My apologies for misreading. Yes, Algernon's Law motivates the research (in addition to "my brain is important and this is weird," and other motivations); but research shouldn't be focused on whether the mechanisms were available in the EEA unless that evidential node is among the low-hanging fruit, as far as ease of research and large likelihood ratios go.
There's been a bit of discussion about TDCS here on LessWrong. If you don't know what TDCS is here's an article from Technology Review.
Here's a company (soon) selling a DIY kit to build your own.
Here's a video from Journal of Visualized Experiments on how to administer TDCS.
Thoughts?
