We saw a lot of Anthony Lee and his tDCS experiments back around 2012-13. He popped up on YT recently and I’m happy to share his update.
The device he mentions near the end of his video is the Chattanooga Dual-Channel Iontophoresis Device which is also available at Caputron.
What a couple of days. First the New Yorker, now PBS tv! If you’re new to tDCS I’d caution you to note that Marom Bikson, one of the leading tDCS researchers in the world, is quoted below as saying ‘perhaps’, as in perhaps it improves brain function. Also, in the section where Andy McKinley is able to dramatically increase reporter Miles O’Brien’s performance of a vigilance task, ask yourself if you really have a need to improve your ‘Where’s Waldo’ score. Unfortunately, the piece doesn’t go into the use of tDCS as a tool to fight depression, which in my opinion, has come closest so far to a verifiable effect borne out by much clinical research. My point is simply that it’s early. We don’t have our tDCS ‘killer app’ yet. Stay tuned!
MILES O’BRIEN: But step aside, grande latte. There’s a new kid on the block.
MAROM BIKSON: So, current is going to come out of the device to the electrodes on your forehead and it’s going to flow through your head.
MILES O’BRIEN: Biomedical engineer Marom Bikson at the City College of New York is prepping me for a dose of transcranial direct current stimulation, or TDCS, a jump-start for my brain.
MAROM BIKSON: It can make the brain perhaps function information more effectively and therefore make you, let’s say, better at things. Or it can make the brain more likely to undergo plasticity, more malleable, more able to learn.
MILES O’BRIEN: A human brain has 100 billion nerve cells or neurons. Neurons are networkers. They make multiple connections with each other via synapses. We have about 100 trillion of them. All of this runs on electricity that we generate ourselves.
MAROM BIKSON: Now, this was the montage that we tried on you.
MILES O’BRIEN: It turns out each of our neurons is a microscopic battery with a-tenth of a volt of electricity. When we’re using them to remember things or do math or write this story, they fire electrical spikes.
MAROM BIKSON: When we’re adding electricity to the brain with TDCS, instead of a tenth of a volt, we’re producing a 1,000th-of-a-volt change, so it’s not enough to trigger a spike. It’s not enough to generate a spike, but it’s enough to modulate the spikes, to maybe get more spikes or to get less spikes.
And in this video Miles gets to fly a helicopter simulator before and after using tDCS.

[Update 1/17/13] tDCS for Mood Enhancement; Stimulation Causes Euphoric Opioids.
We met Anthony of GetLimitless.com, earlier on the blog. Here’s his recent YouTube update.
Anthony Lee shared the results of his most recent tDCS experiments on Reddit the other night (9/8/12). Using the Cambridge Brain Science Challenge (a set of four tests), he charted his scores over a two month period, comparing results with and without tDCS applied. Check out the video, and if you have questions for Anthony, post them to his Reddit thread.
[Update: Anthony also has a forum for Get Limitless.]
Anthony channels our inner lab rat on his fascinating YT channel. It doesn’t get any more DIY than this!
Towards the end of the video, Anthony explains why he switched to a manufactured device. You can follow Anthony on Twitter @GetLimitless and check out his blog, GetLimitless.com.
