Electrical stimulation to the brain speeds up learning

Air Force operator receiving transcranial direct current stimulation (TDCS) to accelerate learning.

By running a mild electric current through the brains of pilots during lessons, Air Force researchers have cut their personnel’s learning time in half.  Pilots were being taught how to identify targets using drones—the practice is increasingly important to modern warfare and one which, due to its difficulty, is holding back the deployment of drones. Caffeine and other stimulants have been tested to aid learning but none work as well as two milliamperes of direct current for 30 minutes to pilot’s brains during training sessions on video simulators.

Scientists Believe a Near-Death Experience is the Last Gasp of a Dying Brain

near death

Near-death experiences may be caused by a surge of electrical activity in the brain moments before death.

The mystery of why people ‘brought back from the dead’ report powerful spiritual experiences may have a biological explanation, according to experts.  Researchers who studied brainwaves of dying patients, found there was a surge of electrical activity in their brains just moments before their lives ended.
