Researchers wake monkeys by stimulating ‘engine’ of consciousness in brain

A small amount of electricity delivered at a specific frequency to a particular point in the brain will snap a monkey out of even deep anesthesia, pointing to a circuit of brain activity key to consciousness and suggesting potential treatments for debilitating brain disorders.

Injectable, flexible electrode could replace rigid nerve-stimulating implants

Neuromodulation therapies can reduce epileptic seizures, soothe chronic pain and treat depression. Now, a significant advance could dramatically reduce their cost, increase their reliability and make them much less invasive.
