Recommended: Does frontal lobe injury affect cognitive function
Being an important part of our body, the Frontal Lobe serves to regulate higher intellectual functions such as reasoning, thoughts, and the behaviors within human beings (Frontal Lobe MedicineNet). It is the home to the personality of a person and the ability to communicate with other humans. The frontal lobe is also responsible for all of the primary motor functions, or the ability to move muscles, and two key areas related to speech. The frontal lobe is larger and more developed in humans than any other organism (Frontal Lobe Anatomy). Causing damage to this organ will bring change to the life style of the affected; because of this the frontal lobe must always be protected because injury to it can have severe consequences.
In addition, causing damage to this lobe can cause impairments in judgment, give the affected a lower attention span and organizational ability, as well as a loss of motivation. When they are compromised, a person may become impulsive, act rashly, and adopt risky behaviors such as drinking and smoking. Damage to the frontal lobe most often occurs as a result of being in a vehicle crash, falling of motorcycles, and being shot at by firearms, such as a pistol or rifle. To prevent this it is best to always wear a seat belt, make sure children are in safety or booster seats at all time, and to always wear a helmet

After the incident, Gage's personality was said to have changed drastically. His friends claimed that the once kind and hard working Gage had changed after the accident to a lazy and rude man until he died years later. However, this incident did allow doctors and psychologists, doctors who study the mind, to analyze the brain and see the importance and functions of the frontal lobe (The Brain Made
Gage's accident effected him with many personality changes. His physician Dr. J.M. Harlow noticed that Gage's personality was radically altered after the accident. Gage was fitful, irreverent, indulging, manifesting but little deference for his fellows, impatient of advice when it conflicted with his desires. Before Gage's accident he possessed a well-balanced mind, was known as a smart businessman, energetic, and was persistent in executing all of his plans of operation. His friends and acquaintances said he was no longer "Gage" due to his completely changed mind. After his injury he lost his job with the...
In times past and recent, a person may have expressed their gratefulness to another person with a statement such as, no one expected to lose their life when they woke up today. This case of Phineas Gage is still a modern mystery to some people, in as much, the fact that he survived this horrific incident was a true blessing and a wonder for all to see. At a period in history where the brain’s activities and functions was in high debated, scientist wanting to prove their theory and every situation that involved the brain an avenue in which they used to fuel their research, Phineas gave them an enormous amount of evidence. In making the point that the brain has different lobes that has control over their respective areas and motor skills of
Prior to reading this book, I understood that brain structure and function are related; however, I did not realize how damage to the brain could have such widespread, yet restrained, effects. Sarah’s ability to use the entire left side of her body in movement and sensation was greatly compromised by a brain bleed and damage to the right side of her brain, meaning that different structures must have been affected by the damage; however, Sarah is still able to use the left side of her body if she recognizes it is there and concentrates on using it. With brain injury, I did not realize the extent to which injuries differ. Injuries can occur in different scenarios, such as a car accident, and impact all aspects of life, depending on the severity. The difference between whether an injury hinders or disables a person from performing a function lies in where the damage is done and how tremendous the impact is. Sarah’s injury did not disable her from a task such as seeing, but it did hinder her ability to see anything on or surrounding the left side of her body without concentration. In addition, I was unaware of the existence of hemispatial neglect syndrome. It is an interesting concept because although Sarah still had to ability to see and use the left side of her body with concentration, seeing
(Phineas Gage book) This ended up killing Gage. Phineas Gage’s contribution is that he taught doctors, scientist, and people more about the brain and
The Frontal Lobe: Is the anterior part of cerebral hemisphere of the cerebrum of the brain, extending back to region called the central sulcus is a deep cleft on the upper surface of the brain. The frontal lobe is for intelligence which carries out high mental procedures such as thinking, judgment making, and forecasting. The human body uses their frontal lobe nearly every day. The frontal lobe
Think about it, an average teen in this world has just been diagnosed with a type of incurable dementia which will forever change his or her life. Frontotemporal dementia (FTD) is one of the less common forms of dementia. It is when the nerve cells in the frontal lobe die and over time the brain tissue shrinks. Frontotemporal dementia is mostly found in people who are in their teens or twenties. It can affect young people in a very negative way. They start to get aggressive and as the disease gets worse they lose friends and have a difficult time in school and understanding things. Frontotemporal dementia is a rare disease that is on the rise and affects the people of the younger generation.
