Distribution of 16 tastants in a 3-D space resulting from multidimensional scaling. The distribution was calculated with Pearson correlation coefficient between stimuli across 40 CT fibers. The stress value is 0.047. The top plot shows that the sweeteners before lactisole formed a tight group further away from the non-sweet stimuli than after lactisole. The results suggest that lactisole diminishes the taste difference between sweeteners and other tastants.
