Another application has been tested for Transcranial Direct Current Stimulation (tDCS)—a “bioelectric medicine” device. This time it has been applied to curb bleeding. It may be particularly helpful with internal bleeding which is as life-threatening as external and harder to stop.
Applying the current to the vagus nerve which connects the brain to the vital organs “would then trigger the spleen to release blood-clotting platelet cells and send them to areas in need.” The device will be used in a clinical trial “as a treatment for postpartum hemorrhage (a leading cause of maternal death worldwide)”. And it “could theoretically be used … as a blood loss prevention strategy during surgery.”

Transcranial Direct Current Stimulation (tDCS), has been tested by the US military to enhance brain function. The article reports: “US military scientists have used electrical brain stimulators to enhance mental skills of staff, in research that aims to boost the performance of air crews, drone operators and others in the armed forces’ most demanding roles. …
“The technology is seen as a safer alternative to prescription drugs …
“But in a series of experiments at the air force base, the researchers found that electrical brain stimulation can improve people’s multitasking skills and stave off the drop in performance that comes with information overload.”
While this technology uses microcurrents, it is based on direct current. As a result, the use is recommended only as a medically supervised technology. Reported in The Guardian as: US military successfully tests electrical brain stimulation to enhance staff skills. November 7, 2016.
