Basic features of the dataset. a Normalized response matrices. In these matrices, the mean response of each neuron (depicted in one row) is normalized to a value between −1 and 1. Each column corresponds to one stimulus. Non-significant responses are set to 0. Each matrix corresponds to all units recorded in a single strain. Raw and normalized matrices with significant responses are shown in Additional File 1. b Percent of neurons with significant responses to each of the stimuli. c Normalized response magnitude. In this representation, each neuron’s responses are normalized as in panel a. This normalization ensures that all neurons have the same contribution to the population response magnitude. Vertical error bars represent standard errors of the mean. Horizontal lines represent significant differences among stimulus pairs using a one-way non-parametric ANOVA (Kruskal-Wallis test). Broken lines indicate p values below 0.05, while solid lines indicate values below 0.01. See Additional File 2 for specific p values for this and all other pairwise comparisons
