Relationship of leading inhibition to BD, first spike latency, and duration filter characteristic. A, Duration of leading inhibition was significantly correlated with BD (r= 0.632; p < 0.0001; n = 32). B, Duration of leading inhibition was significantly correlated with median first spike latency with regard to stimulus onset (r= 0.646; p < 0.0001;n = 32). Each point is the average duration of leading inhibition measured across different NE tone durations with equal amplitude BD and NE tones. Solid line, 1:1 line.
