High spontaneous-rate nerve fibers have low thresholds and vice versa

Evidence

We observe a strong relationship between the firing rate of a neuron and the stimulus level. Using Figure 2–8, we also note that the threshold and SR of a neural fiber are related. The threshold of a neuron is defined as the lowest sound level that leads to a measureable increase in the driven spike rate. High spontaneous rate fibers have low thresholds, whereas low spontaneous fibers have high thresholds. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 235
