Figure 2.
Odor mixture discrimination by component ratio generalizes to higher concentration probe stimuli. (A) Training stimuli (black filled circles) had fA + fB = 100. Test stimuli (red circles) were chosen such that fA + fB = 150. The training reward boundary is indicated by the magenta diamond. See Figure 1A for details. (B) Choices of one rat on training stimuli and test stimuli with higher concentration. The independent variable is the ratio fA/fB. Some training data points are not visible because they are hidden behind the corresponding test data points. (C) Choices of one rat on training and test stimuli. The independent variable is the single component fA.
