Single-unit responses to SAM tones in AI of unanesthetized monkey (Malone et al. 2007). For each single-unit, a best modulation frequency (BMF) was calculated either based on overall firing rate increase (B) or on a temporal measure (C). Both measures indicate a peak at ~5-10 Hz, with the majority of BMFs found in the range ~4-32 Hz. The joint distribution (A, 361 AI neurons total) shows that the two measures are roughly, but not perfectly, correlated.
