Extended Data Fig. 4: Amplification effect was robust.

Box and whisker plots show the baseline subtracted responses to 0.2 and 0.6 ml of juice, as in Fig. 3b, but applied to all 34 neurons that were significantly modulated by value. * indicates p < 0.05, ** indicates p < 0.01, N = 34 neurons, Wilcoxon signed-rank test, Bonferroni corrected for multiple comparisons. Box and whisker plots show, median (line), quartiles (boxes), range (whiskers), and outliers (+).
