Description
Shunpei Yamamoto and six co-authors report a clean negative result for an ear-stimulation gadget in a 2026 paper. Zapping the ear's vagus nerve is said to release noradrenaline in the brain, and that chemical helps people stop a movement mid-flight. If the gadget worked, stopping should sharpen.
Twenty-four young men did a stop-signal task before and after half an hour of real or sham stimulation, in random order. A spit marker confirmed the real zaps did stir the chemical system. Yet stopping speed did not budge in either condition. The title says it plainly: no effect. Honest nulls like this keep clinics from buying hope without evidence.
