Have a look at the science behind DARPA research investigating the possibility of enhancing memory using tACS. Dr. Vince Walsh is the lead investigator. Elise Hu and team from NPR reporting.
In a multi-year study at the University of New Mexico, volunteers received a fraction of 9-volt battery’s worth of electrical stimulation to their scalps while they slept at the lab. When they woke up, they were asked to play a video game they had learned the day before. Turns out that subjects were significantly better at it after the night spent in the lab.
An email from Michelle Pearson at the NIH (because I had signed up for the online version of the workshop) alerted me today to a trove of TES (Transcranial Electric Stimulation) info being made available to us. Presenter slides (in PDF form) from the workshop were available for download. Because the download process was pretty wonky, involving many clicks and declined logins to Dropbox I thought to make them available here as well.
