Brainwave study sheds light on cause of 'hearing voices'

Department of Defense Fiscal Year (FY) 2010 Budget Estimates May 2009, USA

``` Silent Talk (U) Silent Talk will allow user-to-user communication on the battlefield without the use of vocalized speech through analysis of neural signals. The brain generates word-specific signals prior to sending electrical impulses to the vocal cords. These signals of “intended speech” will be analyzed and translated into distinct words, allowing covert person-to-person communication. This program has three major goals: a) to attempt to identify electroencephalography patterns unique to individual words, b) ensure that those patterns are generalizable across users in order to prevent extensive device training, and c) construct a fieldable pre-prototype that would decode the signal and transmit over a limited range. ``` https://commons.wikimedia.org/wiki/File:Fiscal_Year_2010_DAR...
