The brain is such a complex and interesting thing to learn about. I learned a lot through the three- dimensional brain activity. Starting with the frontal lobe. The frontal lobes are located under the forehead. These lobes play a key role in movement and reasoning. They are also connected with the limbic system. The parietal lobe is at the top of the head. The parietal lobe gets its intel from the skin, it is very important to processing touch and helping determine how hot or cold it is and the pain in our body. The parietal lobe works with primary motor skills which are in charge of our voluntary actions. The temporal lobes are on the sides of the head. The temporal lobes are very important to speech and hearing. Within the temporal is the auditory center, this is what processes the nerve impulses sent from the ears. …show more content…
The occipital lobe is very important to us, as it takes information from the eyes and processes it. A common name for it is the “visual cortex”. If the occipital lobe is damaged it can cause blindness. Under this is the cerebellum, in charge of very important daily functions like balance and coordination as well as posture. The brain stem is the most basic part of the brain, as well as the oldest. For as basic as it is, it is key to survival. It controls things like breathing, sleeping and digestion as well as maintaining body temperature. The corpus callosum are fibers that are attached to the left and right sides of the brain. The function of the corpus callosum carries messages to and from each side of the brain. As mentioned earlier the limbic system helps to regulate heart rate and body temperature along with the brain stem. There are two parts of the limbic system the amygdala and the hippocampus. The amygdala which combines hearing and sight, it also helps link emotions with the
The brain has four major lobes. The frontal lobe, the parietal lobe, the occipital lobe, and temporal lobe are responsible for all of the activities of the body, from seeing, hearing, tasting, to touching, moving, and even memory. After many years of debating, scientist presents what they called the localization issue, Garret explains how Fritsch and Hitzig studied dog with conforming observations, but the cases of Phineas Gage’s accident in 1848 and Paul Broca’s autopsy of a man brain in 1861 really grabbed the attention of an enthusiastic scientific community (Garret 2015 p.6)
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.
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).
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality. The lobes of the brain are split between the right and left hemispheres of the brain. This well-designed arrangement is for the lobes to function correctly, so the two hemispheres of the brain can communicate with one
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. ...
It is the most important part of the body, because without a brain, none of us would be alive. In the brain, there are the cerebrum, the cerebellum, and the brain stem. The cerebrum holds memories, controls movement, and does problem solving and thinking. It is the biggest part of your brain. The cerebellum is underneath the cerebrum and controls coordination and balance.
In the conclusion, many people opinion would disagree say the heart was the most important part of the body. They didn’t know the only way the heart will working is by the brain, and the neurons are sending signals. Our body are like light switch your turn back on and off, plus you could even restart your body. In other cases, the brain is the most tangled part of the human body. It is the center of alertness and also rules all voluntary and involuntary movement and bodily functions. It can communicates with each part of the body throughout the nervous system, is a network of channels that carry electrochemical signals.
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality.

It contains the primary motor cortex and the prefrontal cortex, which extend from the central sulcus to the anterior of the brain. The posterior part of the frontal lobe is the precentral gyrus which is specialized in the control of fine movements. The very most anterior portion of the frontal lobe is the prefrontal cortex. The neurons in this area have up to sixteen times as many dendritic spines as neurons in the occipital lobe or primary visual cortex. As a result, the prefrontal cortex is able to integrate a great deal of information (Kalat, 2004).
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
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.
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
