Response properties of duration-tuned neurons.A, Thresholds at BD as a function of BEF compared with the average behavioral audiogram of E. fuscus(solid line) from Koay et al. (1997). B, Cells with similar BEFs have a wide range of BDs. C, BD plotted against median first spike latency with regard to stimulus onset. Solid line, 1:1 line. D, BD as a function of the average number of spikes per stimulus, an indicator of response burst duration (r = 0.136;p = 0.2690).
