Psilocybin and Body Changes
Physiological (Whole Body) Changes
Psilocybin, the active psychotomimetic, hallucinogenic
chemical found in the psilocybe genus of mushrooms, is absorbed
through the mouth and stomach and is a monoamine-related
substance (Levitt 1975, Grilly, 1998). This means that
psilocybin's biochemical effects are mediated by changes in the
activity of serotonin, dopamine, and norepinephrine in the
central nervous system (made up of the brain and the spinal
cord) primarily by way of 5HT2a receptors (Grilly 1998, Hasler
2003). Monoamine-related drugs share a basic similarity in
molecular structure with monoamine neurotransmitters serotonin,
dopamine, and norepinephrine. Psilocybin produces bodily
changes which are mostly sympathomimetic. This means that
psilocybin mimics the effects of stimulating postganglionic
adrenergic sympathetic nerves (online medical). The effects of
this sympathetic nervous system arousal may consist of pupillary
dilation, increases in blood pressure and heart rate,
exaggeration of deep tendon reflexes, tremor, nausea,
piloerection (hair erection), and increased body temperature
(Grilly 1998).
Psilocybin creates distinct psychological (hallucinogenic,
entheogenic) changes in humans. Because of the mind-altering
properties of the drug, much research on psilocybin is devoted
to understanding its physiological effects on brain chemistry.
A recent study tested prefrontal activation during a
cognitive challenge and the neurometabolic effects of four
different drugs on 113 regions of interest of the brain
(Gouzoulis 1999). The four substances tested were psilocybin,
d-methamphetamine (METH), methylenedioxyethylamphetamine (MDE),
and a placebo in healthy volunteers. No significant differences
of global cerebral metabolism were found in the four groups.
Neurometabolic effects were found to include a significant
increase of regional glucose activity in the right anterior
cingulate of the brain, the right frontal operculum, and an
increase in activity of the right inferior temporal region. A
significant decrease in metabolism was found in the right
thalamus, the left precentral region and a decrease in activity
was found in the left thalamus. Overall there was a general
hypermetabolism of the prefrontal region of the right hemisphere
and hypometabolism in subcortical regions. During the cognitive
challenge activation of the middle prefrontal cortex was
eliminated and activation of Broca's area (right frontal
operculum) was reduced.
In a study conducted by A.M. Quetin, electrolyte levels,
liver toxicity tests and blood sugar levels were shown to be
ABIGAIL WAS A MINISTER’S DAUGHTER ( REV WILLIAM SMITH ) FROM THE NEARBY TOWN OF WEYMOUTH. SHE KNEW OF JOHN THROUGH A COUSIN, HANNAH QUINCY. JOHN WOULD COME TO HER HOUSE WITH HER SISTER’S (MARY) FINANCEE (MR CRANCH). JOHN AND ABIGAIL BEGAN DATING ON THE DAY THE FAMILY PLANNED HER SISTER’S WEDDING. JOHN THOUGHT ABIGAIL WAS THE MOST EDUCATED WOMAN HE HAD MET. ABIGAIL’S MOTHER, ELIZABETH QUINCY, DIDN’T THINK TOO HIGHLY OF JOHN BECAUSE SHE THOUGHT LAWYERS WERE WICKED. THEY COURTED FOR SOME TIME. MRS SMITH WAS RESPONSIBLE FOR THE DELAY, SUPPOSIVELY SHE COULD NOT BARE TO LOSE TWO DAUGHTERS IN ONE YEAR. UPON MARRIAGE TO JOHN, ABIGAIL MOVED TO BRAINTREE. SHE HAD TO TRANSITION FROM THE POSITION OF A FIRST FAMILY OF WEYMOUTH TO THE MODEST SOCIAL STANDING OF THE ADAMS. SOMEHOW ABIGAIL FOLLOWED THE SAME STEPS AS JOHN’S MOTHER (THE BOYLSTON, WAS ONE OF THE FIRST FAMILIES OF MASSACHUSETTS) WHO THOUGHT TO HAVE MARRIED BENEATH HER WHEN SHE CHOSE JOHN ADAMS.
Many PCP users are brought to emergency rooms because of PCP's bad psychological effects or because of overdoses. In a hospital they often become violent or suicidal, and are very dangerous to themselves and people around them. At a low dose, physiological effects of PCP include a slight increase in breathing rate and a more pronounced rise in blood pressure and pulse rate. Respiration becomes shallow, and flushing and profuse sweating occur. Numbness of the extremities may also occur.
Psilocybin’s chemical structure is C12 H17 N2 O4 P. It has a ring configuration by the name of indole attached to an ethyl amine substituent. Indole’s are aromatic compounds that have a benzene ring attached to a pyrrole ring containing nitrogen. Psilocybin’s chemical structure is derived from an amino acid and tryptamine called trypthophan. It also has a visible structural resemblance with serotonin, a neurotransmitter responsible for “happiness”. Psilocybin is very soluble in water, insoluble in organic compounds and slightly soluble in methanol and ethanol. This due to the ...

