Brain death

Professor Batorsky WRT 101 11/30/2016 Brain Development Does the question " Why is he/she smarter than me? " brush through your mind whenever you see that someone always gets better grades than you do? Brain development is affected by certain factors that include both physiological as well as environmental. However, the influence of these factors must be equalized for maximum brain functionality. The brain is considered as many things at once by different people.…

actually worse and by how much. The problem between the two it is the fact that one is more of a psychoactive chemical. While there has never been evidence of marijuana overdose cause an incident. It has been found in alcohol to have caused many deaths just from the overdose alone. I'm not saying that and you said you either these two chemicals is perhaps perfect but there are clear indicators for each chemical that can be a positive or a negative depending on which side you're looking at.…

Parkinson's disease, also abbreviated as “PD”, is a neurodegenerative disorder that affects a person's nervous system, making them have trouble moving. A human has certain kinds of nerve cells in the brain called dopamine, these cells transmit and send signals to the brain allowing a person to control their movement. When these cells start breaking down and having problems, they cause a person to lose their control of movement, due to the lack of dopamine. PD is not a communicable disease – it…

living in a poor environment, with not as many aids as wealthier people, get the advantage of possessing causes damage or underdevelopment of the prefrontal cortex. Also, it makes the child more susceptible to contaminants such as lead which alters brain function and tends to correlate with a lower iq. These factors are not the only causes of violent behavior, but being taught and being surrounded by abusive violent people and unhealthy areas have a huge impact on it. Violent behavior takes a…

(AD) was first discovered in 1907 by Alois Alzheimer, a German psychiatrist and neuropathologist. He noticed that the brain tissue of a recently deceased woman was exhibiting strange abnormalities. Upon further examination he discovered abnormal clumps and tangled fibers; which are now known as amyloid plaques and tau tangles. Alzheimer’s disease is an irreversible and progressive brain disorder characterized by memory loss and loss of cognitive abilities. While Alzheimer’s disease was not…

throughout life, their aggregates gradually accumulate as we age. These aggregates form distinct and observable structures in the brain which generally known as amyloid deposits in the brain. Furthermore, some form of mutation increase the chance of misfolding in proteins which is the case in the genetic or familial case of NDs [22]. Though the mechanism is not clear, it has been proven that deposits of misfolded proteins are known to be neurotoxic and able to cause apoptosis in neuronal cells.…

aggressive tendencies as an adult. High levels of MAOA alone do not predispose a person to aggression, but social and physical abuse trigger the MAOA gene leading to the aggressive and antisocial tendencies. Neurological imaging of Joel Rifkin’s brain showed little prefrontal cortex activity and poor symmetry. Originally Rifkin appeared to be functioning normal with an average to superior IQ and an MRI that appeared structurally…

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…

major organs like your brain, liver, and kidney. Each organ responds different to the alcohol and causes different affects. Could you imagine living your life without a memory? Alcohol can cause that. When a female and a male drink a lot of alcohol it can cause you to have burry vision, slurred speech, difficulty walking, and slow reaction to things. According to Daniel W. Homer, A female has different affects that is alcohol related then a male. Alcohol for a female brain is more vulnerable to…

majority of all cases of dementia (Advokat, Comaty & Julien, 2014). Although the exact cause of Alzheimer’s is unknown, it is hypothesized that two systems crucial for the communication between brain cells fail due to the down regulation of acetylcholine and the over activation of glutamate, which result in the death of neurons (IOS Press, 2008). It is believed to involve the irreversible loss of cholinergic neurons, specifically in the cerebral cortex and hippocampus (Advokat et al., 2014). The…
