Fig. 5.
Mean ± SE information conveyed by spike count (firing rate, H0) and a combination of spike count and the temporal characteristics of response (Hmax) at various response intervals. These intervals were (in ms): 100, 125, 200, 250, 500, 1,000, 1,500, 2,000, and 5,000. Each panel in this figure shows a different discrimination among stimuli: 3 concentrations each of NaCl and HCl (top), NaCl vs. HCl collapsed across concentrations (middle), and 3 concentrations each of NaCl and HCl and 5 NaCl–HCl mixtures (bottom). Arrow at the bottom of each plot indicates 2.0 s, the response interval that was chosen for more detailed analyses of temporal coding.
