An Ode to the Brain: TED + Carl Sagan, Autotuned

By:

Between our deep love for TED, our fascination with music and the brain, and our soft spot for remix culture, it’s hard not to fall for An Ode to the Brain by John Boswell of Symphony of Science fame — an ingenious autotune remix of footage from various TED talks, Discovery Channel programming, Carl Sagan documentaries and other fine purveyors of neuroscience insight.

For our very own remix tribute to TED, do revisit our TEDify side project.

Thanks, Chris

40K Books: 99-Cent Essays by Million-Dollar Authors

By:

Trying out the Italian cyberpunk job, or how to buy brilliance for under a dollar.

Over the last few months we’ve taken a few trips to the frontier of electronic publishing to see how various digital developers are building out the landscape. One such new settler is 40K Books, so named because its 99-cent essays and novellas take 40 minutes to just over an hour to read. The Milan, Italy-based startup has put out a series of original works in English, French, Italian, Portuguese, and Spanish, both from new writers and established authors and thinkers like Bruce Sterling and Paul Di Filippo. Its non-fiction selections focus on the consequences of and ways in which our “culture is going digital,” while the short fiction skews toward futurist, sci-fi topics. We were sold by 40K’s bold graphic style but stuck around for the imaginative content of the work itself. Here are three favorites from the first run of releases.

FROM WORDS TO BRAIN

MIT graduate student and neuroscientist Livia Blackburne penned the fantastic essay From Words to Brain (Can neuroscience teach you to be a better writer?), which uses the children’s classic “Little Red Riding Hood” to investigate the complex neural connections that take place while we read. Like the TEDBooks series, Blackburne’s piece contains big ideas in a compact, engaging, and accessible package.

For most of human history, written language didn’t even exist. Reading as a cultural invention has only been around for a few thousand years, a snap of a finger in evolutionary terms. We have not, and will not, within any of our lifetimes, evolve a genetic program for reading. Yet our brains are so adept at this skill that it become as reflexive as seeing itself.”

SELLING STORIES SUCCESSFULLY

British marketing professor Stephen Brown authored the highly entertaining piece Selling Stories Successfully, at once a manifesto for “self-promotion and shameless authorpreneurship” and an exploration of what makes for good contemporary fiction. We took assiduous notes – or rather annotated our digital text – while reading this guide for writers who want to see their work get onto shelves and screens.

You have to persuade people to buy it, both literally and metaphorically. You’ve woken up to the fact that storytelling and storyselling are two completely different things. As J.G. Ballard once ruefully observed: ‘any fool can write a novel but it takes real genius to sell it.'”

BLACK SWAN

Master of cyberlit Bruce Sterling spins this enthralling tale about an Italian technology blogger, his unexpected hacker ally, and their discovery – something that threatens to revise history as we know it. We started reading Black Swan and couldn’t put down our Kindle until the last word.

I could explain now, in grueling detail, exactly what memristors are, and how different they are from any standard electronic component. Suffice to understand that, in electronic engineering, memristors did not exist. Not at all. They were technically possible – we’d known that for thirty years, since the 1980s – but nobody had ever manufactured one. A chip with memristors was like a racetrack where the jockeys rode unicorns.”

After these action- and insight-packed reads, we’re very much looking forward to seeing what stakes 40K Books pitches next.

Vision Revolution: Why We See The Way We Do

By:

Why do we see the way we do? Since the dawn of humanity’s fascination with the brain, scientists have tried to answer this question. But, as it turns out, much of what they thought to be true was wrong. In The Vision Revolution: How the Latest Research Overturns Everything We Thought We Knew About Human Vision, neuroscientist Mark Changizi — whose work has graced the pages of merchants of culture like TIME, Newsweek, New Scientist and The New York Times — offers groundbreaking insights into the science of how and why we see as we do through thoughtfully curated highlights from breakthrough research, complete with illuminating illustrations and diagrams that visualize his conclusions.

