In his TED talk, Juan Enriquez ponders the economic meltdown. He also talks about wolves who dress like sheep and talk about entitlement. And he explains how the dollar in your pocket today may be worth a trillion 2010 dollars.

But more than that, Juan Enriquez offers a glimpse of the Big Reboot that is surely coming, and, I’ve gotta tell ya…it’s amazing and a little scary at the same time. I had no idea common people were already walking around with replacement tracheas and bladders and ears grown to order from their own cells.

I feel like we’re topping the peak on the roller coaster, right before the big rush; it’s going to be a very fun and thrilling ride — as long as the car doesn’t detach from the track and we aren’t flung into space and dashed on the amusement park asphalt. But nevermind the backseat pessimist…this wave is coming, in fact it’s already here, and we can choose to enjoy surfing it and hope the sharks aren’t biting, or resist and catch a choking throatful of ocean.

One of the big questions Enriquez alludes to: if you lose an eye, and doctors can replace it with an eye that can see many times better, how long before people start gouging out the good eyes they were born with and tossing them on the trash heap?

Binaural beats are auditory brainstem responses that happen when opposite ears (perhaps yours!) hear sounds of slightly different frequency.

Just as your brain puts together two 2-dimensional signals from your eyes, then processes them to get a 3D stereo image, your brain also processes two separate auditory signals (one from each ear) and combines them into a super duper spatial auditory experience.

But a funny thing happens when your brain combines two steady but slightly different signals: it creates a pulsing beat equivalent to the difference of their frequencies. The best part, at least for curious surfers hunting yet another strange but safe way to alter their state of consciousness, is that brain waves gradually follow and eventually synchronize themselves with the frequency of the pulsing beat.

In short, if you want your brain waves operating at 5 Hz (a wave frequency typically associated with deep meditation) you put a 400 Hz signal in your left ear, and a 405 signal in your right ear, then sit back and let your brain assimilate and follow the binaural beat.

Brain Waves and States of Consciousness

Most states of consciousness have corresponding brain wave frequencies.

When your brain waves are in the beta range (15-40 Hz), you are in an alert, actively working state. For example, you’re on a TV game show answering a question that may net you $100,000 after taxes. Or, you’re breaking huddle on the 50 yard line, four points down with three seconds on the clock. Or, you’re giving a friend directions to your barbeque party over the phone. There are high and low levels of Beta, but in all of them, your brain is actively engaged.

When your brain is operating in the alpha range (9-14 Hz), you’re relaxed and reflective. Taking a quiet walk in the garden? Alpha. Just came home from work, opened a beer, hit the couch? Alpha.

The theta range (5-8 Hz) shows up during very deep relaxation and meditation. During theta, you’re on autopilot, and ideas seem to flow into your brain from nowhere. Even if you never assume a lotus position, you’re probably in a theta state more often than you’d think. How about the last time you arrived at work and didn’t remember the drive? That was theta. And remember when a great idea came to you while you were taking a shower or brushing your teeth? Yep…that was your brain on theta, too.

There’s also the delta range (1.5-4Hz) of brain waves which occur when you’re experiencing deep, dreamless sleep. This one, you probably don’t recall ;-)

Chasing Some Deep Relaxation

If your brain feels like it’s stuck in an anxious Beta state, and you’re having trouble shifting down into a more relaxing, meditative, alpha state of consciousness, put on your headphones or earbuds, and feed your brain some binaural beats: Infinite Bliss with Stereo Binaural Beats.

In the late 1950s, Nobel laureate Roger Sperry and Ronald Meyers discovered Split Brain Consciousness:

Initially they began experimenting with cats, and later proceeded to study monkeys. In 1961 the first human patient was subject to the split brain surgery.

The procedure worked well as a “cure” for patients who suffered from severe epilepsy and did not respond to anti-epileptic drugs. It was soon discovered that patients who had a commissurotomy had some interesting difficulties. Patients were not able to communicate information from one hemisphere to the other, almost as though they now had two separate brains.

Besides popularizing the word “commissurotomy,” Sperry and Meyers made evident that the human brain is actually a marriage of two separate brains — a left brain and a right brain — each capable of functioning alone, each with unique abilities. For example, the right brain excels at recognizing the human face and performing visual-motor tasks, but is a terrible reader. And the left brain has a knack for language and speech.

By the early 1960s, Roger Sperry was performing his most famous experiments into split brain consciousness with one of his students: Michael Gazzaniga.

In the following video, Alan Alda visits the research lab of Michael Gazzaniga, and discovers there’s nothing quite like seeing split brain consciousness in action:
