The neural encoding of sound is the representation of auditory sensation and perception in the nervous system. [1] The complexities of contemporary neuroscience are continually redefined. Thus what is known of the auditory system has been continually changing.
They may be locked to an external stimulus such as in the visual [12] and auditory system or be generated intrinsically by the neural circuitry. [ 13 ] Whether neurons use rate coding or temporal coding is a topic of intense debate within the neuroscience community, even though there is no clear definition of what these terms mean.
Currently, there is renewed interest in using the FFR to evaluate: the role of neural phase-locking in encoding of complex sounds in normally hearing and hearing impaired subjects, encoding of voice pitch, binaural hearing, and evaluating the characteristics of the neural version of cochlear nonlinearity.

The corresponding train of impulses would contain gaps of 10 ms, 20 ms, 30 ms, 40 ms, etc. Such a group of gaps can only be generated by a 100 Hz tone. The set of gaps for a sound above the maximum neural firing rate would be similar except it would be missing some of the initial gaps, however it would still uniquely correspond to the frequency.
Phase-locking is known as matching amplitude times to a certain phase of another waveform. In the case of auditory neurons, this means firing an action potential at a certain phase of a stimulus sound being delivered. It has been seen that when being played a pure tone, auditory nerve fibers will fire at the same frequency as the tone. [3]

The axons of these cells make up the auditory nerve, encoding the rectified stimulus. The auditory nerve responses select certain frequencies, similar to the basilar membrane. For lower frequencies, the fibers exhibit "phase locking". Neurons in higher auditory pathway centers are tuned to specific stimuli features, such as periodicity, sound ...
Nina Kraus is a professor at Northwestern University, investigating the neural encoding of speech and music and its plasticity where she is the Hugh S. Knowles Chair. [1]Her Auditory Neuroscience Lab, also known as Brainvolts, examines the biological processing of sound throughout the life span, how it is disrupted in clinical populations (language disorders; concussion), and how it reacts to ...
