“BIOPAC Systems, Inc., announces new functional near infrared (fNIR) optical imaging systems to measure oxygen level changes in the prefrontal cortex of human subjects.  The fNIR system provides researchers with real-time monitoring of tissue oxygenation in the brain as subjects take tests, perform tasks, or receive stimulation. It allows researchers to quantitatively assess brain functions — such as attention, memory, planning, and problem solving — while individuals perform cognitive tasks.” [source]
