Figure Lengend Snippet: Poststimulus time histograms (PSTHs) of TB fibers (A–L) and MNTB neurons (M and N) in response to short tones at characteristic frequency (CF). The CF and sustained rate, calculated over a 10- to 25-ms window, are shown above each PSTH. A–C: examples of primary-like (PL) responses at suprathreshold levels of 40, 22, and 37 dB. D–F: primary-like-with-notch (PLN) responses at 30, 28, and 32 dB. G–I: phase-locked (PHL) responses at 30, 37, and 32 dB. J–L: onset (Oi) and chopper (CHOP) responses at 26, 37, and 30 dB. M and N: two types of PSTH (PHL and PLN) obtained from MNTB cells at 42 and 33 dB. Insets show superimposed action potential waveforms (4-ms window) and their averages (gray line). PSTHs are plotted with 0.1-ms binwidth. Abscissa and ordinate scales are identical for A–N. Ordinate shows spikes/bin as a percentage of the total number of spikes. Range shown is 0 to 5 but is extended in some panels to accommodate large peaks.

Figure Lengend Snippet: Strength of phase-locking to tones at CF, for different types of TB fibers, as a function of CF, compared with the auditory nerve (AN). Rmax is graphed against CF. Phase-locking is significant (S.) for the filled symbols. Colors indicate the SPL at which Rmax was obtained, using the ranges indicated. The dashed and solid lines are trendlines for AN and TB data, respectively. The TB trendline excludes MNTB data (MATLAB “lowess,” span 60%; MATLAB). The AN trendline (MATLAB “rlowess” to accommodate larger scatter, span 60%) is for the “near CF” data shown in Fig. 1 of Versteegh et al. (2011). The horizontal line at Rmax = 0.9 marks the “high-sync” criterion. Note the expansive scale of the ordinate, obtained by plotting (1 – Rmax) on a logarithmic and inverted scale (Johnson 1980).

Figure Lengend Snippet: Entrainment to CF tones. A: maximum value of entrainment index (EImax) as a function of CF for the range of 200–1,000 Hz. Square and star symbols represent the EImax for PHL fibers (n = 19) in the TB and for MNTB cells (n = 6), respectively. Solid and dashed lines are trendlines for gerbil and cat (Joris et al. 1994a) TB fibers, respectively (MATLAB “lowess,” span 60%, single data point below 500 Hz excluded). B: maximum firing rate for bushy-type units stimulated at CF. The line in the graph is the unity line, and the color indicates EImax. Symbols identify different classes (same symbols as in Fig. 2). Number of neurons: 11 PLN, 4 PL, 20 PHL, 6 MNTB.

Figure Lengend Snippet: Enhancement in Rmax to tones below CF. A: Rmax values of all bushy-type neurons in the gerbil TB and MNTB for stimuli at CF (open symbols) or below CF (filled symbols), plotted against CF. Different colors indicate the SPL at which Rmax is obtained. The dotted horizontal line indicates the high-sync criterion (Rmax = 0.9). Neurons were sometimes tested at multiple frequencies (see B), so there can be multiple Rmax values per neuron. For neurons that did not generate significant phase-locking to stimuli in the tuning curve tail, no Rmax data point is shown. B: same data as A, with Rmax (color coded) as a function of CF and stimulus frequency.

Figure Lengend Snippet: Entrainment to low-frequency stimuli below CF. A: EImax as a function of stimulation frequency for TB and MNTB neurons. B: maximum firing rate as a function of stimulus frequency, with EImax color coded. The solid line shows equality. A single fiber can contribute multiple data points. The number of fibers in each PSTH category was as follows: 26 PLN, 4 PL, 8 PHL, 4 MNTB.