In 1945 Germany divided Berlin into four zones. The Soviet Union, United States, Britain, and France all had a zone. From 1945 until 1961 Germans were free to go from East to West Berlin. On August 13, 1961, groggy citizens watched as workers began digging holes and jackhammering sidewalks, making way for the barbed wire that would eventually divided the East and the West. Armed troops stood guard at the crossing points between the two sides. By the morning of August 14, Soviet troops surrounded the city and by the end of that night the freedom to move freely between the two sections of Berlin ended. But even before the wall went up East Berlin had tried to push West Berlin away by cutting off all food and supplies to them. On June 27, 1948, the Berlin Airlift occurred. The United States and Britain combined their zones and came together as o...
When World War II ended in 1945 there are a few things that people have learned but also may not remember from history. The fears of having another nuclear apocalypse, in Germany, was a occurring thought every day during the Cold War. Beginning with after World War II the time period then was called the Cold War. After that, Germany was spilt into two halves, the Soviet and non- Soviet. Then, leading to a barrier that separated Germany, splitting families and ruining lives for the people; only due to Soviet wanting more power. Right after that, the separation had caused west and East Berlin to think they would be forever apart… permanently… during the Cold War; though rights and freedom changed over time for the people. Finally, the people of Germany evolved to the separation, but politics and the world around Germany changed and moved on to take down the wall. The rights of Germans on either side reflect on the political changes in their country, Germany.
1945; World War II had ended. People all over the world celebrated, even the citizens in Berlin, Germany. Little did the Berliners know that their war was not over? Another war had started, a Cold War, from 1945 to 1989, tearing Berlin families and friends apart. A wall had been built up; they couldn’t travel where they wanted anymore and couldn’t speak their opinions. These were the rights taken away from East and West Berliners.

In conclusion Berlin Wall was an important milestone in the growth of the Cold War. It was the expansion that represented the thinking of a determined Communist system. Western Capitalism, which was more powerful, eventually defeated the system. The massive wall that did so much harm to a country was finally destroyed, and the people of Germany could now live the way they all wanted to live. They could live the life of freedom. Since the fall of the Berlin Wall East Germany has went through a lot of changes, and it still is not easy for all of the people in East Germany. But no matter how hard it is for the people of East Germany now, it is better than being alone and separated from their families, friends and rest of Europe.
Some celebrated by bashing down sections of the wall, most of the wall was destroyed in 1990. Germany was officially reunited in October 3, 1990. The crowds of people were enormous, they all rejoiced and were truly happy to see their family again. The Berlin Wall left an ugly dent on Germany’s History but that doesn’t mean that it can’t achieve greatness in the future. The people of Berlin and Germany are better now and learned from their mistakes. Over all The Berlin Wall connected to the theme Responsibilities and Rights very good since after the war governments in West Berlin and East Berlin rapidly and dramatically changed in terms of government.
Violent video games are undoubtedly a legalized drug to children and teens, numbing their thoughts and reprogramming their minds. Like a drug, it desensitizes them, and makes them more prone to violence. This idea of violent video games was not a phenomenon until the later 20th century, and evolved from racing into enemies, to free-for-all drug abuse and sexual/physical violence that most youth know and play today. These games have a detrimental impact on teens, making them eat more, become more aggressive, and wash away their morality. Although some may try to argue with reality, countering that its helps them socially, similar to the idea of teens taking drugs, violent video games reduce their overall health and need to be taken care of.

Other people may argue that violent video games do not affect people’s behavior at all. Cheryl Olson, Lawrence Kutner, and Dorothy Warner said that “Playing violent video games reduces violence in teenage boys by replacing rough housing. Playing violent video games allows teenage boys show their anger and create peace with his friends without anyone getting hurt”. This quote is significant because it shows how violent video games can have a good outcome on the youth. Also violent video game is a good anger reliever because it takes out a lot of anger out. Cheryl Olson and various contributors said that “Playing violent games provides a safe channel for aggressive and mad feelings. A 2007 study reported that 45% of boys played video games because “it helps me get my anger out” and 62% played because it “helps me relax””. However this is a bad habit to give to children which is substituting something bad to a little less bad. Dave Grossman and Gloria DE Gaetano said “Violent video games cause the person to experience happiness and pleasure when causing someone else pain”. If children get use to causing pain up to the point where they feel pleasure for causing it, how do you think they will act in their future? Certainly not in a positive way and t...
Sincerity: there will always be conflict within a relationship and you need to be able to apologise and realise when you are wrong. The sooner there is an apology the sooner the relationship can advance.
Research is the key to finding the proper information in explaining why some teenagers turn to violence to deal with their problems. Hundreds of studies have been done on violent video games and their effects of teenagers playing them. The results are very conflicting. The majority of the research that has been done on this subject is on single player games and takes place in a controlled environment. The environment that teenagers live in today is far from controlled. And over half of the video games played today are played by two or more players in a social forum. The largest link to violent video game players that has been found to date is increased aggression. And increased aggression is not violence. The definition of aggression in many of these studies is also vague. But whatever the definition is, it is not a definition of violent acts. To show that a person will punish someone more heavily after playing a violent video game does not prove a violent act will come from this person. To show that a violent video game will cause an increase in heart rate and decrease in empathy is als...
