Inhibitory or Excitatory Potential Changes
"MDMA affects the brain by increasing the activity of at
least three neurotransmitters (the chemical messengers of brain
cells): serotonin, dopamine, and nor epinephrine" (The Brain's
Response to Hallucinogens). This increase in activity can be
either excitatory or inhibitory in nature depending on the
neurotransmitter involved and which part of the reaction to the
drug is taking place. Every area of the brain containing
serotonin, dopamine, and/or norepinephrine is affected by MDMA,
but the serotonergic and dopaminergic pathways are principally
affected. This includes the neocortex and much of the limbic
system. Within the limbic system, the hypothalamus, basal
ganglia, amygdala, and hippocampus are affected. In the reward
center, the nucleus acumens, a place where dopamine neurons are
prevalent, is affected (Hallucinogens).
In each part of the brain, action potentials or inhibitory
responses to MDMA cause the side effects felt by users. The
neocortex is responsible for memory and altered perceptions,
while the limbic system influences changes in moods, emotions,
and feelings of anxiety. The hippocampus is also responsible for
memory, while the nucleus acumens is said to be responsible for
feelings of pleasure or the reinforcing effects of MDMA. It is
important to realize that all the pleasurable and not so
pleasurable behavioral and physiological effects of MDMA are
occurring because neurons within the cell bodies of our bodies
are reacting to the foreign stimuli.
When MDMA crosses the blood brain barrier it begins to
affect presynaptic neurons containing the neurotransmitters
mentioned. It causes repeated EPSPs in addit...

...ne neurons and send signals
directly to these dopamine neurons" (Ecstasy 16). This means
that serotonin can stimulate the release of Dopamine into the
synapse and does so when MDMA creates an action potential that
causes the release of serotonin.
MDMA has an inhibitory affect on the neurotransmitter
Norepinephrine as well. Norepinephrine terminals are involved
with the uptake and removal of Dopamine from the synapse
(Yamamoto 274). The Nucleus Acumens is affected when MDMA
prevents the reuptake of Dopamine by the Norepinephrine
terminals. Norepinephrine is found in the basal ganglia as well.
The excitatory and inhibitory effects of MDMA on neurons and
neurotransmitters are numerous. The important thing to remember
is that axons of serotonin are far reaching and affect many
areas of your brain and body that you might not have considered.
As Inada points out with his analogy to a constellation, the United States government had constructed many camps and scattered them all over the country. In other words, the internment of Japanese-Americans was not merely a blip in American history; it was instead a catastrophic and appalling forced remov...
What were the Japanese internment camps some might ask. The camps were caused by the attack of Pearl Harbor in 1942 by Japan. President Roosevelt signed a form to send all the Japanese into internment camps.(1) All the Japanese living along the coast were moved to other states like California, Idaho, Utah, Arkansas, Colorado, Wyoming and Arizona. The camps were located away from Japan and isolated so if a spy tried to communicate, word wouldn't get out. The camps were unfair to the Japanese but the US were trying to be cautious. Many even more than 66% or 2/3 of the Japanese-Americans sent to the internment camps in April of 1942 were born in the United States and many had never been to Japan. Their only crime was that they had Japanese ancestors and they were suspected of being spies to their homeland of Japan. Japanese-American World War I veterans that served for the United States were also sent to the internment camps.(2)
Ten weeks after the Japanese had bombed Pearl Harbor, President Franklin D. Roosevelt (FDR) singed an Executive Order of 9066 that authorized the removal of any people from military areas “as deemed necessary or desirable”(FDR). The west coast was home of majority of Japanese Americans was considered as military areas. More than 100,000 Japanese Americans was sent and were relocated to the internment camps that were built by the United States. Of the Japanese that were interned, 62 percent were Nisei (American born, second generation) or Sansei (third-generation Japanese) the rest of them were Issai Japanese immigrants. Americans of Japanese ancestry were far the most widely affected. The Japanese internment camps were wrong because the Japanese were accused as spies, it was racism, and it was a violation to the United States constitution laws.
