IEEE Spectrum magazine published an excellent deep and engaging look at how electricity is now being used to cure, or at least relieve, severe cases of depression. The techniques involve electromagnetically tweaking specific parts of the brain via implanted electrodes, current, or magnetic fields. (Previous posts on the subject here
, and here
. I also wrote about it in Popular Science
in 2004.) The devices range from a "pacemaker" for your brain to a transcranial magnetic stimulator (seen here) that is used for just minutes each day but can alter your brain in the long term. From the article:
One problem with (neuropharmaceuticals) is that drugs work everywhere in the brain that their chemical target exists, regardless of whether those parts have anything to do with depression or any other disease, and that leads to side effects. Prozac, for example, has been known to reduce sex drive and can cause insomnia. Another problem is that brain chemistry varies from person to person, so no single drug will work in everyone.
The shared goal behind the new electromagnetic therapies, on the other hand, is to use electricity itself to restore the signaling, ideally, only in those parts of the brain affected by disease. Decades ago, neuroscientists demonstrated that electrically stimulating a neuron alters, in the long term, the strength of its connections to other neurons–making an electrical signal from one neuron more likely or less likely to jump to the next neuron. Though little is known in detail about how the new therapies work, it's likely that, to varying degrees, they depend on that phenomenon.
Coming after improvements to Firefox and continued unease at Google’s life-pervading insight, this image is outperforming the ███████ ████ Virality Control Group today (via). It got me thinking about all the promises that were made. Here’s the earliest article in Google News to contain “Big browser” in its headline, published by Time Magazine on Nov. […]
The WiFi232 is a traditional old-timey old-schooley Hayes-compatible 300-115200 baud modem, no wider than its own parallel DB25 port. Automatically responds with a customizable busy message when already in a call. The killer app seems to be using it to get internet onto ancient retro portables like the TRS-80 Model 102, but it’s been put […]
Most tech-media takes on the iPhone’s 10th anniversary are bland and self-congratulatory, but I like Tom Warren’s at The Verge. He laments how Apple’s pocket computer killed his inner nerd. As a youngster, he’d be constantly tearing down and building computers, even in the sweltering heat of summer. But now… …All of that tinkering and […]

The current web development landscape is rife with buzzwords and technology that gets abandoned almost as soon as it’s made. If you’ve never written a line of code before, it can be hard to figure out what’s coming, what’s here to stay, or how to get ahead.This Beginner Web Development Bundle is a great place […]