Traumatic brain injury (TBI) is a major cause of death and disability worldwide for which there is no cure. Many patients who survive from TBI may experience permanent cognitive loss, behavioral issues, and emotional disturbances, which require daily medical or social attentions.[1, 2] It is believed that over 2% US population is experiencing TBI-associated disabilities which create an annual burden evaluated at $60 billion on direct (medical service) and indirect (loss of productivity) costs.[3, 4] Traumatic brain injury is complex which consists of a mechanical trauma (primary injury) and a resulting biochemical cascade (secondary injury), and lead to a wide diversity of symptoms.[5]
Neuroscience and social work how do they relate? For many people, when they hear the term social worker, they automatically think of child welfare and food stamps, yet no one thinks of a social worker being a psychiatrist or a counselor even though these are considered social work as well. This is how neuroscience and social work might be related. Social work is a practice-based occupation that promotes social adjustment, growth, and social structure. The main beliefs of social work are social integrity, civil liberties, combined responsibility and respect for diversities. There are many types of social workers, such as family services worker, psychiatrist, and many types of counselors.
The frontal lobe comprises a third of the brain and it enables us to engage in higher cognitive functions such as planning and problem solving (Jonides & Smith, 1999). The frontal lobe is divided into 3 regions, the motor cortex, premotor cortex, and prefrontal cortex. The motor cortex is located in the precentral gyrus and directs fine motor coordination. The premotor cortex is involved in planning, organizing, and integrating body movements. The prefrontal is involved in executive functions, including short-term memory, working memory, decision making, and prioritizing behaviors (Wilson, 2003). Some of the frontal lobe disorders than can cause brain damage and behavioral changes are Huntington’s disease, infection, stroke, tourettes, dementia, epilepsy, Parkinson’s disease, tumors, closed head injury and traumatic brain injury (Chow, 2000).
Although the brain only weighs about three pounds, it is a very powerful and essential organ in the body (Brain Structures and Their Functions). The cerebrum, cerebellum, and the brain stem are the three main parts of the brain. The cerebrum fills up most of the skull, its main functions are for remembering, problem solving, thinking, and feeling (Bellamy 23). It also controls movement throughout the body. The cerebellum is located towards the back of the head. It controls mostly just coordination and balance (Brain Structures and Their Functions). The brain stem is underneath the cerebrum and in front of your cerebellum. It attaches the brain to the spinal cord and controls functions like breathing, digestion, heart rate and blood pressure (Carter 12). The brain is also divided into halves. The left side of the brain controls the right side of the body, while the right side of the brain, controls the left side of the body (Bellamy 17).
The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
The brain is the most important organ in the body with our heart. It controls every action, thoughts and regulates our bodily function. It is divided into section, each of them are responsible for various process. Before we can understand dopamine, we must talk about the different parts of the brain. The frontal lobe is the main difference between us and animals. ...
The human brain weighs approximately three pounds and contains approximately 100 billion neurons (Farmer, 2009, p. 21). The brainstem is the oldest part of the brain and it controls important functions such as heart rate, blood pressure, breathing, and our fundamental emotions such as happiness or sadness. It also sends and receives information from the spinal cord. Above the brainstem is the thalamus, which connects to the higher cortical regions of the brain. It manages sensations such as touch. The hippocampus surrounds the thalamus and it manages spatial working memory, learning, and emotion. The cerebellum is located at the back of the brain is responsible for movement and cognitive and emotional functions. The outer region of the brain is the cerebral cortex and is divided i...
The case of Phineas Gage is a rather remarkable one. During the late 1800s, "doctors" didn't fully understand brain trauma so Mr. Gage's injury was not fully understood. However, after decades of research we now understand what damage to the frontal lobe can do to an individual's personality. Research has concluded that damage to the frontal lobe can result in changes in emotional behavior, promiscuity, motivation, lethargy, and inhibition. Individuals with brain trauma can also be prone to violent outbursts. I can definitely understand how bran injuries can result in changed behavior since the brain is essentially the master control of the human body. In addition to Phineas Gage, another famous case that illustrated how a traumatic brain
Most of the body’s functions such as, thinking, emotions, memories and so forth are controlled by the brain. It serves as a central nervous system in the human body. The mind is the intellect/consciousness that originates in the human brain and manifests itself in emotions, thoughts, perceptions and so forth. This means that the brain is the key interpreter of the mind’s content. Jackson and Nagel seem to resist identifying what we call “mental events” with brain events, for different reasons, while J.J.C. Smart takes the opposing view.
