Available in PDF, EPUB and Kindle. Book excerpt: We're all familiar with the idea that plant-derived chemicals can have an impact on the functioning of the human brain. Most of us reach for a cup of coffee or tea in the morning, many of us occasionally eat some chocolate, some smoke a cigarette or take an herbal supplement, and some people use illicit drugs. We know a great deal about the mechanisms by which the psychoactive components of these various products have their effects on human brain function, but the question of why they have these effects has been almost totally ignored. This book sets out to describe not only how, in terms of pharmacology or psychopharmacology, but more importantly why plant- and fungus-derived chemicals have their effects on the human brain. The answer to this last question resides, in part, with the terrestrial world's two dominant life forms, the plants and the insects, and the many ecological roles the 'secondary metabolite' plant chemicals are trying to play; for instance, defending the plant against insect herbivores whilst attracting insect pollinators. The answer also resides in the intersecting genetic heritage of mammals, plants, and insects and the surprising biological similarities between the three taxa. In particular it revolves around the close correspondence between the brains of insects and humans, and the intercellular signaling pathways shared by plants and humans. Plants and the Human Brain describes and discusses both how and why phytochemicals affect brain function with respect to the three main groups of secondary metabolites: the alkaloids, which provide us with caffeine, a host of poisons, a handful of hallucinogens, and most drugs of abuse (e.g. morphine, cocaine, DMT, LSD, and nicotine); the phenolics, including polyphenols, which constitute a significant and beneficial part of our natural diet; and the terpenes, a group of multifunctional compounds which provide us with the active components of cannabis and a multitude of herbal extracts such as ginseng, ginkgo and valerian.

Available in PDF, EPUB and Kindle. Book excerpt: THE INSPIRATION FOR THE MAJOR NEW NETFLIX SERIES, HOW TO CHANGE YOUR MIND 'It's a trip - engrossing, eye-opening, mind altering' New Statesman 'Fascinating. Pollan is the perfect guide ... curious, careful, open minded' The Guardian Of all the many things humans rely on plants for, surely the most curious is our use of them to change consciousness: to stimulate, calm, or completely alter the qualities of our mental experience. In This Is Your Mind On Plants, Michael Pollan explores three very different drugs - opium, caffeine and mescaline - and throws the fundamental strangeness of our thinking about them into sharp relief. Exploring and participating in the cultures that have grown up around these drugs, while consuming (or in the case of caffeine, trying not to consume) them, Pollan reckons with the powerful human attraction to psychoactive plants, and the equally powerful taboos. In a unique blend of history, science, memoir and reportage, Pollan shines a fresh light on a subject that is all too often treated reductively. In doing so, he proves that there is much more to say about these plants than simply debating their regulation, for when we take them into our bodies and let them change our minds, we are engaging with nature in one of the most profound ways we can. This ground-breaking and singular book holds up a mirror to our fundamental human needs and aspirations, the operations of our minds and our entanglement with the natural world.

Available in PDF, EPUB and Kindle. Book excerpt: A research scientist’s fascinating study of plant communication reveals how we “have been misunderstanding plants, and ourselves, for all of history” (The Paris Review). “A compelling story of discovery . . . [that] will change the way you see the world”—for fans of The Hidden Life of Trees (Robin Wall Kimmerer, author of Braiding Sweetgrass) In this “phytobiography”—a collection of stories written in partnership with a plant—research scientist Monica Gagliano shares genuine first-hand accounts from her research into plant communication and cognition. By transcending the view of plants as the objects of scientific materialism, Gagliano encourages us to rethink plants as people—beings with subjectivity, consciousness, and volition, and hence having the capacity for their own perspectives and voices. The book draws on up-close-and-personal encounters with the plants themselves, as well as plant shamans, indigenous elders, and mystics from around the world and integrates these experiences with an incredible research journey and the groundbreaking scientific discoveries that emerged from it. Gagliano has published numerous peer-reviewed scientific papers on how plants have a Pavlov-like response to stimuli and can learn, remember, and communicate to neighboring plants. She has pioneered the brand-new research field of plant bioacoustics, for the first time experimentally demonstrating that plants emit their own 'voices' and, moreover, detect and respond to the sounds of their environments. By demonstrating experimentally that learning is not the exclusive province of animals, Gagliano has re-ignited the discourse on plant subjectivity and ethical and legal standing. This is the story of how she made those discoveries and how the plants helped her along the way.

Download or read book A History of the Human Brain written by Bret Stetka and published by Timber Press. This book was released on 2021-03-16 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A History of the Human Brain is a unique, enlightening, and provocative account of the most significant question we can ask about ourselves.” —Richard Wrangham, author of The Goodness Paradox Just 125,000 years ago, humanity was on a path to extinction, until a dramatic shift occurred. We used our mental abilities to navigate new terrain and changing climates. We hunted, foraged, tracked tides, shucked oysters—anything we could do to survive. Before long, our species had pulled itself back from the brink and was on more stable ground. What saved us? The human brain—and its evolutionary journey is unlike any other. In A History of the Human Brain, Bret Stetka takes us on this far-reaching journey, explaining exactly how our most mysterious organ developed. From the brain’s improbable, watery beginnings to the marvel that sits in the head of Home sapiens today, Stetka covers an astonishing progression, even tackling future brainy frontiers such as epigenetics and CRISPR. Clearly and expertly told, this intriguing account is the story of who we are. By examining the history of the brain, we can begin to piece together what it truly means to be human.
