Thread: Published in Nature Neuroscience: 77% induction rate with electrodes on the scalp at 40 Hertz

It is the tACS current that is being directly detected. And the brain state does go back to normal, so all we have to go on for now is the subjective statement. It would be interesting to see a longer recording with the power bands turned on.

Not sure what they cost or how to get one as a mortal, will see if I can find out.

The following blog from July 18, 2012 mentions prices for a couple of tDCS devices. Prices for tACS devices are probably similar.

Device | DIY tDCS - Part 2

There are presently only two stand-alone devices that produce tDCS. They are: the Eldith DC Stimulator by Neuro Conn, of Germany, which sells for €3000 (about $4,000US) and the CESta, by Mind Alive Inc., of Canada, which sells for $350US. [now $450. + accessories]

Wouldn't buy one for $4000, but maybe for $450.
