PREFRONTAL ACTIVATION DURING EMOTIONAL EXPERIENCE AS MEASURED BY NIRS

概要

To investigate brain activation in the prefrontal cortex (PFC) during emotionalexperiences, we examined blood oxygenation changes of healthy female volunteers byusing multi-channel Near Infrared Spectroscopy (NIRS). Results directly confirmedthat the PFC was activated during emotional tasks suggesting that the levels of oxy-Hbincreased significantly larger in negative periods compared with positive or neutral inthe bilateral dorsolateral PFC. There is a possibility that this brain area is associatedwith the regulation of negative emotion. Our results suggest that it may be possible toevaluate emotional changes using NIRS sensitively.
