Brain Drain Essay

Thesis: What is significant about being a neurosurgeon? A neurosurgeon is a medical specialist who performs diagnosis or surgical treatment relating to the brain and the spinal cord. They treat disorders such as: acoustic neuroma (a benign tumor of the hearing nerve), angiography (imaging of blood vessels using a certain material for better visualization of vessels), anticoagulant (a medication that prevents coagulation of the blood), etc. To be a neurosurgeon, one must acquire the following…

performing two or more task simultaneously, you’re not getting the full input on both tasks that you are performing 100 percent. Research shows we have a left side and right side to our brain and when combining more then one task at a time into the brain, can lead to physical and mental effects. Multitasking drains the brain and exhausts the mind, and, if left unchecked, criticize us to early mental decline and decreased incisiveness. Becker, Mark W.Alzahabi, ReemHopwood, Christopher J.

understand the causes and how it affects the body, the symptoms, and the exams/tests and treatments for it. Unfortunately the cause for myelomeningocele is unknown, but it is believed that low levels of folic acid, which is an important part of the brain and spinal cord development, in a woman’s body before and during pregnancy plays…

the brain. The neural tube is a narrow channel that folds and closes during the third and fourth weeks of pregnancy to form the brain and spinal cord. Encephalocele is a sac-like protrusion or projection of the brain and the membranes that cover it through an opening in the skull. Encephalocele happens when the neural tube does not close completely during pregnancy. The neural tube is a hollow, embryonic structure that gradually develops into the central nervous system, comprising of the brain…

as a “set of tools that produce pictures, of the brain, sometimes called brain scans” (). There are two specific types of neuroimaging: functional and structural. Functional neuroimaging looks for brain activity by measuring the amount of oxygen that changes in the blood, electrical impulses or chemical activity. Structural imaging generates pictures inside of a head, that includes pictures of bones, brain tissues, blood vessels and fluid of the brain and spine. Neuroimaging are used by…

Drugs are chemicals that affect the brain by tapping into its communication system and interfering with the way neurons normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. Drugs that enter the blood stream have faster and definitely more intense effects. The more directly the drug enters the bloodstream determines how fast and intense the drug will take effect.…

1.1 Overview
 CSF definition It is a well-known fact that the brain lies within the skull and the spinal cord lies within the vertebral column. Between the soft neutral tissues and the bones that house them are three types of membranous coverings called meninges. Some of the space between these coverings is called subarachnoid space and filled with clear and colorless fluid (cerebrospinal fluid “CSF”). CSF circulates inside the central nervous system through the ventricular part of this system…

Methamphetamine and its Effects on the Body and Brain Methamphetamine (n-methyl-1-phenyl-propan-2-amine) has a molecular weight of 149.237 g/mol and is an addictive man-made stimulant affecting the central nervous system (Methamphetamines: An Overview, n.d.). There are two different types of methamphetamine: l-meth (Levo-methamphetamine), and d-meth (Dextro-methamphetamine), which is the more common form. It is 2 to 10 times as physiologically active as l-meth (Crystal Meth Facts, n.d.).…

hearing, vibrations travel through the three parts of the ear until they reach a portion of the inner ear called the cochlea. The cochlea resembles a snail’s shell and is responsible for converting vibrations into nerve impulses which can be sent to the brain and interpreted {4}. The fluid caused by glue ear affects this process as it dampens the vibrations and stops the ear drum from moving freely, so sounds cant be carried to the inner ear as well as usual.…

Case Study #1 Spina Bifida Q1. What is the main pathology for this disease? Who primarily gets it and why? Spina bifida is considered a neural tubal defect (NTD) that affects the spine. (1) The neural tube is formed in the very early stages of pregnancy, specifically beginning in the third week.(2) The process of neural tubal closure is very complex and it can be disrupted.(2) When the backbone fails to form or close completely, spina bifida is the result.(1) This lack of closure can…
