Neurology: All in your Head Essay

Secondly, the brain is an immensely complicated organ to understand and study. It is composed of major parts, lobals, systems, glands, cells, tissues. Each piece

“The Human Brain”, by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body’s activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists

The brain can be considered the most complex organ in the body and the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists have identified areas within it that perform specific functions. This makes the brain interconnected by three different layers: the central core, the limbic system, and the cerebral cortex. All of which contain structures that regulate everyday life and psychological function.

Let’s begin by discussing the parts and function of our brains. The neo cortex is the largest part of the brain and the most important. This part of the brain is divided into four different sections: the temporal lobe, occipital lobe, parietal and the frontal lobe. These four sections are located on either the right or left hemisphere of the brain they are connected by axons that send messages to and fro between both hemispheres and to specific parts of the brain then to the body. Our neo cortex is what makes us so different from our primate cousins.

Your brain is a very powerful thing. It controls everything about you. Your thoughts, your actions, your emotions. Everything we see, feel and do are actions of our brain. Our brains are the most complex things in this world. They start to develop at just 4 weeks in the womb. They form more connections then stars in the sky. In the Pbs series “The Secret life of the Brain” they divide your brains life into 5 parts, the babies brain, the child’s brain, the teenage brain, the adult brain and the aging brain.

The six primary structures of the brain are the Brain Stem, the Cerebellum, the Occipital Lobe, the Temporal Lobe, the Parietal Lobe, and the Frontal Lobe. The Brain Stem is underneath the limbic system. It is responsible for the basic functions such as breathing, heartbeat, and blood pressure. The Cerebellum is behind the spinal cord. Its function is coordination for movement, posture, and balance. The Occipital Lobe is at the backside of the brain. Its function is processing visual information, such as color, shape and motion. The Temporal Lobe is over the ears and its function involves hearing, language processing and memory. The Parietal Lobe is at the

“It plays such a vital role in human life that many consider it the essence of life.”(Huffman 70) It contains the frontal lobes, parietal lobes, the occipital lobes and temporal lobes. The Frontal lobes receive signals from the other lobes such as motor control, speech production and other higher functions. The parietal lobes Receive signals for bodily sensations and interpret them. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing, language, memory and some emotion. All of these parts of the brain conduct essential bodily functions and need to be functioning properly like a

The cerebrum makes up three quarters of the brain. In the cerebrum, there is the ability to problem solve, move, think and feel (“Alzheimer’s Disease,”n.d.). The cerebrum can be divided into two halves, the right hemisphere and the left hemisphere. Each hemisphere has four lobes, occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Each lobe has specific tasks. For example, the occipital lobe is responsible for visual images.

The topic of brains scans, drug use and teenagers has been of much interest to many experimenters. Drug use can be defined as continues use of alcohol, illegal drugs or the misuse of over-the-counter drugs or prescription drugs leading to negative consequences. This is done by the use of brain scans, including MRI scans; also know as magnetic resonance imaging. This type of brain scan allows scientist to see detailed images of the organs and tissues within your body by a technique that uses a magnetic field and radio waves. The magnetic field temporarily realigns hydrogen atoms in the body and is able to show brain activity. The main point of this type of study is to help predict what a teenagers drug use problem will be, if any, before it

The Oxford Dictionary defines the brain as an organ of soft nervous tissue contained in the skull of vertebrates. This part of the body has three important features. These features help the brain carries out its functions. The three important features are the cerebrum, the cerebellum, and the brainstem.

The brain is the center of the nervous system; it receives information, interprets the information and guides the body’s response to the information. Three parts of the brain are the cerebrum, cerebellum, and the diencephalon, along with the brain stem. The cerebrum is the largest part of the brain which handles memory, speech, the senses, emotional responses and much more. Below and behind the cerebrum, attached to the brainstem is the cerebellum. This part of the brain controls our motor functions, ability to balance as well as our ability to interpret information sent to the brain by the eyes, ears and other sensory organs within our body. The brainstem plays as a connector; it connects the brain to the spinal cord which runs down the neck and back. To stay alive your body needs to breathe in air, digest food and circulate blood; the brain stem also acts as a charge to get these functions going. Inside the cerebrum we have the diencephalon, which is also above the brain stem. Sensory function, food intake control and the body’s ability to sleep are the jobs of the diencephalon. A traumatic injury to the brain such as a massive blow or violent shake can cause any of these functions to malfunction which is called a concussion.

With the advancement in technology, neuroimaging has led to the discovery of male brains containing a greater amount of white matter, while female brains contain more gray matter (Gur et al., 1999). Sun et al. (2015) collected imaging data to track the progress of brain network topology over a five-year period and compared the results between gender differences. Participants in the study included 43 males ranging from ages 22-53, and 28 females from ages 21-59. Only those having no brain disorders, mental illnesses, substance abuse, or first-degree family members with mental illnesses were included in the research. Twenty-eight subjects completed the study and received scans over 5 years. The results supported findings from previous

For an extended period in our history, the medical community believed that the brain was different than other organs in the body, in that it did not have the ability to repair itself. In this TED Talks presentation, Chandran (2013) discussed the recently discovered fact that the brain is able to repair itself. This is an exciting revelation, as there are over 35 million people currently living with untreatable brain diseases, creating a global cost of $700 billion annually (Chandran, 2013). Furthermore, as Chandran argued, we are primarily seeing these disorders in the aging community, and since we are living longer, the number of people with these diseases is rising. With these staggering numbers in mind, he wonders why the medical community, with all its advances, has not found resolutions that would successfully treat these diseases.

The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).

The human brain is the direction for the nervous system. The brain tells the human what to do such as, it receives the input from the sensory organs, and then sends output to the muscles (Lewis, 2016). The human brain has responsibilities in the body just like the other organs, but has its own duties to maintain (Lewis, 2016). However, the human brain makes up 2 percent of the human body weight (Lewis, 2016). The cerebrum is the largest part of the human brain, and is branched into two different hemispheres (Lewis, 2016). Individuals also call the two the left and the right hemisphere. The brainstem is located underneath, and the cerebellum sits behind it (Lewis, 2016). The human brain is also divided into three different sections which is known as the forebrain, midbrain, and the hindbrain (Lewis, 2016). Each of the sections have something in common which is fluid-filled cavities called ventricles (Lewis, 2016). There are still more pathways in the future that need to be explored to clearly under the human brain.
