Kindle Notes & Highlights
Archaeologists have uncovered ancient African images of mushrooms sprouting from a human body,
Freud himself was strongly attracted to mind-altering drugs such as cocaine and tobacco, his students were less so.
Hofmann nearly overdosed himself with what he thought was too small a quantity to possibly be mind-altering: a quarter milligram.
The presence and function of serotonin in the brain and in animal behavior clinched its role as the first known neurotransmitter.
In some experimental situations, LSD blocked the effects of serotonin; in others, the psychedelic drug mimicked serotonin’s effects.
LSD’s extraordinary sensory and emotional properties resulted from changing the function of brain serotonin in specific and understandable ways,
Subsequent publications cleared psychedelics from serious toxicity, including chromosome damage. However, these follow-up studies generated much less fanfare than did the original damaging reports.
This never happened with the psychedelic drugs. Instead, their study went through a highly unnatural evolution. They began as “wonder drugs,” turned into “horror drugs,” then became nothing.
Set is our own makeup, both long term and immediate. It is our past, our present, and our potential future; our preferences, ideas, habits, and feelings. Set also includes our body and brain.
There are two main chemical families of psychedelic drugs: the phenethylamines and the tryptamines.
The phenethylamines build upon the “parent compound” phenethylamine.
The best-known phenethylamine is mescaline,
Another famous phenethylamine is MDMA,
Tryptamine is a derivative of tryptophan, an amino acid present in our diet.
Serotonin is a tryptamine—5-hydroxy-tryptamine, to be exact
Another more basic aspect of pharmacology is “mechanism of action,” or how drugs affect brain activity.
These multiple docking sites for serotonin exist in high concentrations on nerve cells in brain areas regulating a host of important psychological and physical processes:
William Burroughs, author of The Naked Lunch, was one of the earliest field users of DMT.
DMT is the simplest of the tryptamine psychedelics.
Compared to other molecules, DMT is rather small. Its weight is 188 “molecular units,”
the brain actively transports DMT across the blood-brain barrier into its tissues. I know of no other psychedelic drug that the brain treats with such eagerness.
The widespread presence of MAO is why DMT effects are so short-lived.
just as likely as the theory that these worlds exist “only in our minds” is that they are, in reality, “outside” of us and freestanding.
the mysterious pineal gland. In its role as a potential “spirit gland,” or producer of endogenous DMT,
Descartes believed that the pineal gland played an essential role in the expression of the soul:
the pineal gland does not originate from brain tissue, it exists outside the blood-brain barrier
melatonin contributes to the early morning drop in body temperature.
One of the most robust is body temperature, in which there is a sharp dip at 3 A.M.
Individuals with schizophrenia received pineal gland extracts as an experimental treatment in the 1960s.
Researchers have found that the methyltransferase enzymes that form DMT are more active in schizophrenia than in normal conditions.
MAO is less efficient in schizophrenics
it may be that schizophrenics do not clear DMT quickly enough from their systems.
