Stupid hair getting in the way of your functional near infrared spectroscopy (fNIRS) experiments? Good news! Researchers from Texas speaking at the Optical Society's (OSA) 94th annual meeting in New York have created a "brush optrode" with fiber tips designed to thread through hair to enhance scalp contact.
fNIRS is an optical technique that measures oxygen levels in the brain to chart neurological activity. The big advantage over something like an EEG is portability and cost, which means beter imaging of changes in cortical plasticity as a function of impairment severity, like in children with cerebral palsy.
