Neurology: All in your Head Essay

The largest part of the brain "the cerebrum" is divided in to two hemispheres, each hemisphere have different functions and responsibilities in memory, reasoning and language. The two hemispheres are in close communication with each other via corpus callosum .

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.

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 brain is a very complex organ that researchers are still trying to fathom. “ … I DO know that scientists are working to understand HOW the brain works and are trying to figure out exactly how it is hard-wired, so they can then explain WHY we have certain reactions, develop diseases, etc.” said Ms. Buchanan. The main parts are the Frontal lobe, Central sulcus, Cerebellum, Temporal lobe, Parietal lobe, Sylvian fissure, and Occipital lobe. Each of these parts are responsible for the various movements one does, the thinking process, memory and many

The brain is one of the most complex parts of our body because it controls everything. Your brain is made up of two sides your left side and right side. The left side of your brain controls the right side of your body, and the right side of the brain controls the left side of your body. In your brain you have six different lobes each doing a different job. The Frontal lobe controls your attention span, concentration, judgment, personality

Neurology and Neurosurgery Neurology Overview Although our primary interest is with the Medial Temporal Lobe, also called the V5 area, a discussion of the entire motion perception pathway is instructive. Motion perception actually begins with the specialized visual receptors in the retina known as M-cells (from the Latin word magnus, for large). As the name implies, the M-cells are relatively large, located in the peripheral retina, and respond quickly to transient visual stimulation making them ideally suited for motion detection. By contrast, P-cells are smaller, located in the fovea, react more slowly to stimuli, and are suited to fine-detail vision.

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 Brain is made up of four key components. Firstly, the cerebrum. Secondly, the cerebellum controlling act that helps with a lot of things in the brain. Thirdly, the brain stem, which helps you breathe and much more. Also, the pituitary gland, this controls how you develop through puberty.

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

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

There are many parts to a brain, and each and every part is useful. It is difficult for people to elucidate what every single part is and what is does. Some people just think the brain is a bunch of swirls, but

“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 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.
