9-Volt Nirvana [RadioLab]

The glory of sudden, instant, effortless personal development.  That was the enticement of RadioLab’s, 9-Volt Nirvana podcast episode.

Juice the brain; no more than a 9-volt battery. And suddenly, bam! You become an invincible sharp-shooter.  Firing away at virtual killers, bringing them down with perfect accuracy. Where minutes before the juice, you’re lying in a pool of virtual blood.

Or maybe your brain suddenly, quickly, picks out a 3D shark from an autostereogram. Where minutes before the juice, your eyes and mind only saw a jumble of colored images, smeared together.

Or maybe, studying vocabulary, you add some juice and the words are suddenly easy.

The episode is about transcranial direct current stimulation (tDCS), a process that promises to help us accelerate our learning, by zapping our scalp—and whatever brain cells lay beneath—with electricity.  According to the podcast, “Researchers claim that juicing the brain with just 2 milliamps…can help with everything from learning languages, to quitting smoking, to overcoming depression.”

RadioLab’s story enticed. Aren’t there places in our lives we’d like to do something better? Quicker? Easier?

Sniper-Training

It was Sally Adee, sniper-in-training, that drew me in.  Sally convinced her editors at New Scientist to fly her from London to Carlsbad, CA to test out tDCS. She went to Advanced Brain Monitoring, a group using tDCS to train snipers.

There, in a room using 360-degree training simulation tools, real sandbags and other props, holding an M4 assault rifle armed with a laser site and CO-2 cartridges to deliver a realistic kick-back, Sally ran through a simulation. First, without tDCS.

The simulation starts off slowly. She has time to react, to take her shots. And then, it gets chaotic. The Humvee in front of her explodes and killers come at her from every direction. It’s all too fast, she can’t decide. And at the end of the simulation, she’s taken down about 3 out of 20 suicide bombers.

Then they wire her up: attach one electrode to her right temple and another electrode to her left arm. They turn on the electric current. She’s put into the simulation again, only starting from the point where the Humvee was being blown up. And with the wires juicing her brain.

Her assessment of this second round is they’ve slowed things down; it’s not difficult, she can clearly see where the dangers are coming from and she picks off her targets. It ends, they unplug her, and she’s confused; she’s only been in the simulation a few minutes. She’s sure they didn’t give her a difficult simulation.

Then she looks at the clock: 20-minutes have passed. And, no, they hadn’t slowed it down or made it easy.

This time, with the juice, she’s scored a perfect 20 out of 20.

Bringing down “bad guys” makes this technology sound good. But what if someone was learning this skill to wreak destruction on an innocent community? Do we want that ability to be easily acquired?

Cheap Cost and Unknown Risks

But there may be no choice. The technology is there. It’s easy and cheap to build your own tDCS device, around $20 for parts at your local electronics store.  It’s hard to regulate. People are out there, self-applying it, experimenting by placing it on different parts of their brain, trying to figure out what helps, what doesn’t.  In reference to one fellow on YouTube talking about doing tDCS, the podcaster comments, “It’s like he’s playing Russian roulette with that thing.”

People have reported “loss of consciousness after using it…feeling burns…there was one report of someone going temporarily blind.”  In the comments posted below a tDCS TEDx talk by Maarten Frens in December 2013, one person warned, “I burned a dime size hole through my scalp today with only 8 aa batteries and eeg pads. This is dangerous!”

The device is a blunt tool, not a scalpel.  And there’s a theory, called “The Zero-Sum Theory of the Brain,” which says our brains and body are a system. If “juice” is sent to one area, it has to come from another area; enhancing one area is “by definition diminishing another.”

Is it Good? Or Bad.

For Sally, who acquired impressive shooting skills using tDCS, she admitted she valued some of the after-affects. She felt more confident driving and some of the critical voices in her head were quiet for several days. Those feelings were powerful and positive. But she was also worried. She was surprised how much she “craved doing it again.  It felt,” she said, “like a drug with no side effects. I don’t know if I’m going to get addicted to electricity…”

A deeper, philosophical question is raised by Soren Wheeler, Jad Abumrad, and Robert Krulwich, the show’s hosts. They ponder those moments when we’re “awake and present,” that feel like a gift from the universe.  What happens, they ask, when we can “order up” a state of mind; when “it’s an expectation” we “can create… on demand?”

“I think that the ‘gift’ versus ‘ordering it up’ is pretty deep to me,” says Soren. “I feel like, in a world where you order things up then you’re in a world where you think you deserve things or you think you’ve earned them or think other people haven’t. That’s a world that’s empty of true gratitude.”

Moving Slowly in a Fast World

The world feels fast: fast food, high-speed trains, supersonic planes. Tech companies move fast and break things. People want things now, resulting in instant Jell-O, instant messaging and Instant Pot.

I’m slow. I read slowly, write slowly, learn slowly. I’m thorough; detail-oriented.

This fault-line between my slow-motion style and the world’s fast-motion expectations sometimes leaves me feeling deficient, concerned I lack a societally-valued trait.

My discomfort intensifies when I try to learn something new. I plod through my learning while images of Neo from The Matrix appear, skills and knowledge insta-loaded into his memory.

I’ve wrestled with this aspect of my personality, being self-critical when I take too long to learn something, aching to speed things up.  Expecting something other than what is.

Dating and Baggage

When I was single and dating—a divorced adult with a child and more than one serially monogamous relationship in my backpack—the word baggage was often used.

Baggage: past experiences or long-held ideas regarded as burdens and impediments.

Burdens and impediments.

Not exactly a super-hero word in the world of adult dating. The sentence used to illustrate the word—the emotional baggage I’m hauling around—conjures up Pig-Pen from the Peanuts comic strip; the dirt and dust trailing behind him his emotional baggage.

Those Pesky Resolutions

January 1st. The first day of a new year. That day when we feel the potential of who we think we can be as we write our resolutions.  It’s that First Day of our Big Promise to Quit Something or Start Something.

It’s usually one or the other.  Stop drinking. Smoking. Swearing. Eating ice cream. Start going to the gym. Drinking more water. Reading more.

We choose things that promise we’ll become better, healthier people if we do them. Because, lord knows, if we accept ourselves as we are, how will we ever improve? We need motivation and surely these New Year’s Resolutions will motivate, yes?

Yet we fail miserably at New Year’s Resolutions.

Still we keep doing them. January 1 rolls around and we promise to stop or start various new behaviors and naively act like, this year, we’ll successfully stick to it for 365 days.

Here’s my thought on the New Year’s Resolution Custom.

Stop It.

Just quit.

Emotions [Invisibilia]

Podcasts are one of my favorite ways to get different perspectives on things and explore new ideas. This Invisibilia podcast on emotions is mind exploding. If you like podcasts, check this one out. If you experience emotions, same advice.

Pursuing Podcasts

If you think you know how emotions work, this podcast will turn your world upside-down.  Enough so that you may find yourself arguing that what’s being presented can’t be possible.

Before hearing this, I had a hope that we have more control over how we respond to things than we sometimes think. It’s one of the reasons I started meditating: to learn to not get hooked as much by emotions.

Yet it often feels as if an emotion takes me over, as if I have no “choice” in feeling something. But what if emotion is the interpretation of a physiological feeling? What if it’s a way our body tries to “make sense” of a sensation? What if we do have control?

That’s the idea this episode presents.