To understand how culture interacts with vision, one must understand not just the eye’s design, but the actual mechanisms we have evolved, for culture can tap into both the designed responses of our brains and the unintended responses.” ~ Mark Changizi

Changizi focuses on four fundamental “why” questions — why do we see in color, why do our eyes face forward, why do we see illusions, and why does reading come so naturally to us — the answers to which will surprise you.

For instance, scientists used to believe that color vision evolved to help our ancestors spot ripe fruit. It turns out, however, that it actually evolved to give us greater insight into the mental, emotional and physical states of other people: People who can see color changes in skin have a competitive edge over those who can’t because they can detect the reddening of rashes and know when others are blushing with embarrassment or purple-faced with exertion. (It’s unsurprising, then, that primates who have color vision are the ones who have no fur or hair on their faces and other instrumental body parts.) Even more interestingly, Changizi reveals that the cones in our eyes are exquisitely designed to see these skin color changes.

Perhaps most fascinatingly, Changizi illuminates the neuropsychology of illusions, which are the result of our brains’ evolutionary need to micro-predict the motion of objects. (You know a baseball is about to hit you in the face before it does, because you can project its trajectory, which allows you to react accordingly.) Simply put, illusions happen when the brain is tricked into believing a static two-dimensional picture has a moving element, projecting that element into the future and seeing not what is actually on the page but what our brain thinks will be there a fraction of a second later.

If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited — which takes about a tenth of a second for the brain to do — time would have marched on, and the perception would be of the recent past.” ~ Mark Changizi

Deeply fascinating yet absorbingly readable, The Vision Revolution comes as a necessary foundation for better understanding one of our most fundamental tools for navigating the world and, in the process, better understanding ourselves.

7 Essential Books on Music, Emotion, and the Brain

By:

What Freud has to do with auditory cheesecake, European opera and world peace.

Last year, Horizon’s fascinating documentary on how music works was one of our most-liked pickings of 2010. But perhaps even more fascinating than the subject of how music works is the question of why it makes us feel the way it does. Today, we try to answer it with seven essential books that bridge music, emotion and cognition, peeling away at that tender intersection of where your brain ends and your soul begins.

MUSICOPHILIA

We love the work of neuroscientist and prolific author Oliver Sacks, whose latest book, The Mind’s Eye, was one of our favorite brain books last year. But some of his most compelling work has to do with the neuropscyhology of how music can transform our cognition, our behavior, and our very selves. In Musicophilia: Tales of Music and the Brain, Revised and Expanded Edition, Sacks explores the most extreme of these transformations and how simple harmonies can profoundly change lives. From clinical studies to examples from pop culture — did you know that Ray Charles believed he was “born with the music inside [him]”? — Sacks delivers a fascinating yet remarkably readable tale that tells the story, our story, of humanity as a truly “musical species.”

THIS IS YOUR BRAIN ON MUSIC

Why music makes us feel the way it does is on par with questions about the nature of divinity or the origin of love. In This Is Your Brain on Music: The Science of a Human Obsession, Daniel Levitin sets out to answer it — an ambitious task he tackles through a range of lenses, from a digestible explanation of key technical constructs like scale, tone and timbre to compelling cross-disciplinary reflections spanning neurobiology, philosophy, cognitive psychology, memory theory, behavioral science, Gestalt psychology and more. He illuminates diverse subjects like what accounts for the diversity of musical tastes and what makes a music expert, framing music processing as a fundamental cognitive function embedded in human nature. Most impressively, however, Levitin manages to do this while preserving the without subtracting from the intuitive, intangible magic of powerful music, dissecting its elements with the rigor of a researcher while preserving its magnetism with the tenderness of a music lover.

Never ones to pass up a good ol’ fashioned erudite throw-down, we can’t resist pointing out that the book’s final chapter, The Music Instinct, may be the juciest: It’s a direct response to Harvard psycholinguist Steven Pinker, who in a 1997 talk famously called music “auditory cheesecake” and dismissed it as evolutionarily useless, displacing demands from areas of the brain that should be handling more “important” functions like language. (Obviously, as much as we love Pinker, we think he’s dead wrong.) Levitin debunks this contention with a mighty arsenal of research across anthropology, history and cognitive science, alongside chuckle-worthy pop culture examples. (It’s safe to assume that it was musical talent, rather than any other, erm, evolutionary advantage, that helped Mick Jagger propagate his genes.)