World War Two was one of the biggest militarized conflicts in all of human history, and like all wars it lead to the marginalization of many people around the world. We as Americans saw ourselves as the great righteous liberators of those interned into concentration camps under Nazi Germany, while in reality our horse was not that much higher than theirs. The fear and hysteria following the attacks on pearl harbour lead to the forced removal and internment of over 110,000 Japanese American residents (Benson). This internment indiscriminately applied to both first and second generation Japanese Americans, Similarly to those interned in concentration camps, they were forced to either sell, store or leave behind their belongings. Reshma Memon Yaqub in her article “You People Did This,” describes a similar story to that of the Japanese Americans. The counterpart event of pearl harbour being the attacks on the world trade
Japanese internment camps are an important part of American history. They represented and showed much of the change that happened around World War II. Although many people may say that races other than African-Americans were not that discriminated against, that was not the case. The Japanese-American People lost their homes, livelihood, and were separated from their families. More people should know about this event so as to learn from it and let something similar never to repeat it. Japanese internment camps should be an event all new American’s learn about because of its importance in World War II, the influence racism had on the camps, and for being one of the biggest violations of civil rights in American history
The federal government ruled most of the reasons behind Japanese internment camps. Further than two-thirds of the Japanese who were sentenced to internment camps in the spring of 1942 were in fact United States citizens. The internment camps were the centerpiece for legal confines of minorities. Most camps were exceedingly overcrowded and with deprived living conditions. The conditions included “tarpaper-covered barracks of simple frame construction without plumbing or cooking facilities of any kind.” Unfortunately, coal was very hard to come by for the internees, so most would only have the blankets that were rationed out to sleep on. As for food, the allotment was about 48 cents per internee. This food was served in a mess hall of about 250 people and by other internees. Leadership positions within the camp were only given to the American-born Japanese, or Nisei. Eventually, the government decided that...
In 1942 Roosevelt signed the Executive order 9066 which forced all Japanese-Americans to evacuate the West Coast. They were forced out no matter their loyalty or their citizenship. These Japanese-Americans were sent to Internment camps which were located in California, Idaho, Utah, Arizona, Wyoming, Colorado, and Arkansas. There were ten camps all-together and 120,000 people filled them (2009). The immigrants were deprived of their traditional respect when their children who were American-born were indorsed authority positions within the camps. In 1945 Japanese-American citizens with undisrupted loyalty were allowed to return to the West Coast, but not until 1946 was the last camp closed.
The internment camps were permanent detention camps that held internees from March, 1942 until their closing in 1945 and 1946. Although the camps held captive people of many different origins, the majority of the prisoners were Japanese-Americans. There were ten different relocation centers located across the United States during the war. These Japanese Americans, half of whom were children, were incarcerated for up to 4 years, without due process of law or any factual basis, in bleak, remote camps surrounded by barbed wire and armed guards.
U.T. Place and J.J.C. Smart defend the view that a sensation state is a type of brain process. The ‘Sensation-Brain Process Identity Theory’ states: For any type of sensation state S, there is a type of brain state B such that: S = B. For Place, conscious experience is nothing but a brain process. Place and Smart argue against the view that acceptance of inner processes entails dualism (Place 44). Instead they hold conscious qualities can effectively be reduced to physical processes which are conscious states. A sensation state is an inner process. Inner processes according to Place and Smart are nothing ‘over and above’ brain processes. Under their view, the experience one has when tasting vanilla is the same thing as the object undergoing the corresponding type of brain process. The ‘Brain Process Identity Theory’ argues the ‘feel’ we associate with exposure of vanilla to the tongue is identical to a type of brain process cause by said exposure. To postulate non-physical properties to explain conscious states would bear the burden of proof.
Physicalism is the position that nothing can exceed past what is physically present, and what is physical is all that there can be. This idea is reductive in that it suggests there is no more to the universe than physical matters, including brain processes, sensations, and human consciousness. J.J.C. Smart explains sensations as a means of commentary on a brain process. He believes that, essentially, brain processes and what we report as sensations are essentially the same thing in that one is an account of the other. He writes in “Sensations and Brain Processes” that “…in so far as a sensation statement is a report of something, that something is in fact a brain process. Sensations are nothing over and above brain processes,” (145). Though
What is it that makes us human? Is it our actions, our sense of purpose, or our ability to keep our mind on as well as perform complex tasks? Is it that we analyze our own mental processes, as well as the processes of others? What exactly is a mental state, and what creates it? Is it a level of attentiveness, an impulse, or an emotional state? What is it that allows us to experience these things? The answers all lie within our brains.
Ethics is the moral behavior that guides our actions; it motivates us in our personal behavior and is relevant in a business setting as well. Many organizations have set forth a set of guidelines known as a “Code of Ethics”. The Institute of Electrical and Electronic Engineers, being one of these organizations, has set forth their code as a requirement for students and engineer members to adhere to. Heading towards a career in electrical engineering I choose this organization to elaborate on for my ethics project.
Engineering ethics focuses on the behavior of the individual - the engineer, and the development of ethical standards governing their professional activities. Engineering ethics has always existed as a set of rules or a system that governs the behavior of an engineer. Among its main provisions, we can attribute such as the need to faithfully perform engineering work that would bring welfare and do not cause harm to people; be accountable for engineering professional activities; a good relationship ( customs and rules governing relations ) with other engineer, etc.
Neuroscience is a branch of science that studies the ways the nervous system and the brain work, develop, etc. neuroscience tries to understand the appearance, growth and development of neurons, along with their connections.
