...Reference to REM-OFF Neurons In Locus Coeruleus” (Pal & Mallick, 2007), was researched in the study section of this unit and is discussed, as it relates to neuroanatomical structures. The reading stated that GABA is an amino acid, and denoted as the most important inhibitory neurotransmitter in the brain (Carlson, 2013). Additionally, GABAergic can work on several areas of the neuroanatomical structure, for example, in the pontine reticular formation, where GABAergic REM-on Cells works with other neurons in ventrolateral preoptic area (VLPO) to inhibit monaminergic transmission (Carlson, 2013). Sundström Poromaa et al., (2003) support this view when they describe the GABA neurotransmitter as; “the GAGAergic system is a ubiquitous and primary mediator of inhibition the nervous system” (p. 24). Next, the two types of GABA neurotransmitters are discussed, as they relate to the reading in the next paragraph. From the literature review, two types of the GABA receptors were described, which are GABAB receptors and GABAA- receptors (Sundström Poromaa et al., 2003). Those two types of GABA receptors coincides with the reading in regards to ionotropic receptors, where the neurotransmitter directly produces a rapid opening of ion channels through the membrane, as well as a rapid ending (Carlson, 2013) or GABAA, as described in the article (Sundström Poromaa et al., 2003). In addition, the reading also submitted that metabotropic receptors in contrast to the ionotropic action, are indirectly...

...Nadia Hamed English 11 CP Mrs. Martin 1 October 2012 Juvenile Justice Juveniles should not be charged as adults, because their brains aren’t fully developed and they’re legally not an adult till the age of 18 by law. Personally I think that kids shouldn’t be punished as adults. There are a lot of evidence and arguments against my theory, but I strongly believe that kids are kids and don’t deserve to be treated like adults when it comes to being put on trial. “Studies show that one-third of the level to thirteen year olds studied and 20 percent of those fourteen or fifteen year olds had levels of reasoning and awareness comparable to those of a mentally ill adult judged not competent to stand trial” (krikorian 2). To farther explain “In recent teen-brain research is the finding that a massive loss of brain tissue occurs in the teen years” (Thompson 4). My belief is no matter what crime you committee, you should get the consequences you deserve. A kid under the age of 18 isn’t considered an adult in which case they shouldn’t be charged as one. If you really think about it, It’s insane to execute 15, 16, or even 17 year old minors. It’s just absurd. Another good piece of evidence is that “The brain is like a puzzle, and growth is fastest in the exact parts the kids need to learn skills at different times” (Thompson 6). A human brain is a bit tricky, just like the law. When a human being is first brought to life is when their brains start to develop till the time when...

...Parkinson's is progressive, meaning the signs and symptoms become worse over time. Although Parkinson's may eventually be disabling, the disease often progresses gradually, and most people have many years of productive living after a diagnosis. We will be going through the organ system Parkinson’s affects as well as the signs, symptoms, and treatements. Organ System Affected With Parkinson’s The major organ system affected by Parkinson’s is the nervous system. The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis. Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves, and ganglia. These, in turn, consist of various tissues, including nerve, blood, and connective tissue. Together these carry out the complex activities of the nervous system. The various activities of the nervous system can be grouped together as three general, overlapping functions, sensory, integrative, and motor. Functions of the Nervous System Millions of sensory receptors detect changes, called stimuli, which occur inside and outside the body. They monitor such things as temperature, light, and sound from the external environment. Inside the body, the internal environment, receptors detect variations in pressure,...

...he function of nervous system is to coordinate the activities of our body. It is the control system for all our actions, thinking and behaviour. The nervous system helps all other systems of our body to work together.The nervous system is like a manager inside our body. Its job is to control and coordinate the parts of our body so that they work together, doing their job at the right time. Our nervous system coordinates muscles so that we can do things which need thinking like reading, writing, cycling or dancing. The nervous system also coordinates things which we don't have to think about, like heart beat and breathing. The human nervous system receives information from the surroundings, processes it, interprets it and then responds accordingly. The nervous system also passes information from one internal system to another. For example, as soon as we put food in our mouth, it immediately causes the release of saliva from the salivary glands. The Unit of Nervous System: Neuron : The units which make up the nervous system are called nerve cells or neurons. So, neuron is the structural and functional unit of the nervous system. We can now say that nervous system is made of special cells called neurons. Neuron is the largest cell in the body (which looks like an electric wire). Neurons contain the same basic parts as any other animal cell but their structure is specially adapted to be able to carry messages over large distances in the body quickly. The neurons carry...

