DARPA’s brain implants will give you access to downloadable content and read your mind

DARPA (Defense Advanced Research Projects Agency) is working on a brain implant that can give the human brain immediate access to the digital world.

As part of DARPA’s Neural Engineering System Design (NESD) program, implantable neural interfaces will also serve as translators that convert the electrochemical language used by neurons in the brain into the ones and zeros that constitute the language of information technology.

“Today’s best brain-computer interface systems are like two supercomputers trying to talk to each other using an old 300-baud modem,” said NESD program manager, Phillip Alvelda. “Imagine what will become possible when we upgrade our tools to really open the channel between the human brain and modern electronics.”

DARPA imagine the implant will be used to inject sounds and images into the brain, but the immediate aim of the scheme is to provide unprecedented signals and data-transfer bandwidth between the human brain and the digital world.

To make this a reality, DARPA aims to recruit leading figures from disciplines such as neuroscience, synthetic biology, low-power electronics, photonics, medical device packaging and manufacturing, systems engineering, and clinical testing.

DARPA does already have some experience of inserting implants into human brains.

Last year, it was reported that the defence agency had started implanting computer chips into soldiers’ brain tissue, on their return from campaigns in Afghanistan and  Iraq, to help regulate the nervous system and to alleviate symptoms of a variety of conditions from post-traumatic stress disorder to arthritis.

However, current brain implants try to squeeze lots of information through a small number of channels, with each channel aggregating signals from tens of thousands of neurons at a time. The result is noisy and imprecise.

In contrast, the NESD program aims to develop systems that can communicate clearly and individually with any of up to one million neurons in a given region of the brain.

Computer system transcribes words users “speak silently”

MIT researchers have developed a computer interface that transcribes words that the user verbalises internally but does not actually speak aloud. The wearable device picks up neuromuscular signals in the jaw and face that are triggered by internal verbalisations — saying words “in your head” — but are undetectable to the human eye.

Drones could be used to penalise bad farming

A report by a coalition of environmental campaigners is arguing squadrons of drones should be deployed to locate and penalise farmers who let soil run off their fields. Their report says drones can help to spot bad farming, which is said to cost more than £1.2bn a year by clogging rivers and contributing to floods.
