Who Needs A Psychiatrist When You’ve Got An iPhone?

Okay, sure the headline might have been a bit of an exaggeration, but it’s a (somewhat) serious question.

Here’s why.

Despite how amazingly complex is our brain function, it can be easily fooled and made to go along with the plans of others. For instance, if you smile at someone, odds are that that person will smile back. If you smile, you will feel better.

It should be the other way around. That is, if you feel good, you smile. And that’s true. You do. But it seems as if the mere physical act of twitching a few facial muscles is enough to fool the brain into thinking that, “If I’m smiling, I must be happy so I’d better start the happy time now.”

Which is the thinking behind MoodTune. According to the developer, Harvard psychiatrist Diego Pizzagalli, if you turn on MoodTune for about 15 minutes a day, play some games in the app, it’s possible you can lift yourself out of depression. It’s possible, Pizzagalli said, this app could be all the treatment a depressed person needs. No meds. No talk therapy. Just an iPhone app.

Pizzagalli started working on depression in 1999 and released some of his most important papers in 2001. The papers focused on “biomarkers,” signals of response in the brain to antidepressants and psychotherapy. Take a peek inside the brain, and you can see areas light up–or fail to light up–in response to treatments. Whether an area lights up or not predicts, with considerable accuracy, whether a treatment works, he says.

So, the thinking goes, what we if we illuminate those regions another way? The brain could readjust appropriately without the need for a pill. The anterior cingulate cortex is associated with depression and also works when snap decisions need to be made, Pizzagalli says, so perhaps having someone make snap decisions would help treat depression. He developed desktop software in his lab to test it out and was happy enough with the results to delve deeper into the technology.

And there’s the whole thing with the physical act of smiling making us feel happy. The thinking here is that it doesn’t matter what causes these specific areas of the brain to light up. If they light up, you feel less depressed.

I don’t know about you dudes, but I find that idea rather fascinating. It speaks to a sort of hacker mentality, but working in neurons instead of silicon chips. I think it’s sort of like an extension of behaviorist approaches to therapy. Behaviorists don’t care why you do something if the thing is what you want to stop. They just work on stopping the behavior and feel like that will take care of the underlying problem as well. In a nutshell. Generally speaking.

This is some really strange, but very cool stuff, very next-level thinking. My concern, though, arises from an analogy. If you’ve got a car tire that keeps going flat, you go out and get a new tire. Problem solved. You don’t care why it went flat because you’ve got a new tire and all is good. But what if the reason your tire kept going flat was because you kept parking next to a sharp bit of curb and it would scrape against the tire, causing it to gradually lose air. Pretty soon, you’re going to need another new tire because the underlying problem is still there.

Think of that like the brain. You’re seriously depressed. You treat this by tricking your brain into lighting up some key anti-depression areas by playing some games. You feel better. But the root cause still is there, yeah? Won’t the depression come back? Keep coming back?

I guess that’s why they research these things. We keep asking questions and they keep trying to find the answers.

I picked this information up from an interesting article at Popular Science. You might want to go over there and read the whole thing. It’s really absorbing. I know I learned some things, and that’s always good.

Progress? What Progress?

by Richard

Let me apologize right up front for this one, dudes. More than likely, I’ll be the only person who actually cares about this bit, but it’s something that’s been dragging on my brain for a while.

Here’s the deal. In writing about the Game of Thrones HBO series, I started thinking about one of the tropes of a lot of epic fantasy fiction like this.

Most fantasy fiction has a feeling of deep time. That is, things have been happening for thousands of years. And, for thousands of years, things have been mostly the same. That is, there are knights and serfs and lords in the current time and, hundreds, maybe thousands of years before, there were knights and serfs there as well.

The problem I see with this is, really, where’s the progress? I mean, seriously, the age of knights in our own world lasted — maybe, at best — a couple of hundred years in the Fourteenth and Fifteenth centuries.

And then we moved on. We went through the Renaissance and the industrial revolution and the silicon age and the space age and all the rest. We’ve made progress. Whether for good or ill, I’m not going to say, but we have changed and our society has grown. Knights are part of the past, not the present.

In fantasy fiction, like Game of Thrones or Lord of the Rings, the fictional citizens aren’t so lucky. Their societies don’t advance. They get stuck in the past and we, as readers, are content.

Well, not me. Not any more. Seriously. I want fantasy fiction that shows some societies can advance and still retain the elements that make for good fantasy fiction. Is that even possible? Or are we fantasy fiction lovers doomed to an eternity of knights and serfs, never knowing change, never finding out what tomorrow brings?

Who knows? Maybe one of us will have to write it for ourselves.

DNA Shines Through

All right, now this is just too cool. It turns out that scientists have found a way to turn strands of DNA (that’s the genetic material in your body that tells you how to be you) into fiber optic cables. Of course, fiber optic cables are what we use to send packets of light down twisty, turny channels and get from one place to another.

I know this has absolutely no relationship to fatherhood, family or suchlike, but I think it’s just too cool not to pass along.

If this discovery pans out, we could be seeing strands of DNA used on optical computers, which perform calculations with light rather than electricity, or artificial photosynthesis systems that could some day replace what we use for solar power. Basically what they’re doing is to combine a single strand of DNA with molecules called chromophores, which can absorb and pass on light.

“The result is similar to natural photonic wires found inside organisms like algae, where they are used to transport photons to parts of a cell where their energy can be tapped. In these wires, chromophores are lined up in chains to channel photons.”

I mean, come on! How is this not the coolest news of the week? We’re actually using organic parts to replace the silicon hardware we’ve been using since computers began. Once more, the future has bled through into the present.
