A new DARPA program aims to develop an implantable neural interface able to provide unprecedented signal resolution and data-transfer bandwidth between the human brain and the digital world.
The interface would serve as a translator, converting between the electrochemical language used by neurons in the brain and the ones and zeros that constitute the language of information technology. The goal is to achieve this communications link in a biocompatible device no larger than one cubic centimeter in size, roughly the volume of two nickels stacked back to back.
The program, Neural Engineering System Design (NESD), stands to dramatically enhance research capabilities in neurotechnology and provide a foundation for new therapies.
“Today’s best brain-computer interface systems are like two supercomputers trying to talk to each other using an old 300-baud modem,” said Phillip Alvelda, the NESD program manager. “Imagine what will become possible when we upgrade our tools to really open the channel between the human brain and modern electronics”.
Among the program’s potential applications are devices that could compensate for deficits in sight or hearing by feeding digital auditory or visual information into the brain at a resolution and experiential quality far higher than is possible with current technology.
Neural interfaces currently approved for human use squeeze a tremendous amount of information through just 100 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.
Achieving the program’s ambitious goals and ensuring that the envisioned devices will have the potential to be practical outside of a research setting will require integrated breakthroughs across numerous disciplines including neuroscience, synthetic biology, low-power electronics, photonics, medical device packaging and manufacturing, systems engineering, and clinical testing. In addition to the program’s hardware challenges, NESD researchers will be required to develop advanced mathematical and neuro-computation techniques to first transcode high-definition sensory information between electronic and cortical neuron representations and then compress and represent those data with minimal loss of fidelity and functionality.
To accelerate that integrative process, the NESD program aims to recruit a diverse roster of leading industry stakeholders willing to offer state-of-the-art prototyping and manufacturing services and intellectual property to NESD researchers on a pre-competitive basis. In later phases of the program, these partners could help transition the resulting technologies into research and commercial application spaces.
The US Defence Advanced Projects Agency (DARPA) has awarded a Northrop Grumman-led team a project to build a full-scale technology demonstrator system of a medium-altitude, long-endurance UAV called Tern, designed to use forward-deployed small ships as mobile launch and recovery sites. The first two phases of Tern successfully focused on preliminary design and risk reduction
The US Defense Advanced Research Projects Agency (DARPA) plans to replace Global Positions Systems with Atomic Clocks with Enhanced Stability (ACES). “All of our modern communications, navigation and electronic warfare systems, as well as our intelligence, surveillance and reconnaissance systems, depend on accurate time-keeping,” said Lutwak, who will oversee the new program, called Atomic Clocks with Enhanced Stability (ACES) Wednesday in an official press release
DARPA is working on a developmental time machine using the peripheral nerve stimulation to enhance learning processes as a substitute for drugs to treat diseases and accelerate healing and also to control advanced prosthetic limbs and restore tactile sensation to their users. The new program Targeted Neuroplasticity Training (TNT), seeks to advance the pace and effectiveness of a specific kind of learning—cognitive skills training—through the precise activation of peripheral nerves that can in turn promote and strengthen neuronal connections in the brain, DARPA said in a statement Wednesday
