An fNIRS Research on Prefrontal Cortex Activity Response to Pleasant Taste

Abstract

Functional Near-Infrared Spectroscopy (fNIRS), as a non-invasive neuroimaging technique, was used to monitor the activation of prefrontal lobe on human brain during sweet taste processing. The primary aim of the present study was to find the region of interest (ROI) which is related to sweetness, and make further understanding of the central organization of taste. Based on event-related design, the experiments were performed with 16 volunteers by sweet taste stimulus. It was confirmed that the prefrontal cortex (PFC) is involved in sweet taste processing and fNIRS provided an alternative way for studying taste-related brain function under more natural conditions. This study might be effective for detecting the accession area in the cortex of sweet taste and helpful for studying on human feeding and taste disease like taste dyspepsia or disorder.

Assessment of Prospective Memory using fNIRS in Immersive Virtual Reality Environment

“…Previous studies attempt to eliminate the motion noise from data by employing various techniques, such as motion-noise filtering from raw data [27]. Our study attempt to reduce motion noise by forcing participant to remain in a swivel chair in order to prevent large body motion.…”

Trial Analysis of the Relationship between Taste and Biological Information Obtained While Eating Strawberries for Sensory Evaluation

“…This procedure was constructed based on previous studies [ 33 , 35 ]. Similar to the previous study [ 36 ], the mouthwash was performed with pure water at a constant temperature. In this study, we calculated fNIRS features, as explained in “fNIRS data”, when the participants bit and swallowed the strawberries.…”
