The Brain: The Most Complex Organ In The Human Body

“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

I started my education in Erie, Pennslyviana.I attend McDowell High. I would say that we were one of the richer schools were I live. I am going to talk about my first assignment Brainology. I thought it was very interesting and it thought me a lot about how some people have different mindsets.

Q1: The cerebral cortex is a highly organized, six layered structure (L1-6) with a variety of excitatory and inhibitory cell types. Excitatory (glutamatergic) neurons make up 80% of the cortex and consist of pyramidal and spiny stellate (granule) neurons. Inhibitory (GABAergic) neurons make up only 20% of the cortex and consist of four different subtypes: non-fast spiking serotonin expressing GABAergic neurons, martinotti cells, basket cells, and chandelier cells (Petersen & Crochet, 2013; Shipp, 2007). The total number of neuronal cells in the adult human cortex is 21.4 billion for females and 26.3 billion for males; however, there are also non-neuronal cells present in the cortex (Pelvig, Pakkenberg, Stark, & Pakkenberg, 2008). The major non-neuronal cells are glial cells and consist of: oligodendrocytes (75% of non-neuronal cells), astrocytes (20%) and microglia (5%) (Pelvig et al., 2008). The layering of the cortex is highly organized, with specific cell bodies located in each layer. Layer 1 receives input from other cortical layers as well as subcortical layers and is comprised solely of inhibitory neurons, although there are axons and dendrites that project onto these neurons in addition to non-neuronal cells (Petersen & Crochet, 2013). Layers 2/3 are difficult to differentiate from one another, and often referred to as the supragranular layers. These layers contain medium sized pyramidal cells that have densely packed and highly aligned apical dendrites and make

As we all know, the human brain is the most insubstantial and vital organ in the human body as it is the command center for every other body part (newscientist.com). Any slight wound to this organ could lead to severe consequences usually encountered at that very moment. It may be an extremely low chance of a major head injury, but it does happen to millions of people annually. One single concussion, provided with the lack of healing, could lead to short-term and long-term memory loss, depression,

When it comes to the topic of having a growth mindset, most of us will readily agree that students who are praised are motivated to learn. Where this agreement usually ends, however, is on the question of how they are praised. Whereas some are convinced that praising students for their intelligence will motivate them to learn, others maintain that encouraging them for their efforts has a better impact on their motivation.

I have always had a passion and interest in working with the unknown. When I was in high school, I always made sure I was taking science classes that interested me, and would help me decide on what I wanted to major in college. I chose neuroscience as my major because it is a subject that continues to fascinate me. Neuroscience is the study of how the nervous system develops, its structure, and what it does. I want to focus on the brain and its impact on behavior and cognitive functions. I want to go into clinical neuroscience (looking at the disorders of the nervous system) or cognitive neuroscience, which studies the higher cognitive functions and underlying neural bases. With a neuroscience major, I would like to pursue a career in clinical research, do research for the National Institute of Health, work for the CDC and specialize in neurological disease, and/or run a clinical research project in another country. I want to pursue a career in one of these areas because I want to dedicate my knowledge, skills, and time to helping people and the world of science. I want my work to make a positive impact on society and be beneficial for the forthcoming generations. I want to help people and discover new things that will help those in need. I am motivated every day to continue working hard by realizing there are still more things to be discovered and that it could be done by me.

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.

As mentioned before the human brain is the most complex organ in the body that is made up of many parts. The areas of the brain that our most affected by substances use include: the brain stem, cerebral cortex and the limbic system. The brain is responsible for all human activity- thoughts, behaviors, walking,

One part of the brain is the Brain Stem. It control the heart rate, blood pressure, and breathing. The brain stem also consists of the medulla, midbrain, and the pons. The medulla controls the body functions. The midbrain regulate body movement, hearing, and vision. The pons controls the posture, movements, and sleep. I would hate to have this part of my brain damaged because it controls some of the most important parts of my body such as my heart. It can cause behavioral impairments.

In order to better understand the neurological complexity of the human brain, it is reasonable to first compare it to a similar organ, and according to Professor David Anderson, that is a fruit fly 's brain. As a neurological researcher at the Caltech David Anderson Lab, Professor Anderson claims that the human brain is much more complex than thought, but with the help of fruit fly experimentation, understanding the human brain is made simple. As guest speaker at the TED Conference, Anderson informs his audience of a common misconception with the human brain, a misconception he intends to disprove by using evidence from his fruit fly experimentations.

