  • The biosinthetic path that allow Psilocybin to be produced by mushrooms is as follow:
  • The several analogyes with triptophan aminoacid, with whom psilocybin has common origines are probably at the base of psilocybin ability to induced psychedelich alteration on humans.
  • Amino acids, including tryptophan, act as building blocks in protein biosynthesis. In addition, tryptophan functions as a biochemical precursor for many compounds like serotonin Serotonin (a neurotransmitter), synthesized via tryptophan hydroxylase. Serotonin, in turn, can be converted to melatonin (a neurohormone), via N-acetyltransferase and 5-hydroxyindole-O-methyltransferase activities

  • it's been noticed that psilocyn can indirectly raise dopamine concentration withing the basal ganglia.
  • Almost 50% of oral psilocybin is absorbed by stomach and gut; from here is lead to liver, where it's converted in psilocin, pharmacologically active form, that can furtherly be glucoronated and escreted with urine or converted in other psilocinics metabolites.
  • In rats, the median lethal dose (LD50) when administered orally is 280 milligrams per kilogram (mg/kg), approximately one and a half times that of caffeine. When administered intravenously in rabbits, psilocybin's LD50 is approximately 12.5 mg/kg
  • traces of the compund can be detected in unine even after 7 days.
  • Clinical studies show that psilocin concentrations in the plasma of adults average about 8 µg/liter within 2 hours after ingestion of a single 15 mg oral psilocybin dose; psychological effects occur with a blood plasma concentration of 4–6 µg/liter. Psilocybin is about 100 times less potent than LSD on a weight per weight basis, and the physiological effects last about half as long.
  • Within 24 hours from administration 65% of the alucinogen is escreted by urine, while another 15-20% is excreted by bile and feces.
  • Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of psilocybin. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and β-carboline. Tobacco smokers can also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases levels of MAO in the brain and peripheral organs.
  • This could lead to a lower usage o f glucose, but the same study admitted an increase glucose usage by the whole brain cell, meaning a differente use of this sugar while the drug is having effects.
  • use of MRI (functional magnetic resounance) showed that the decresed blood flow associate with decreasing in neural activity. A simple explanation for this unexpected situation could be the serotoning agonist action of psilocybin, action that seems to be focused more on 5-HT receptors than on 5-HT2A.
  • psilocibyn is able to act as a 5-HT agonist binding directly its receptors.
  • augmented glucose consumption in several brain regions; this lead to the conclusion that psilocybin is some way able to modify the physiological glucosal metabolic rate of our body
  • The strong inibition of the PCC is now thought to be most significant action of psilocybin on neural disaccoppiation

      Lower brain glucose metabolism is linked with increased capacity for working memory.
  • Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD50 value.
  • psilocybin can cause anxiety and increased heart rate and BP which is very counter- productive for someone on metoprolol and micardis.
  • propose the possibility to use psilocybin as a palliative therapy for terminal illness like cancer but also as a real antidepressive active principle available for the family of the patient. The rational is foundable in the fact that we usually administer SSRI as antidepressive agents, so psilocibyn sholud be useful in this purpose for its selective agonist action on 5-HT2A receptors

  • Of greatest importance, however, is the status of our thinking, understanding how we think and the effect new technologies have on our cognitive processes. This debate extends beyond the neuroscience to questions relating to what is worth knowing and what mental functions are worth preserving at their present level of development
  • As a senior high school teacher, one of my greatest bugbears is the reluctance of students to reflect on the information they have collected and plan their essays. Rather, some expect to Google their entire essay, often skipping from one hyperlink to the next until they find something that appears to be relevant, then pasting it into their essay, frequently oblivious to academic honesty and coherence of argument. The ability to discern reliability of sources is also severely lacking

      No- it should begin with teachers establishing and negotiating meaningful, interesting, and powerful learning opportunities with access to all available tools. The computer as a learning tool is meant to extend physical human capabilities, not weaken them. It is the low-level, rote tasks that we require that weaken them. It's time to recognize this and wake up. Blaming the technology does little more than preserve the status quo.

