Rate of Neural Impulses

Definition

The rate of neural impulses refers to the number of action potentials or electrical signals sent by neurons in a given timeframe. In the context of pitch perception, it is the assumption that the frequency (pitch) of a sound is determined solely by the rate at which auditory neurons fire.

Place Theory:

This theory suggests that different pitches are perceived based on where in the cochlea (inner ear) specific hair cells are stimulated.

Volley Principle:

This principle proposes that groups of neurons take turns firing to achieve higher firing rates than what individual neurons can accomplish alone.

Temporal Coding: It refers to how information about sound frequencies is encoded in patterns and timing of neural firing.
