PCA results associated with the 40 °C trial. a) PCA analysis performed on the average temporal taste response across TTs identified four principal components which accounted for 85% of the variation in the data, the associated temporal responses are shown. b) PCA analysis performed on individual participant temporal taste responses identified four subgroups when plotting the time to peak of PC1 against PC2, these groups relate to the temporal responses identified in Fig. 4a.
