Outline of Final Research Achievements

Functional near-infrared spectroscopy (fNIRS) is a non-invasive imaging technique of the human brain hemodynamics. However, direct cortical measurement using fNIRS has yet to be realized.
We developed functional Near-infrared Cortical Imaging (fNCI), which enables the measurement of cortical hemodynamics directly from the brain surface with higher spatial resolution. We validated the fNCI system using miniature pigs. fNCI successfully detected the somatotopy of pig nostril sensation, as assessed in comparison with concurrent and sequential SEP measurements on the same stimulation sites.
Our new technique can measure the cerebral activities directly from the cortical surface with higher spatial resolution than that of the transcranial fNIRS. This study provides a clue for investigating the theoretical and technical principles of NIRS and possible application of our technique for direct cerebral blood flow monitoring during the human brain surgery.