    I have to say, I watched this when it aired, and it was infuriating to me. Like most educators, I get really excited when there is talk of tech in the classroom. This video does not have a counter-argument. What I got from it was, "Hey, look at all of this cool stuff these schools are doing." I am ready for schools to take this approach. I am ready to go for it. However, I would like to see a documentary on the numerous hurdles to having education like this in the other 99.9% of public schools. Some of these schools get to hand-pick students, or are on a lottery system. How about the cost? Or the professional development? Or the inequity in public school funding? With a couple exceptions, all I could see were dollar signs when I watched this. Money that is not there, and won't be for some time. If you want to feel behind the times, inadequate about your teaching/pedagogy, or flat out jealous, this is the video for you.

  • When it comes to showing results, he said, “We better put up or shut up.”
  • Critics counter that, absent clear proof, schools are being motivated by a blind faith in technology and an overemphasis on digital skills — like using PowerPoint and multimedia tools — at the expense of math, reading and writing fundamentals. They say the technology advocates have it backward when they press to upgrade first and ask questions later.

  • Schools are safe havens where children should be able to learn and grow in a supportive atmosphere. At home, parents have the ability to monitor their children’s intake of consumer products by limiting television and internet usage, and helping them engage critically with the content they see. But if we allow advertising in any form in our schools, we run directly counter to the message educational institutions are trying to promote: that these are places of learning, not selling.

