AP PSYCHOLOGY

Detailed explanation-1: -Volley theory states that groups of neurons of the auditory system respond to a sound by firing action potentials slightly out of phase with one another so that when combined, a greater frequency of sound can be encoded and sent to the brain to be analyzed.

Detailed explanation-2: -For example, if a sound with a frequency of 20, 000 Hz enters the ear, many different neuron will take turns processing this sound until all 20, 000 Hz are able to be processed.

Detailed explanation-3: -Because an individual neuron can only fire at a maximum of 1, 000 times per seconds, but neural cells with alternate firing can achieve a combination of 4, 000 firings per second. This, called the volley principle, explains why we can hear low-pitched sounds.

Detailed explanation-4: -The Volley Principle is an information encoding scheme used in human hearing. Nerve cells transmit information by generating brief electrical pulses called action potentials. Sound is encoded by producing an action potential for each cycle of the vibration, eg.
