dc.description.abstract | Aim: The aim of this study was to evaluate the feasibility of a functional near infrared
spectroscopy (fNIRS) system, for quantification of the similarities and differences
in the spatial localization of cerebral hemodynamic activation, induced by visual
presentation of neutral, negative and positive valence emotional stimuli.
Method: Thirteen healthy subjects viewed neutral, pleasant and unpleasant pictures
from the International Affective Picture System (IAPS) database in a block design
experiment while the prefrontal cortical hemodynamic changes induced by emotional
stimuli were continuously recorded with a 20 channel fNIRS system that covered the
forehead region.
Results: Negative valence pictures induced higher hemodynamic activity in right
lateralized regions involving dorsolateral and orbitofrontal cortex, when compared to
neutral and positive valence stimuli (pFDR<0.05). Each stimulus condition induced a
distinct cortical activation pattern that could be identified with fNIRS.
Conclusion: Our findings support the notion that different basic emotions have
distinct localization and separable hemodynamic correlates in the prefrontal
cortex region, which can be detected with a mobile fNIRS system. The distinct
cortical hemodynamic activity patterns associated with each emotional state show
the potential of fNIRS technology for decoding and differentiating basic emotions
objectively and real time for future clinical and daily life applications. | en_US |
