Jolyon Jenkins meets the people zapping their brains with DIY electrical devices, lasers and electromagnets. They want to learn faster, dream better, and even have spiritual experiences.

Some of it might even work. There's evidence that putting a weak electric current through your skull can help you learn, and induce a "flow" state. The US military is experimenting with devices that seem to help snipers improve their marksmanship. One woman who tried it says that what she found was that "electricity might be the most powerful drug I've ever used in my life."

Such talk is just what the garage experimenters want to hear. Real drugs are hard to get licensed, but many of the experimenters hope that a strap-on electrical head gadget will be able to give the same kind of effects, but without having to go through the regulatory hoops. There's money to be made, they hope, from early adopters who see their brains as just another device that can be improved through a bit of hacking.
