Computer-brain interface

As software running on computer, mental activities of human brain may entry a dead loop too. Computer-brain interfaces give computers special channels to detect and interfere to interrupt unwanted thoughts which induce unpleasant intrusive thoughts and uncontrollable worry. In the present study, we intend to develop a noninterference and non-wake-up solution to detect and interrupt those unwanted thoughts which extend the transition from waking to sleeping. When an appropriate stimulus serial is given by this embedded computer according to subject brain state, it is possible that inhibition of the fluctuation-thought sources would be sustained until the sources are inactivated finally. The most important part of our solution is a small, wrist-watch like embedded computer which is based on VxWorks real time operation system and ARM processor. The operations of computer-brain interface are all completed by this computer which is noninterference and non-wake-up. By using this novel solution to interrupt unpleasant intrusive thoughts and excessive and uncontrollable worry during the pre-sleep period, in small sample trials, we have improved the measurement precision of sleep onset from more than ten minutes to about 6 seconds, and controlled unwanted thoughts efficiently.
