Brain damage

complex rewiring of the brain is damage caused by excessive internet use. Equally important, the internet has a negative effect on how an individual think’s, read’s and retains information. The internet’s relevance to reading also has an impact on rewiring the human brain. Human beings brain’s neural networks are changing with reading in the course of the internet. Secondly, along with the internet rewiring the brain, the amount of time spent on the internet causes the brain to remember less.…

in a whole group of degenerative brain diseases in adults especially the elderly. These diseases include Alzheimer's, Parkinson's disease, Huntington's disease, ALS and more disorders of the nervous system. What all these diseases have in common is a slow destruction of brain cells that are specifically sensitive to excitotoxin damage. For example, disorders such as strokes, seizures, migraine headaches, ADD, ADHD, and even AIDS dementia have been linked to damage from excitotoxins and there is…

disease (AD). Physiologically, AD involves damage to brain cells and their eventual death. It is a progressive and irreversible disorder with no identifiable treatment or real understanding of the mechanisms and molecular determinants involved in the disease process. A majority of the destruction that occurs in AD takes place in parts of the brain that are vital for memory, such as the cortex. In addition, AD is characterized by additional changes in the brain. These include the formation of…

The nervous system holds the main organ in the body that is responsible for running and regulating the entire body; the brain. Along with all other parts of the nervous system, the brain coordinates all bodily functions. The nervous system is divided into two main parts: the central nervous system, the brain and spinal cord, and the peripheral nervous system, all extending nerves and sensory receptors. The central nervous system sends out impulses in response to…

Many people believe that human reality and experiences are the direct outcome of people’s senses and people’s reality and personal experiences are created that base on the reactions with surrounding’s stimulates. However, the production of people’s reality and personal experiences is a very complicated process, the surrounding’s stimulates are just part of it. In “The Mind’s Eye: What The Blind See” Oliver Sacks talks about the different characteristics that the blind people have and he points…

on the brain and body because it increases the synaptic levels of dopamine, serotonin (5-HT), and norepinephrine and has adrenergic agonist effects. It affects the entire body through the loss of hair, to irregular heartbeat, and finally to involuntary muscle spasms. Meth is metabolized through the liver and excreted with the use of the kidneys. The half-life of the drug ranges from 6.4 to 15 hours. When someone uses a drug the drug hijacks the reward-reinforcement pathway. Our old brain which…

Multiple sources of evidence have shown that pain perception (which is the conscious awareness of pain by the brain) is not entirely dependent on physical injury (physical injury is defined as damage to the body). This essay will consider information relating to phantom pain, battlefield injuries and referred pain as well as discussing the gate pain theory put forward by Melzack and wells. The human body has two separate pain pathways, one of which is involved in pain perception while the other…

Descartes believed that the mind controlled the brain through the body, “he placed the seat of the mind in the brain and linked the mind to the body” (Ellison 4). This concept has greatly evolved over the past few centuries; however, Descartes’ original theory created a foundation for regarding the relationship between the two. Different mediums portray this mysterious relationship between the mind and the brain in distinctive ways. The novel Andrew’s Brain by E.L. Doctorow, the essay “The Last…

Neuron-imaging techniques allow the researchers to learn about the brain structure and functions. This will help them to understand the difference and the relationship between cognitive process and behavior. There are different types of brain imaging technologies: PET- Positron Emission Topography, MRI- Magnetic Resonance Imaging, frMri- functional Magnetic Resonance Imaging EEG: Electroencephalogram and CAT- Computerized Axial Tomography. The brain imaging technologies are used in different…
