BlackTom AI · Accepted Answer

The question asks about a concept in the auditory system that was developed to overcome the limitations of a prior theory.
Option 1: Place theory. This theory attributes pitch to where along the basilar membrane hair cells are activated, but it does not specifically address overcoming the limitations of frequency theory; it is a distinct approach to pitch perception rather than a modification aimed at solving frequency theory shortcomings.
Option 2: Volley principle. This is the correct choice. The volley principle was proposed to explain pitch perception for frequencies too high for a single neuron to fire at each cycle. By allowing groups of auditory nerve fibers to share the firing load and phase-lock to different parts of the waveform, neurons can encode higher frequencies than individual neurons could alone, thereby addressing the limitations of the pure frequency theory.
Option 3: All-or-none principles. This describes the basic action potential mechanism, where neurons fire at a consistent amplitude regardless of stimulus strength, and does not directly address how pitch is coded across a range of frequencies or how to extend frequency coding beyond single-neuron limits.
Option 4: Signal-detection theory. This framework deals with decision processes under uncertainty and distinguishing signal from noise, not with the specific neural coding of pitch or overcoming frequency theory limitations in the auditory system.
Thus, the volley principle is the concept developed to overcome the limitations of the frequency theory in auditory processing.
