Figure Lengend Snippet: A : fNIRS Montage created using the NIRSite software showing the source and detectors in their respective locations that cover bilateral frontal and parietal cortex B . Montage figure generated by the QT NIRS package in MATLAB showing the amount of good quality data for each channel in its location within the montage indicating a higher proportion of good quality data in the frontal channels than parietal channels C. Colored coded montage diagram showing how the channels that were aggregated into anatomical ROIs.

Article Snippet: For ROI-level analyses, channel-wise time series were aggregated into Brodmann Area (BA)-based regions (see and ) following the same preprocessing pipeline as the Task vs. Baseline analysis using the NIRS Toolbox in MATLAB.

Article Title: Unveiling plant protein astringency perception through neural and cellular responses

doi: 10.1038/s41598-025-23836-9

Figure Lengend Snippet: Illustrative overview of methodologies used to unveil the sensory, neural and cellular response to plant proteins. A combination of sensory trial with untrained human participants ( n = 100) using Rate-All-That-Apply, (RATA), a study of neural response in prefrontal cortex of human participants ( n = 34) measured using Functional Near-Infrared Spectroscopy (fNIRS) and cellular response measured using saliva-coated oral epithelium based TR146-MUC1 cell lines was used to unveil plant protein astringency mechanisms. The astringency is uniquely detected in the prefrontal cortex of the brain leading to negative tactile responses which resulted from physical binding of plant proteins with saliva bound to oral epithelium, inducing astringency perception. Ethical approval was obtained from the University of Leeds (MEEC 16–046 and PSYC-475) by the Faculty Ethics Committee, University of Leeds, UK.

Article Snippet: Data pre-processing and analysis was done using the NIRS Brain Analyzer Toolbox (operating in Matlab (MatLab 2023a, Mathworks), for pipeline of data processing see Supplementary Fig. .

Figure Lengend Snippet: Neural response of astringent pea protein formulations compared with tannic acid (a known astringent control). Schematic diagram ( a ) of the placement of detector (blue, D1-3) and source nodes (red, S1-8) spanning the right and left dorsolateral areas (F3, F4) and dorsomedial areas (Fz) of the dorsolateral prefrontal cortex (DLPFC). ( b ) Block averaged overall neural response of changes in Oxygenated haemoglobin (HbO) using functional near-infrared spectroscopy (fNIRS) are plotted at three times points between 0–60 s. when consuming non-astringent water (Water), low astringent, viscosity matched 5 wt% total protein pea protein concentrate (PPC5), 15 wt% pea protein concentrate (PPC15) and 0.8 wt% tannic acid (TA). Beta values are plotted from T-stat ( n = 34 participants) with the colour legend indicating magnitude of difference. A positive value (warm colours) reflects increase in HbO compared to baseline whilst a negative value (cool colours) reflects decreases in HbO. Rate-All-That-Apply (RATA) values are presented as bar and whisker plots with the interquartile range, minimum and maximum plotted for each sample in ( c ) astringency, ( d ) thickness, ( e ) sweetness and ( f ) creaminess presented as means and standard deviations of n = 34 with Bonferonni correction. Ethical approval was obtained from the University of Leeds (MEEC 16–046 and PSYC-475) by the Faculty Ethics Committee, University of Leeds, UK.

Figure Lengend Snippet: Anterior view of functional near-infrared spectroscopy montage and optode placement: four sources (S1–S4 represented by red circles) with 690 and 830 nanometer laser light and eight detectors (D1–D8 represented by dark blue circles). Light blue lines represent ten channels. Optodes were positioned in reference to the 10–20 EEG international coordinate system, covering the prefrontal cortex region with Fp1 referenced to Detector 5 and Fp2 referenced to Detector 4.
