Brain Drain Essay

In the United States the Amyotrophic lateral sclerosis is sometimes called motor neuron disease. Also known as ALS this disease causes the nerve cells to gradually break down and die. Amyotrophic lateral sclerosis is known to be a progressive degeneration of the nervous system disease. Which causes muscle weakness and the impact of physical functions. The ALS often begins by the twitching of a leg or arm or the weakening of muscles. In other cases it also begins by the slurring of speech. This…

From evidence gathered in the above studies, it is clear that if children are actively engaged in learning music, there will be quantifiable changes in areas of the brain used when playing music such as the auditory and motor cortices. These changes are sustained into adulthood as seen in adult musicians who have continued to use the skills they learned as a child and benefit from the increase in size and connectivity of regions critical for playing music. It should also be noted that in all…

g a description of origin, course, and termination, as well as an explanation of how they relate to LMNs. Motor commands generated in the CNS travel on upper motor neurons (UMN) and synapse with lower motor neurons (LMN) to send messages to the muscles of the body. UMNs are first-order neurons, they do not leave the central nervous system. The pyramidal and extrapyramidal tracts consist of UMNs. Since UMN do not leave the neuraxis they have to synapse with LMN to carry messages to the muscles.…

stimulating the way of certain brain chemicals like listening to music increases the neurotransmitter dopamine. What is dopamine? “Dopamine is the brain’s “motivation molecule” and an integral part of the pleasure-reward system.” Like when you listen to your favorite song it triggers a small dopamine boost which gets you feeling excited. Music can be used in various of ways it can put your moods from sad to feeling relaxed. It does all sorts of things to our brain and body that we don’t know. In…

Why is spinal cord injury considered an orphan disease? It affects a relatively small amount of people How do functional abilities differ in quadriplegia and paraplegia? Quadriplegia occurs when there is a spinal cord injury in the neck. It affects the sensory and motor information going to all four limbs. If the injury occurs in the thoracic spinal cord, the arms are okay but the patient is paralyzed from that point down. That is called paraplegia. Both quadriplegia and paraplegia can be…

defensive wars could never be fortified” (Steinbock 66p) “Ashley, called the “pillow angel” by her parents, suffers from a developmental brain condition known as static encephalopathy “(P Clark). When I did research about this case I find out the exact type of brain damage Ashley has. “Static encephalopathy - permanent brain damage or dysfunction. A lack of oxygen to the brain, such as when a fetus is exposed to alcohol in the womb, is one of many causes of this type” (Kivi). So, is this mean…

Reviewing the article titled A Brief History of the Lobotomy by Dr. C. George Boeree, gave much insight into the gruesome history of lobotomy. As many know, lobotomy is a neurosurgical procedure in which nerve pathways in a lobe or lobes of the brain are severed from other areas in order to terminate contact and improve ones mental health condition. This theory developed in 1890 when a German researcher, Friederich Golz, removed portions of his dogs’ temporal lobes and noticed a change in…

Farsightedness or being farsighted is when you see far, but you can’t see near objects clearly. The 130 receptor cells are also known as rods and cones. The Central Nervous System is apart of the Nervous System, but the Central Nervous System makes up the brain, spinal cord, and retina. The Nervous System is a collection of nerves and cells called neurons. Neurons can transmit signals to and from different parts of the Nervous System has two main components the Central Nervous System and the…

Nerves Introduction The cranial nerves are important nerves in our brain and they are located on the bottom surface of human brain. They are twelve pairs of nerves. Some of the cranial nerves are responsible to control body muscles, some of the cranial nerves are associated with the internal organs or glands such as human heart of lungs and some of the cranial nerves are responsible to take information from the sense organs to the brain. A list of these nerves is given below with a detail of…

Your two-year-old is standing in front of you and you are really, really angry at her. How can we find this little itsy-bitsy person dangerous? And yet we've all done it (or is that just me?!) Our safety brains go too far. What about your mother-in-law from hell; how can you find her dangerous? (OH YEAH, that's different! NO it's not - but it might take longer to get there!) If your difficult person gets along with others, even one or two others, but not…
