The reduced blood supply starves brain cells of nutrients and over time they become damaged and die. Symptoms of the condition include loss of energy, lack of concentration and poor memory.

Monitoring the proper blood supply to the brain is crucial, not only to prevent neurological diseases but also to treat them. The parallel near-infrared interferometric spectroscopy technique, or ...
