Fig. 3.

Coactive spheres across taste concentrations. (A) Heat maps depict the coactivity index of spheres based on data from narrowly tuned spheres for the cross-experiment decoding. Coactivity is expressed as an index of overlapping spheres across concentrations, where 0 indicates the absence of overlap and 1 complete overlap. (B) Heat maps represent the coactivity index based on classifications for intensity judgments. (C) Heat maps represent the coactivity index for pleasantness judgments. The main diagonal represents coactive spheres coding for the identical taste category across concentrations. Values outside the main diagonal indicate a switch in taste preference as a function of concentration.
