repeated concussions and chronic traumatic encephalopathy or CPE. Chronic traumatic encephalopathy is a serious, degenerative brain disease that affects a person’s ability to think. Chronic traumatic encephalopathy involves the progressive brain damage, particularly in the frontal region of the brain, which controls many functions including people’s judgement, emotion, impulsive control, social behavior and their memory. A signature feature of the disease is abnormal deposits of a protein called tau that accumulates around small blood vessels in brain crevices. Researchers believe that multiple blows to the head may dislodge the tau protein from the cell structure and cause it to form in clumps inside nerve cells.
(Traumatic Brain Injury in Adults, 2016.) It would be exceptionally frustrating for one to realize they aren’t able to perform the functions they once were able to. This could lead to an individual not finishing their degree, have a lesser feeling of self-worth leading to personal issues perhaps difficulty with developing relationships possibly leading to depression, and feasibly substance
Patients with brain injuries may require rehabilitation after being stabilized and out of immediate danger. The level and scope of rehabilitation depend on the severity of the deficits that a person has. For example, some people may have deficits in their physical majority and will have to regain strength and balance. In other cases, the rehabilitation may be needed to address cognitive deficits. Often a team of medical professionals specializing in different disciplines to provide a comprehensive treatment plan for the patient is needed.
Parts of the brain and their functions: the frontal brain with controls the higher mental processes. The midbrain, which controls emotions, motivations and the limbic system. The hindbrain which controls movement, and lower mental functions. 3. Split brain: when the corpus callosum is split it destroys the connection between the left and right side of the brain.
Moving to the left will reveal a nearly polar region, consisting of all your "practical, logical and scientific" brain functions. At the moment you're imagining two sides, completely different at that. But what were to happen if the line separating these two sides were to disappear? If both the "practical, logical and scientific" brain functions were to merge with the
Children that are age 0-4 and 15-19 are at an increased risk of getting a TBI, according to the centers for Disease Control and Prevention. A traumatic brain injury is a physical force to the head; for example being hit in the head with a bat or being shot in the head. A TBI can be classified as mild, moderate, or severe based on the size and nature of the injury. Symptoms may be seen right after the injury, but some may develop over time (Traumatic Brain Injury). There are many different types of Traumatic Brain Injuries and symptoms, causes, but simple things can prevent it.
In this video Dr. Vilayanur Ramachandran explains how the brain works and he began investigation about the “phantom limb syndrome”. Describe each disorder in detail, including symptoms/ disabilities and identify the brain areas/pathways associated with each disorder. Derek Steen had a motorcycle accident thirteen years ago, and he lost his left arm. Dr. Ramachandran was testing him Derek on his arm that no longer exist.
However, it’s never “completely” lateralized and one hemisphere cannot work completely on its own. It is important to know that the integration of the two hemispheres is essential. So I feel like using the word “depend” is too strong but we can say that one hemisphere is better with a certain task or function than the other. It is also important to remember that since healthy brains have corpus callosum, two hemispheres get to exchange information and work together. Furthermore, with the plasticity our brain has, we are
