The U.S. Defense Advanced Research Projects Agency (DARPA) is working with seven U.S. universities and elements of the Air Force and Army on research that seeks to stimulate the brain in a non-invasive way to speed up learning. This Targeted Neuroplasticity Training (TNT) will explore using peripheral nerve stimulation to enhance learning processes in the brain. Announced in March, the Targeted Neuroplasticity Training, or TNT, program has begun to explore the safest and most effective ways to activate a natural process called "synaptic plasticity." Plasticity is the brain's ability to strengthen or weaken its neural connections to adapt to changes in the environment. For TNT Program Manager Dr. Doug Weber, such plasticity is about learning. "We're talking about neural plasticity, or how the neurons, which are the working units in the brain, how their function changes over time as we train on new skills," he said. Targeted Neuroplasticity Training TNT research focuses on a specific kind of learning called cognitive skills training. People use cognitive skills to do things like pay attention, process information, do several things at once, detect and understand patterns, remember instructions, organize information and much more. TNT researchers will try to identify physiological mechanisms that might allow them to enhance natural learning by electrically stimulating peripheral nerves -- those that connect neurons in the brain and spinal cord to organs, skin and muscles -- to make the brain more adaptive during key points in the learning process, according to a DARPA announcement about TNT. "The mechanisms underlying this enhancement are not well understood," Weber said, "but we believe that neurostimulation boosts the release of neurotransmitters such as acetylcholine, norepinephrine and others that play a role in modulating cognitive processes related to learning." There's probably no single "silver bullet," he added, "but rather there are multiple processes involved. Thus, a primary goal of TNT is to tease apart the various mechanisms to understand the links between neurostimulation, neurotransmitter release, and resulting changes in plasticity." To activate the peripheral nerves, researchers will compare non- invasive electrical stimulation through the skin with an invasive form of stimulation -- using an implanted device -- to see which is more effective. But Weber envisions a device that can promote plasticity by using electricity to stimulate peripheral nerves through the skin, DARPA says. The program is starting with the basic science of brain plasticity and will conclude, if the research is successful, with human trials in healthy volunteers. This Targeted Neuroplasticity Training concept diagram demonstrates how the Defense Advanced Research Projects Agency (DARPA) program will explore using peripheral nerve stimulation to enhance learning processes in the brain. DARPA will fund research teams from seven universities and partner with elements of the Air Force and Army to execute the program. (DARPA) DualSeal ™ Chest Seal The DualSeal™ Chest Seal Two-Pack puts the proven success of our Wound Seal™ hydrogel dressing in a smaller, more convenient package. Featuring two 3.75" x 3.75" occlusive seals, the DualSeal™ Chest Seal pack provides the ability to cover two wounds without carrying a larger pouch. With easy to peel tabs, each DualSeal™ Chest Seal can be applied over an open wound or can be used to seal over a puncture chest wound. Custom foil packaging provides 5 years of sterile shelf life and is rugged enough to survive in any environment from -10°C to 40°C.
