DARPA has selected two universities to initially lead the agency’s Restoring Active Memory (RAM) program, which aims to develop and test wireless, implantable “neuroprosthetics” that can help servicemembers, veterans, and others overcome memory deficits incurred as a result of traumatic brain injury (TBI) or disease.
Understanding the anatomical structure and function of the brain is a longstanding goal in neuroscience and a top priority of President Obama’s brain initiative. Electrical monitoring and stimulation of neuronal signaling is a mainstay technique for studying brain function, while emerging optical techniques—which use photons instead of electrons—are opening new opportunities for visualizing neural network structure and exploring brain functions.
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.
Despite recent advances in technology for upper-limb prostheses, artificial arms and hands are still unable to provide users with sensory feedback, such as the “feel” of things being touched or awareness of limb position and movement. Without this feedback, even the most advanced prosthetic limbs remain numb to users, a factor that impairs the limbs’ effectiveness and their wearers’ willingness to use them. In a step toward overcoming these challenges, DARPA has awarded prime contracts for Phase 1 of its Hand Proprioception and Touch Interfaces (HAPTIX) program.
A new DARPA program aims to investigate the role of neural “replay” in the formation and recall of memory, with the goal of helping individuals better remember specific episodic events and learned skills. The 24-month fundamental research program, Restoring Active Memory Replay or RAM Replay, is designed to develop novel and rigorous computational methods to help investigators determine not only which brain components matter in memory formation and recall but also how much they matter.
