The energy, focus and multitasking ability of sleep deprived people can be boosted by a handheld device that delivers an electric current to the neck, a study has found. Researchers led from US-based firm Infoscitex tested on 20 sleep deprived adults a device originally designed to treat headaches that stimulates the vagus nerve. The vagus nerve — which is the longest in the autonomic nervous system — passes signals between the brain, digestive system and other organs. According to device designer gammaCore, their vagal nerve stimulator delivers a mild shock, felt as a deep vibration in the neck and slight muscle contractions. The shocks from the gammaCore device are very mild.
