Across-neuron patterns displaying net responses to the 15 stimuli and spontaneous firing rates in individual neurons in B6 (left) and 129 (right) mice. For each strain, S-, N-, and H-cells are placed together and in descending order of their responses to sucrose, NaCl, and HCl, respectively. The filled bars indicate that the response reached the criterion for significant excitation or inhibition, whereas the open bars did not. Responses are based on a 5 s evoked period. Stimuli are labeled on the right (abbreviations are as in Table 1).
