TL;DR: A near‐infrared spectroscopy (NIRS)‐based system that recognizes pleasant and unpleasant human emotions based on cerebral blood flow (CBF) in order to understand the minds of patients whose brain function is severely impaired is developed.

116. Anterior prefrontal activity associated with pleasant and unpleasant emotions: A study with event-related near-infrared spectroscopy
Yoko Hoshi,Jinghua Huang,Shunji Kohri,Yoshinobu Iguchi,Masayuki Naya,Takahiro Okamoto,Shuji Ono +6 more
TL;DR: A patient complained of numbness and pain of the hands and leg weakness from six years later at age 67, but could gait with cane independently and draw picture with intention tremor, suggesting a diagnosis of demyelinating neuropathy.

TL;DR: Two studies examined activity-dependent changes in the Hb oxygenation state in the somatosensory cortex of the rat brain during contrateral tibial nerve stimulation and in the occipital regions of human neonates during photic stimulation by using a near-infrared spectroscopy instrument.

TL;DR: The results imply that an increase in regional cerebral blood flow occurs because of stimulation specific to the visual cortex and that the increase in deoxygenated hemoglobin observed in theVisual cortex of the neonatal brain is attributable to venous dilation.
Quantitative evaluation of the relative contribution ratio of cerebral tissue to near-infrared signals in the adult human head: a preliminary study.
TL;DR: The present method opened the door to the possibility of selectively obtaining optical signals attributed to cerebral tissue by estimating the contribution ratio of the cerebral tissue to optical signals at the probe distances of 2, 3 and 4 cm.
