Abstract
An ongoing pain detection system and method are provided. The method includes obtaining imaging data from patient using functional near-infrared spectroscopy from at least one cortical region of the brain of a non-responsive patient and observing power spectral density variations in the signal. The measured imaging data is compared with patient pain based on control data to recognize ongoing pain in the non-responsive patient.
