Information Transmission in the Auditory Brainstem Figure 6. Analysis of receptive field properties and first-spike latencies. Panels A and B illustrate scatter plots of Dfmax-vs.-CF functions for chinchilla and cat VCN neurons, respectively. Straight continuous lines display a linear fit to the data. Thick dashed line in panel A represents a fit to similar chinchilla ANF data [9]. DRmax-vs.-CF curves for chinchilla and cat neurons are displayed in C and D, respectively. Number of neurons (N) is indicated in each panel. A scatter plot of sFSL as a function of CF for ANFs (red dots) and high-sync neurons (filled triangles) in cat is in panel E. doi:10.1371/journal.pone.0044286.g006 Results in Fig. 1 indicate that high-sync neurons carry information about the stimulus waveform with higher distortion than ANFs. Period histograms obtained from responses of ANFs to single tones, such as those in Fig. 1, have a more sinusoidal shape than those computed from responses of high-sync neurons. Neurons with the highest THD values in Fig. 1 had the lowest CVs. Results in Fig. 1 indicate that high-sync neurons carry information about the stimulus waveform with higher distortion PLOS ONE | www.plosone.org 10 September 2012 | Volume 7 | Issue 9 | e44286
