A device called NeuroThera is being tested in clinical trials to treat stroke patients and other patients with brain injuries. The handheld device, about the size of a telephone receiver, delivers high-intensity infrared energy to a patient’s head when it’s held to the scalp. The idea is that the infrared energy delivered via laser will stimulate inactive mitochondria in brain cells — the small bits of protein that serve as power suppliers to cells. Once the energy-starved brain cells start receiving power again from the mitochondria, they should be able to resume function. More at WFTV Orlando
