DARPA plans to shrink brain interface and organ control electronics to the size of nerve fibers

Here is follow up news on various DARPA brain related projects

In May, Nextbigfuture reported that DARPA had $70 million in funding a project for brain implants for emotional mind control.

DARPA has a $79.8 million ElectRx project that aims to explore neuromodulation of organ functions to help the human body heal itself.

The body’s peripheral nervous system constantly monitors the status of internal organs and helps regulate biological responses to infection, injury or other imbalances. When this regulatory process goes awry due to injury or illness, peripheral nerve signals can actually exacerbate a condition, causing pain, inflammation or immune dysfunction. A number of difficult-to-treat conditions might be managed more effectively by precise modulation of the peripheral nervous system than by conventional medical devices or medications.

“The technology DARPA plans to develop through the ElectRx program could fundamentally change the manner in which doctors diagnose, monitor and treat injury and illness,” said Doug Weber, DARPA program manager. “Instead of relying only on medication—we envision a closed-loop system that would work in concept like a tiny, intelligent pacemaker. It would continually assess conditions and provide stimulus patterns tailored to help maintain healthy organ function, helping patients get healthy and stay healthy using their body’s own systems.”

Initiated in support of the President’s brain initiative, ElectRx (pronounced “electrics”) aims to develop new, high-precision, minimally invasive technologies for modulating nerve circuits to restore and maintain human health. ElectRx technologies are also expected to help accelerate scientific research aimed at achieving a more complete understanding of the structure and function of specific neural circuits and their role in health and disease. Potential targets include recently identified circuits involved in regulating immune system function, providing new hope for treating a range of inflammatory diseases, including rheumatoid arthritis, systemic inflammatory response syndrome and inflammatory bowel disease. ElectRx is also expected to improve peripheral nerve stimulation treatments for brain and mental health disorders, such as epilepsy, traumatic brain injury (TBI), Post-Traumatic Stress Disorder (PTSD) and depression

DARPA’s ElectRx program plans to develop technologies to restore and maintain healthy physiological status through monitoring and targeted regulation of signaling in peripheral nerves that control organ functions. Novel therapies based on targeted stimulation of the peripheral nervous system could promote self-healing, reduce dependence on traditional drugs and provide new treatment options for illnesses.
