Your Brain on Books

Your Brain on Books

Scientific American interviews Stanislas Dehaene, author of The Number Sense and Reading in the Brain. Dehaane talks a little about what happens in the brain when we read and how it’s almost a miracle that we can read at all. From the article:

One of my long-time interests concerns how the human brain is changed by education and culture. Learning to read seems to be one of the more important changes that we impose to our children’s brain. The impact that it has on us is tantalizing. It raises very fundamental issues of how the brain and culture interact.

As I started to do experimental research in this domain, using the different tools at my disposal (from behavior to patients, fMRI, event-related potentials, and even intracranial electrodes), I was struck that we always found the same areas involved in the reading process. I began to wonder how it was even possible that our brain could adapt to reading, given it obviously never evolved for that purpose. The search for an answer resulted in this book. And, in the end, reading forces us to propose a very different view of the relationship between culture and the brain.

Pixelated Brains and New Media

Popmatters has been running a feature called Pixalated Brains and New Media which are a series of articles that deal with the web, reading, our short attention spans, online social networking, and many other digital concerns, worries, hopes, and dreams. I started with Scratching the Surface: Your Brain on the Internet via Metafilter. Here’s a snip to the intro of the series:

There’s a great deal of concerned talk, talk, talk out there about our shortening attention span, and it seems our demise (because let’s be frank – the overall tone is that whatever is happening to us is bad for the species) is all thanks to the advent of New Media. You know, all those pixel bits of blog entries, TV news quips shouting at us between blaring 30-second commercials, three-line gossipy blips under BIG PICTURES in glossy mags, proper grammar and punctuation lost to text messaging, sound bytes bouncing along the airwaves at varying decibels …  Via these methods we nibble from an array of fast foods for thought, taking from what’s presented that which we like, eschewing the rest and flitting off, or perhaps Twittering off, to the next pretty shiny thing.

Our Brainwaves Sound Like Jazz

Music of the Brain

Ever wonder how your mind sounds like? No, I’m not talking about Kings of Leon’s Use Somebody stuck in your head, but of how would your brain activity could be converted to sound. Some really hip researchers have done just that converting brain waves using electroencephalograms to sound pitches, i.e., notes. Here’s the “why” of this research:

But the question is: why convert brain waves into sound? Well…because it’s cool. No really, there’s another reason. Humans actually hear pretty well in a pretty wide range. More importantly, we can hear very small changes in pitch and rhythm. And sound patterns (because of our extensive use of language) may be easier for us to distinguish compared to really complicated visual patterns. So the idea is to turn brain activity into sound, and see if you can come up with anything. Perhaps, for example, people could compare a normal brain with an epileptic one, and hear differences. Of course, differences during a seizure would be pretty obvious, but it’s possible, if the technique got refined enough, that people could be trained to “hear” differences resulting from things like schizophrenia or Alzheimer’s, which could aid in diagnosis, and thus in treatment.

Here’s a brain on R.E.M. during sleep.

Intense and Deliberate Practice

Genius: The Modern View

NYT Op-Ed by David Brooks where he argues that what makes a person a “genius” is their intense and deliberate practice and not their genetic makeup. Like Gladwell, he mentions the 10,000 hour rule.

The latest research suggests a more prosaic, democratic, even puritanical view of the world. The key factor separating geniuses from the merely accomplished is not a divine spark. It’s not I.Q., a generally bad predictor of success, even in realms like chess. Instead, it’s deliberate practice. Top performers spend more hours (many more hours) rigorously practicing their craft.

Perhaps it still has a lot to do with genes, but the intelligence and creativity acquired doesn’t happen out of “thin air”. It’s individuals that are “hardwired” to do whatever it takes to learn everything they can about x subject.

What We Can Learn From Babies Brains

Inside the Baby Mind

The Boston Globe article takes a look at the brain of infants. When compared to adults, new studies have shown that an infants brain is more sophisticated than it was believed. From the article:

Scientists have begun to dramatically revise their concept of a baby’s mind. By using new research techniques and tools, they’ve revealed that the baby brain is abuzz with activity, capable of learning astonishing amounts of information in a relatively short time. Unlike the adult mind, which restricts itself to a narrow slice of reality, babies can take in a much wider spectrum of sensation – they are, in an important sense, more aware of the world than we are.