Number of words: 1,608 Source Material: Garfield by Jim Davis at gocomcs.com (http://www.gocomics.com/garfield/2011/08/12) All rights reserved to Jim Davis Garfield, a normal house cat, lives with his owner, Jon, and constantly have talks between each other. Yet, in this comic shown, there is a question derived from the knowledge of what Garfield can do, and that is if animals could be a person. The obvious answer to any average human would be 'No', but only by means of distinguishing between a normal household cat and a human and only comparing the physical body structure of both. After all, Garfield is supposed to be a normal household cat. But, he may have that human personality, because he thinks and it is somewhat of a communication with Jon. He also stands just like a human, and has a background for drinking coffee out of a mug, making him somewhat of a person. Yet this comic, depicting him as Jon's kid only for the practice of having kids, only describe the topic of believing that animals could be persons. Garfield is fat tabby cat that has a big attitude between him, Odie, a dog also in the house, and Jon. Yet, throughout the comic series, Garfield also struggles with human problems, such as diets, loathing of Mondays, apathy, boredom, and working out. Most of the time, Garfield is found either with himself or Jon in a conversation speaking through thought...

...Music is unique to human beings. We are the only species on earth capable of making and comprehending music. It has existed since the early stages of human life; it is believed that music was developed before language and speech. It has the power to change our moods and behavior, as well as affect the way we go about the things we are simultaneously doing. Music is constantly changing and evolving, and many times it shapes our current culture. There is argument over whether the music nowadays has a negative effect on America’s youth. Hip-hop takes the blame for many social problems in America, however many people overlook the influence it has and are unwilling to learn what it is about. Music, and more specifically hip-hop, has a positive influence on people and our culture in several different ways, including the way it affects the human brain, and the way it shapes and changes our culture and society as a whole. Music has an effect over people on a neurological level, which goes unnoticed by many. Music makes the human brain operate and can be beneficial at very early stages of brain development. Music helps immensely in learning and memorization; babies can even speed up their auditory comprehension due to musical exposure. Adults speak slowly to babies, annunciate syllables, and emphasize the pitch of their voice according to whether they are saying a demand or a question. For example the pitch of your voice goes up when asking a question and goes down or stays even throughout...

...Karis Hayden Cassendra Russell PSI 120 25 January 2010 Brain Plasticity Brain plasticity is a term that sounds so odd to most of us. The term itself is the process of the human brain being able to change for better or for worse throughout life. Jodie was a young girl whose brain started changing rapidly. Her right hemisphere was not working the way that it was supposed to resulting in her losing the ability to use the left side of her body. She also started having seizers at a young age. She underwent a surgery that’s outcome would be to live the rest of her life with only half of her brain. This outcome to most people is shocking. My first judgment was that it was impossible. After watching this clip I was amazed at how the brain, or rather the human body is able to adjust to such drastic changes. In the clip Dr. Benjamin Carson stated “Human beings are incredible creatures with a brain that is beyond belief in terms of its capabilities; to the point where we can take half of it out and still function in a normal way.” Once she had gone through the surgery she was able to walk out of the hospital within 10 days. That is amazing that such a young girl can go through that and still be living a normal life. Of course after the physical change there are several changes that happen to the body, but because of the plasticity she was ambulant. The reason she is able to be functioning is because of plasticity which is when the brain changes shape creating new connections between...

But somewhere between the presentation and the next day's business, that resolution disappears more quickly than doughnuts at a Monday morning meeting. Don't despair: It's not you; its your brain. And you will find solace in learning that there are scientific explanations for why you didn't act on the speaker's advice, as well as for many other perplexing human behaviors. Why do people only retain a fraction of what they leam? Why do they get a boost of energy when their bosses meaningfiiUy praise their work? Wliy do they tire when focusing on one activit}'? Once mere speculators about the hows and whys of human response, cognitive scientists are discovering what happens in the brain to cause such reactions. And as neuroscientists continue to study why humans do the things they do, human resource professionals can turn that knowledge to practical use in the workplace. The joining of psychologj' (the study of the human mind and behavior) and neuroscience (physiological study of the brain) sheds light on the brain's role in human nature and behavior.

Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. The ways neurons communicate are through electrochemical process. Chemical messages are sent from one neuron to another through its dendrites. Once a message has been received by a neuron it changes electrically. This rapid change is called rapid potential, also known as nerve impulse. The impulse travels from the beginning of the axon to the terminal buttons that are located at the end of the axon. This process causes neurotransmitters to release which allows messages to reach the next neuron. The site where the nerve impulses transmit from one nerve to another is called synapse. Neurons are separated by a gap called the synaptic cleft. This is located between the terminal buttons at the end of the axon. All messages must past this cleft. There is a neuron on each side of the cleft. The one that sends is called the presynaptic, and the receiver is the postsynaptic neuron. Inside the presynaptic...

...The Science of Psychology Foundations of Psychology Suzette Lee [ Monday, April 02, 2012 ] PSY300 Psychology is a scientific study that investigates the main components of the brain, the mind and the body in different fields of psychology in order to understand and conduct observations of the mental process of the human mind, and observable behavior. Psychology is often used to understand the unknown of human behavior, and their potential patterns that observe the actions of self expression on how people feel and store memory. The study of the mind is an observation of a person’s mental awareness of both the conscious and unconscious mentality. Structuralism was the dominant school of psychology in Germany and the U. S. between1890-1920, and was the school of thought based on the notion that the object of psychology is to analyze consciousness into its basic elements and investigate how these elements are related. Structuralism explores areas of the mind, focus mainly with sensation and perception in vision, hearing and, touch through introspection, or the systematic observation of one’s own conscious experiences, although Functionalism was the protest against structuralism and had the assumption that functionalism was more practical and concerned with commonsense issues, structuralism believed that mental functions were not subject to introspective analysis which it was the shaping of the mind that could be analyzed. Another school of thought is behaviorism, in which...

...-IBM simulates 4.5% of the human brain - Skynet and Terminator next? Source: http://features.techworld.com/applications/3313898/ibm-simulates-45-of-the-human-brain--skynet-and-terminator-next/ Author: Jason Kennedy Date: October 27, 2011 Summary: The article describes how latest research by IBM shows that computers may soon be able to match human brains. When it comes to storage, machines have long surpassed human’s capacity and in terms of mathematics, fast computers beat us by far in solving complex equations. However, (at least until now) humanity wins in the brain’s sheer computational power and energy efficiency. IBM’s Blue Gene supercomputer has already outclassed the processing power of some animals like mice, rats and cats. Of the 20 billion neurons and the connecting 200 trillion synapses the human brain contains, IBM’s Blue Gene simulated about 4.5%. By 2019, the company is confident to have equaled the processing power of one entire human brain. Analysis: Certainly this topic puts a lot of people on edge. We may all have heard about Moore’s Law of computers suggesting that a PC’s processing capacity will drastically increase over the years but the fact that our society may reach a point where computers are intelligent enough to make themselves smarter through repetition and design, and eventually outperform humanity is intimidating and needs to be discussed. Like we talked about it in class, where will this lead to? Will we experience a real-life...

...of the nervous system. Neurons are found to be very close to one another forming a network of neurons. Neurons never touch and the way they communicate with each other is called a synapse. The synapse transmits information chemically between the neurons and cells they are trying to reach. Neurotransmitters are released from the neurons to activate receptors in other cells thought out the target cells. Drugs on the other hand interact with the receptors in the neurons and the target cells either activating them or blocking them, and then the drug has the effect the user wants. The neurotransmitters of the brain come in different variety and have different effects on the body. Acetylcholine is found in large quantities in the brain. It can have an inhibitory effect on the person causing euphoria and insomnia. Acetylcholine derived mostly from nicotine which is found in cigarettes. Catecholamines are neurotransmitters that include norepinephrine, dopamine, and epinephrine. These neurotransmitters control thought process. Cocaine for instance blocks the reuptake of dopamine and norepinephrine which cause increased feelings of agitation and paranoia. This caused by the simulation of non-catecholamine’s in the brain. Serotonin is a neurotransmitter that is found in most foods and other things we eat or drink. Serotonin results in the feeing of relaxation and is used for sleeping problems. The abuse of drugs can have a negative impact on the user; a change in the serotonin system can cause...
