29. Smart dust:
Nanoparticles that can be employed as sensor networks for a range of security and environmental applications. Smart Dust for the brain is being proposed as the next step toward establishing a brain-computer interface. The system is officially called โ€œneural dustโ€ and works to โ€œmonitor the brain from the inside.โ€ The investment in neuroscience has received a 100 million dollar commitment via Obamaโ€™s BRAIN project, while Europe has committed $1.3 billion to build a supercomputer replica of the brain in a similarly comprehensive and detailed fashion as the Human Genome Project mapped DNA. The neural dust is interrogated by another component placed beneath the scale but powered from outside the body. This generates the ultrasound that powers the neural dust and sensors that listen out for their response, rather like an RFID system. Remote-controlled analysis of the human brain opens the door for remote mind control.