Hacking Your Brain with Pills

Brain Gain - The Underground World of “Neuroenhancing” Drugs

In depth New Yorker article about people using “neuroenhancers” such as Provigil, Aderall, and others to have a competitive edge. Ivy league college students around America have been taking so called brain steriods to “cheat” (or handle better) their tough academic schedules. It deals with the ethical questions it raises, the known or mostly unknown possible side effects, and really… people that are possibly addicted to drugs. From the article:

Unlike many hypothetical scenarios that bioethicists worry about—human clones, “designer babies”—cognitive enhancement is already in full swing. Even if today’s smart drugs aren’t as powerful as such drugs may someday be, there are plenty of questions that need to be asked about them. How much do they actually help? Are they potentially harmful or addictive? Then, there’s the question of what we mean by “smarter.” Could enhancing one kind of thinking exact a toll on others? All these questions need proper scientific answers, but for now much of the discussion is taking place furtively, among the increasing number of Americans who are performing daily experiments on their own brains.

We Are All Dim Bulbs

Computers Vs Brains

The brain as a computer analogy is the best thing we have, but we’re still very far away from truly understanding it’s complex engineering. One fascinating bit the NYT article mentions is the power that an artificial brain would need to consume for it to work.

By 2025, the memory of an artificial brain would use nearly a gigawatt of power, the amount currently consumed by all of Washington, D.C.

In contrast our brain uses much less power, but has the capacity to store an estimated 3 petabytes, which is approximately the archived contents of the internet.

Compare this with your brain, which uses about 12 watts, an amount that supports not only memory but all your thought processes. This is less than the energy consumed by a typical refrigerator light, and half the typical needs of a laptop computer. Cutting power consumption by half while increasing computing power many times over is a pretty challenging design standard. As smart as we are, in this sense we are all dim bulbs.

You Just Can’t Beat Pen and Paper

Paper and Pencil, Not Computer, Boost Creativity

I think we have always known that the act of writing on paper makes our brains better. There’s something about the simplicity, the blank page, and the use of a pen. It makes our thoughts clearer somehow. Not just writers now this. Everyone “knows” that typing on a word processing program feels mentally miles apart from writing in a notebook. But we haven’t been able to explain this intuitive knowledge in a scientific manner. According to research done by Dutch psychologist Van Nimwegen, people that used pen and paper to solve problems were more creative and faster than the ones that used a computer. From the article:

Van Nimwegen says much software turns us into passive beings, subjected to the whims of computers, randomly clicking on icons and menu options. In the long run, this hinders our creativity and memory, he says. 

So start writing in that notebook before it’s too late.

Brave New World of Digital Intimacy

Writer Clive Thompson writes in NyTimes a sociology and psychology CliffsNotes on theories like “ambient awareness”, the “Dumbar number”, and “parasocial relationships” to try to understand the whole social networking “microblogging” phenomenon and focuses most of the time on web trends like Facebook’s Newsfeed and Twitter. I don’t agree completely with the idea it’s trying to sell that ephemeral relationships and exchanges mean more than they actually do, but I do agree that not every relationship has to be intimate to be meaningful or to have some value.

Daydream Achiever

We have discouraged daydreaming because we have switched to valuing more the idea of focus. “Letting your mind wander is not productive” you read and hear. It is true that when you’re focused, your chances of resolving problems increases, but daydreaming leads to more problem-solving breakthroughs that people may be are aware of. It warns though, that not every daydreamer is a creative genius:

“The point is that it’s not enough to just daydream,” Schooler says. “Letting your mind drift off is the easy part. The hard part is maintaining enough awareness so that even when you start to daydream you can interrupt yourself and notice a creative insight.”

Structured Procrastination

I’ve always felt bad for being a procrastinator, but I’ve slowly learned not to be too tough on myself. David Allen, the GTD founder, once said in a interview, “procrastination is not about not doing, is about not doing and feeling crappy about it”. It isn’t that procrastinators don’t do anything, (if that’s happening, you’re probably clinically depressed) because we do many things. The problem is that we suck at deadlines and get distracted by the seemingly unimportant. This article helps you structure it in a very creative way.

Want to Remember Everything You’ll Ever Learned? Surrender to this Algorithm

This is an article that Wired ran in their “Get Smarter” May issue. It’s about Piotr Wozniak and his learning software called Supermemo which is based on the spaced repetition learning tecnique. Probably one the most powerful “mind hacks”, but something that could turn into an obsession.

Dangerous Ideas: Getting Started is Overrated

If you have read some of my posts, you’ll notice that I like to challenge conventional wisdoms. This is an article that challenges the advice of “just get started” and suggest that the initial alternative of studying your options and thinking before submitting to action might be a better idea.
