Abstract: This chapter is a general view of the many experimental ways to analyze the sleep–auditory system relationship. Evoked potentials, local-field and far-field human recorded potentials, magneto encephalography, as well as imaging are different points of interest explored in this study. This chapter explores experimental data that will introduce the subject, leading to further analysis of the relationships between audition and sleep. In animal experimentation, a local-field activity can be recorded with electrodes placed into the nuclei or cortex. The evoked potential recorded from the scalp represents a kind of mixture of both near-field and far-field potentials. The evoked potentials can provide information about sensory processing, help to localize a lesion site, or add data about the maturation of or an aged brain. Moreover, two types of response are usually distinguished in humans: sensory and cognitive event–related potentials. The chapter further explains human magneto encephalographic evoked activity recordings in sleep and human auditory brain areas imaging.

Human auditory evoked potentials. I. Evaluation of components.
TL;DR: Fifteen distinct components can be identified in the scalp recorded average evoked potential to an abrupt auditory stimulus, and seem to represent widespread activation of frontal cortex.

TL;DR: In this paper, 15 distinct components can be identified in the scalp recorded average evoked potential to an abrupt auditory stimulus, including early and middle latency components, and longer latency components (P 1, N 1, P 2, N 2 ) over fronto-central scalp regions.

TL;DR: Stages of sleep may be characterized by activation of widespread areas of the brain, including the centrencephalic, paralimbic and unimodal sensory regions, with the specific exclusion of areas which normally participate in the highest order analysis and integration of neural information.
Involuntary attention and distractibility as evaluated with event-related brain potentials.
TL;DR: Recent event-related brain potential studies of involuntary attention and distractibility in response to novelty and change in the acoustic environment show that the mismatch negativity, N1 and P3a ERP components elicited by deviant or novel sounds in an unattended sequence of repetitive stimuli index different processes along the course to involuntary attention switch to distracting stimuli.
Auditory Processing across the Sleep-Wake Cycle: Simultaneous EEG and fMRI Monitoring in Humans
TL;DR: It is found that presentation of auditory stimuli produces bilateral activation in auditory cortex, thalamus, and caudate during both wakefulness and NREM sleep, suggesting that the sleeping brain can process auditory stimuli and detect meaningful events.
