ERP and behavioral changes during the wake/sleep transition

TL;DR: The findings suggest that, although the processes underlying P300 are less likely to be engaged, processing of stimulus deviance and task relevance continues in sleepiness and sleep, and is reflected by variance in N350 and related activity.

Abstract: Event-related potentials (ERPs) following infrequent and frequent stimuli were studied as subjects moved from wakefulness to sleep. Subjects were instructed to respond to the infrequent "target" stimuli (attend condition) or to ignore the stimuli (ignore condition). Parietal P300, prominent following target ERPs in wakefulness under the attend condition, disappeared in association with reduced behavioral responsiveness and emergence of a central negativity (N350). The N350 and preceding and following positivities (P220 and P450) became the dominant feature of both target and nontarget ERPs under both attend and ignore conditions. The P220-N350-P450 complex was larger and peak latencies were shorter under the attend condition. Peak amplitudes tended to be larger following targets, especially under the attend condition. The findings suggest that, although the processes underlying P300 are less likely to be engaged, processing of stimulus deviance and task relevance continues in sleepiness and sleep, and is reflected by variance in N350 and related activity.

The mismatch negativity during natural sleep: Intensity deviants.
TL;DR: Auditory event-related potentials (ERPs) were recorded from 7 subjects who slept for a single night in the laboratory using an 'oddball' sequence of brief tone pips, differing in intensity, which elicited a broad fronto-central negativity with two discernable peaks.
Mismatch negativity during objective and subjective sleepiness.

TL;DR: The results show that the MMN is attenuated by a decrease in alertness even before an actual sleep state is reached.
Event‐related potentials during forced awakening: a tool for the study of acute sleep inertia
TL;DR: The forced awakening test provided a robust and relatively rapid tool to evaluate both sleep propensity and sleep inertia within a single recording session, and proved to be much more discriminative than waking ERPs alone to demonstrate specific abnormalities in patients complaining of excessive daytime sleepiness.
Event-related potential measures of the inhibition of information processing: II. The sleep onset period.
TL;DR: The infrequent change of an otherwise rapidly presented homogenous train of stimuli is associated with another long-lasting negativity, the mismatch negativity (MMN), which decreases in amplitude during the sleep onset period, reaching baseline level during definitive sleep.
Auditory event-related potentials to deviant stimuli during drowsiness and stage 2 sleep
TL;DR: Data indicate that differential processing of auditory inputs is maintained during drowsiness and stage 2 sleep, but do not support the notion that MMN or P3 activity comparable to the waking state occurs to oddball stimuli during this stage.

TL;DR: During the First International EEG Congress, London in 1947, it was recommended that Dr. Herbert H. Jasper study methods to standardize the placement of electrodes used in EEG (Jasper 1958).

A new method for off-line removal of ocular artifact.
TL;DR: EMCP permits retention of all trials in an ERP experiment, irrespective of ocular artifact, and has the advantage that separate correction factors are computed for blinks and movements and that these factors are based on data from the experimental session itself rather than from a separate calibration session.

Is the P300 component a manifestation of context updating
TL;DR: The amplitude of the P300 component is controlled multiplicatively by the subjective probability and task relevance of eliciting events, whereas its latency depends on the duration of stimulus evaluation as mentioned in this paper.

TL;DR: It is concluded that at least six different cerebral processes can contribute to the Nl wave of the human auditory evoked potential, and that they often last much longer than the true N1 components that they overlap.

TL;DR: Two distinct late-positive components of the scalp-recorded auditory evoked potential were identified which differed in their latency, scalp topography and psychological correlates.