  • One of the most profound changes that occurs when modern schooling is introduced into traditional societies around the world is a radical shift in the locus of power and control over learning from children, families, and communities to ever more centralized systems of authority.
  • Once learning is institutionalized under a central authority, both freedom for the individual and respect for the local are radically curtailed.  The child in a classroom generally finds herself in a situation where she may not move, speak, laugh, sing, eat, drink, read, think her own thoughts, or even  use the toilet without explicit permission from an authority figure.
  • In what should be considered a chilling development, there are murmurings of the idea of creating global standards for education – in other words, the creation of a single centralized authority dictating what every child on the planet must learn.
  • ...26 more annotations...
  • In “developed” societies, we are so accustomed to centralized control over learning that it has become functionally invisible to us, and most people accept it as natural, inevitable, and consistent with the principles of freedom and democracy.   We assume that this central authority, because it is associated with something that seems like an unequivocal good – “education” – must itself be fundamentally good, a sort of benevolent dictatorship of the intellect. 
  • We endorse strict legal codes which render this process compulsory, and in a truly Orwellian twist, many of us now view it as a fundamental human right to be legally compelled to learn what a higher authority tells us to learn.
  • And yet the idea of centrally-controlled education is as problematic as the idea of centrally-controlled media – and for exactly the same reasons.
  • The First Amendment of the U.S. Constitution was designed to protect all forms of communication, information-sharing, knowledge, opinion and belief – what the Supreme Court has termed “the sphere of intellect and spirit” – from government control.
  • by the mid-19th century, with Indians still to conquer and waves of immigrants to assimilate, the temptation to find a way to manage the minds of an increasingly diverse and independent-minded population became too great to resist, and the idea of the Common School was born.
  • We would keep our freedom of speech and press, but first we would all be well-schooled by those in power.
  • A deeply democratic idea — the free and equal education of every child — was wedded to a deeply anti-democratic idea — that this education would be controlled from the top down by state-appointed educrats.
  • The fundamental point of the Occupy Wall Street movement is that the apparatus of democratic government has been completely bought and paid for by a tiny number of grotesquely wealthy individuals, corporations, and lobbying groups.  Our votes no longer matter.  Our wishes no longer count.  Our power as citizens has been sold to the highest bidder.
  • Our kids are so drowned in disconnected information that it becomes quite random what they do and don’t remember, and they’re so overburdened with endless homework and tests that they have little time or energy to pay attention to what’s happening in the world around them.
  • If in ten years we can create Wikipedia out of thin air, what could we create if we trusted our children, our teachers, our parents, our neighbors, to generate community learning webs that are open, alive, and responsive to individual needs and aspirations?  What could we create if instead of trying to “scale up” every innovation into a monolithic bureaucracy we “scaled down” to allow local and individual control, freedom, experimentation, and diversity?
  • The most academically “gifted” students excel at obedience, instinctively shaping their thinking to the prescribed curriculum and unconsciously framing out of their awareness ideas that won’t earn the praise of their superiors.  Those who resist sitting still for this process are marginalized, labeled as less intelligent or even as mildly brain-damaged, and, increasingly, drugged into compliance.
  • the very root, the very essence, of any theory of democratic liberty is a basic trust in the fundamental intelligence of the ordinary person.   Democracy rests on the premise that the ordinary person — the waitress, the carpenter, the shopkeeper — is competent to make her own judgments about matters of domestic policy, international affairs, taxes, justice, peace, and war, and that the government must abide by the decisions of ordinary people, not vice versa.  Of course that’s not the way our system really works, and never has been.   But most of us recall at some deep level of our beings that any vision of a just world relies on this fundamental respect for the common sense of the ordinary human being.
  • This is what we spend our childhood in school unlearning. 
  • If before we reach the age of majority we must submit our brains for twelve years of evaluation and control by government experts, are we then truly free to exercise our vote according to the dictates of our own common sense and conscience?  Do we even know what our own common sense is anymore?
  • We live in a country where a serious candidate for the Presidency is unaware that China has nuclear weapons, where half the population does not understand that Saddam Hussein had nothing to do with 9/11, where nobody pays attention as Congress dismantles the securities regulations that limit the power of the banks, where 45% of American high school students graduate without knowing that the First Amendment of the Constitution guarantees freedom of the press.   At what point do we begin to ask ourselves if we are trying to control quality in the wrong way?
  • Human beings, collaborating with one another in voluntary relationships, communicating and checking and counter-checking and elaborating and expanding on one another’s knowledge and intelligence, have created a collective public resource more vast and more alive than anything that has ever existed on the planet.
  • But this is not a paeon to technology; this is about what human intelligence is capable of when people are free to interact in open, horizontal, non-hierarchical networks of communication and collaboration.
  • Positive social change has occurred not through top-down, hierarchically controlled organizations, but through what the Berkana Institute calls “emergence,” where people begin networking and forming voluntary communities of practice. When the goal is to maximize the functioning of human intelligence, you need to activate the unique skills, talents, and knowledge bases of diverse individuals, not put everybody through a uniform mill to produce uniform results. 
  • You need a non-punitive structure that encourages collaboration rather than competition, risk-taking rather than mistake-avoidance, and innovation rather than repetition of known quantities.
  • if we really want to return power to the 99% in a lasting, stable, sustainable way, we need to begin the work of creating open, egalitarian, horizontal networks of learning in our communities.
  • They are taught to focus on competing with each other and gaming the system rather than on gaining a deep understanding of the way power flows through their world.
  • And what could we create, what ecological problems could we solve, what despair might we alleviate, if instead of imposing our rigid curriculum and the destructive economy it serves on the entire world, we embraced as part of our vast collective intelligence the wisdom and knowledge of the world’s thousands of sustainable indigenous cultures?
  • They knew this about their situation: nobody was on their side.  Certainly not the moneyed classes and the economic system, and not the government, either.  So if they were going to change anything, it had to come out of themselves.
  • As our climate heats up, as mountaintops are removed from Orissa to West Virginia, as the oceans fill with plastic and soils become too contaminated to grow food, as the economy crumbles and children go hungry and the 0.001% grows so concentrated, so powerful, so wealthy that democracy becomes impossible, it’s time to ask ourselves; who’s educating us?  To what end?  The Adivasis are occupying their forests and mountains as our children are occupying our cities and parks.  But they understand that the first thing they must take back is their common sense. 
  • They must occupy their brains.
  • Isn’t it time for us to do the same?
  • Andrew McCluskey on 11 Feb 13
     
    Carol Black, creator of the documentary, "Schooling the World" discusses the conflicting ideas of centralized control of education and standardization against the so-called freedom to think independently--"what the Supreme Court has termed 'the sphere of intellect and spirit" (Black, 2012). Root questions: "who's educating us? to what end?" (Black, 2012).