To deal with the problem of dysfunctional families, Vance proposes a solution of stable family. The author’s grandmother took the decision that he will live with her to have a stable family environment which he was not getting from his parents. This stable family bonding helped him a lot in succeeding in his life. It helped him in his studies as well as in his social life. He was very satisfied from the home environment and thus able to concentrate all his attention towards his studies and positive behavior. Later when he was married, he formed a stable bond with his wife and stated that he is leading a better and happier life.

Brain is highly metabolic and important organ of the body. Even though it weighs only 2% body weight, however, requires disproportionate amount (~20 %) of the total blood flow. Unprecedented fall in cerebral blood flow (CBF) would quickly lead to unconsciousness and, if sustained for longer period of time would result in brain damage and death. Therefore, CBF is tightly regulated in the brain, as it facilitates the delivery of essential substrates required for metabolism and removal of metabolic by products.

The significance of this video’s phenomenon is that it assists people learn what kinds of conduct can help protect themselves to acceptably fit in their civilization making them into, “instinctive copycats and for a really good reason: survival… as deep in the brain…we got special cells known as mirror neurons” (H. C. Sinclair, 2013). It also relates to current human behavior for the reason that it echoes the modeling or imitation behavior executed by children and adolescents. For example, individuals that are into Football will get worked up from just watching it due to similarly reacting to the responses of the actual audience at the game. The reason as to why is because of the outcome of the human brain’s premotor cortex initiating its mirror neurons via trying to mentally-mimicking the same movements communicated by their facial expressions. Ultimately, the simulation of these neurons on a cellular level is fundamental for humans to effectively comprehend the feelings of others or empathize that can straightforwardly be influenced without their knowledge such as the case of advertisers that earn millions each year from making use of this unique wiring to their advantage.

Psychologists are constantly researching the what, when, why, and how of various behaviors of people. One of the more popular topics in this field is memory and the different components involved in false memory in humans. A false memory occurs when a person recalls an event that never happened, or remembers an event differently from the way it happened. For the most part, our brain is a reliable source, but it does contain errors and it is easily tricked. There have been times where I have locked my car, walked into class, and forgot whether I locked my car or not within about a five minute time span. The human brain is complex and highly compartmentalized. Information is consistently getting filtered and filed away into different sections

the human brain can be burdened with various diseases and disorders. Since the brain acts as the bodies control system, any malfunctions can result in serious problems to the entire system, including memory, sensation, and even personality; factors such as illness, genetics, and trauma are a few of the main things that cause Brain disorders. (Brain Disorders) Degenerative diseases, psychiatric diseases, brain tumors, brain injuries,and addiction are some major illnesses that come into play. Degenerative diseases are passed down through generations; an enormous forty five million people are affected by these conditions, all across the world. Alzheimer's, ALS, huntington's, and parkinson's disease are all categorized as degenerative diseases. Depression, schizophrenia, and bipolar disorder are classifies as non other than psychiatric disorders; luckily, these disorders can be treated with therapy. There is a variety of auspicious options that can be chosen from accordingly for the patient. Additionally, many individuals suffer from addiction; while everyone is at risk of addiction in some way shape or form, a few are at higher risk than others. When a person is suffering from this dreadful condition, they do not think rationally, and tend to act upon impulses; the craving is at such an intensity in some cases, that the individual is willing to put everything at risk, and disregard whatever the consequences may be. Biologically, the chemical makeup and structure of the brain itself undergoes alterations under the circumstances that the individual repeats his or her use of drugs. By exciting the nerves within the reward center of the brain, the recipient experiences a feeling of thrill themselves. (Brain Facts) When a brain undergoes a serious blunt trauma, There is a high chance that brain tissue, neurons, or nerves could have been severely ravaged, and this may lead to a variation of negative conditions; hematomas, blood clots, contusions (bruising of the brain tissue), concussions, strokes, and cerebral edema (swelling within the skull of a person) are all high on the list of disorders caused by injury to the brain. The ability to connect with the rest of the human body may be very distorted, therefore,