MUSIC, LANGUAGE, AND THE BRAIN

As if to drive a stake through the heart of Levitin and Pinker’s debate, Music, Language, and the Brain by Aniruddh Patel — both a musician himself and one of the greatest living neuroscientists — dissects the unique neuropsychological relationship between two of the most unique hallmarks of our species. Rigorously researched and absorbingly narrated, the book traces the origins of humanity’s understanding of this correlation, dating as far back as the philosophical debates of Ancient Greece, and challenges the scientific community’s longstanding assumption that music and language evolved independently of one another. It’s the kind of read that will leave you at once astounded by how much you’ve learned about its subject and keenly aware of how little you — how little we, as a culture — know about it.

Patel also offers this beautiful definition of what music is:

Sound organized in time, intended for, or perceived as, aesthetic experience.

It’s worth noting that Music, Language, and the Brain makes a fine addition to our list of 5 must-read books about language.

LISTEN TO THIS

In 2008, New Yorker music critic Alex Ross published The Rest Is Noise: Listening to the Twentieth Century — a remarkable historical and social context for contemporary music, which went on to become one of the most influential music history books ever written. Last fall, Ross released his highly anticipated sequel: Listen to This — an outstanding effort to explain and understand the world through its musical proclivities, from European opera to Chinese classical music to Bjork. Though the book, an anthology of the author’s most acclaimed essays with a deeper focus on classical music, is further removed from neuroscience than the rest on this list, Ross’s astute observations on the emotional and social experience of music make it an indispensable addition nonetheless.

MUSIC, THE BRAIN AND ECSTASY

If the human voice is the greatest instrument, as the widespread music teacher preaching goes, then the brain is the greatest composer. Every time we perform, compose or merely listen to music, the brain plays high-level Tetris with a range of devices, harmonies and patterns, creating emotional meaning out of the elements of sound and often extracting intense pleasure. In Music, The Brain, And Ecstasy: How Music Captures Our Imagination, composer Robert Jourdain examines music’s unusual emotive power through little-known facts and physiological phenomena and historical anecdotes. Perhaps most fascinatingly, he pins down the origin of pleasure in music as a consequence of a series of tonal deviations that create a conflict in the brain, resolved with a return to the tonal center, which gives us a sensation of bliss. This sequence of conflict and resolution, he explains, can come from the four key elements of music: rhythm, melody. phrase, and harmony. “Ecstasy” is the result of a resolution that comes once a conflict has reached the limit of the listener’s comprehension ability in tonal space-time.

THE TAO OF MUSIC

Traditional self-help books are the pesky cold sore swapped between the lips of legitimate literature and serious psychology. And then there are the books that actually help the self in smart, non-pedantic ways involving no worksheets or mirror nodding. That’s exactly what John Ortiz does in The Tao of Music: Sound Psychology, blending the extraordinary power of music with the principles of Taoist philosophy to deliver an unusual yet captivating proposition: You can enlist your music library in improving your performance and state of mind across everyday challenges like keeping anger at bay, breaking the spell of procrastination, learning to be fully present with romantic relationships, and mastering the art of true relaxation. Through cognitive-behavioral exercises, meditative techniques and melodic visualizations, Ortiz offers a powerful music-driven toolkit for navigating life’s obstacles, and even curates specific “musical menus” of songs and melodies that target specific emotional states and psychological dispositions.

MUSIC AND THE MIND

Nearly two decades after its original publication, Anthony Storr’s Music and the Mind remains an essential and timeless prism for looking at one of humanity’s greatest treasures. From the biological basis of cognition to a thoughtful analysis of the views held by history’s greatest philosophers to the evolution of the Western tonal system, Storr addresses some of the most fundamental questions about music, like why a minor scale always sounds sad and a major scale happy, and offers an evidence-backed yet comfortingly human grand theory for the very purpose of music: Peace, resolution and serenity of spirit.
