“…When the EEG is recorded with a nose reference, the fronto-centrally peaking negative waveform often shows a polarity inversion at mastoid sites (Vaughan & Ritter, 1970), suggesting that one of the subcomponents originates from a supratemporal generator structure. Indeed, event-related magnetic field (ERF) counterparts of N1 (the N1m) recorded with MEG closely correspond to fields generated by tangentially oriented dipoles located in the supratemporal auditory cortex (see Elberling, Bak, Kofoed, Lebech, & Saermark, 1980;Hari, Aittoniemi, Järvinen, Katila, & Varpula, 1980).…”

A number studies have shown that the auditory N1 event-related potential (ERP) is attenuated when elicited by self-induced or self-generated sounds. Because N1 is a correlate of auditory feature-and event-detection, it was generally assumed that N1-attenuation reflected the cancellation of auditory re-afference, enabled by the internal forward modeling of the predictable sensory consequences of the given action. Focusing on paradigms utilizing non-speech actions, the present review summarizes recent progress on action-related auditory attenuation. Following a critical analysis of the most widely used, contingent paradigm, two further hypotheses on the possible causes of action-related auditory ERP attenuation are presented. The attention hypothesis suggests that auditory ERP attenuation is brought about by a temporary division of attention between the action and the auditory stimulation. The preactivation hypothesis suggests that the attenuation is caused by the activation of a sensory template during the initiation of the action, which interferes with the incoming stimulation.Although each hypothesis can account for a number of findings, none of them can accommodate the whole spectrum of results. It is suggested that a better understanding of auditory ERP attenuation phenomena could be achieved by systematic investigations of the types of actions, the degree of action-effect contingency, and the temporal characteristics of action-effect contingency representation-buildup and -deactivation.3

“…Thus, N1 is a fronto-centrally component with a peak latency of 100 ms after stimulus onset generated bilaterally mainly in the auditory cortices. Its magnetic equivalent (N1 m/N100 m; Elberling et al 1980;Hari et al 1980) originates deep within the Sylvian fissure in tonotopically organized areas (Yamamoto et al 1988;Cansino et al 1994), but also comprises secondary areas such as Heschl's gyrus, STG and planum temporale providing the major source (Papanicolaou et al 1990;Pantev et al 1995;Jääskeläinen et al 2004;Inui et al 2006).…”

The development of the N1 and N2 components in auditory oddball paradigms: a systematic review with narrative analysis and suggested normative values

Auditory event-related potentials (AERPs) are widely used in diverse fields of today's neuroscience, concerning auditory processing, speech perception, language acquisition, neurodevelopment, attention and cognition in normal aging, gender, developmental, neurologic and psychiatric disorders. However, its transposition to clinical practice has remained minimal. Mainly due to scarce literature on normative data across age, wide spectrum of results, variety of auditory stimuli used and to different neuropsychological meanings of AERPs components between authors. One of the most prominent AERP components studied in last decades was N1, which reflects auditory detection and discrimination. Subsequently, N2 indicates attention allocation and phonological analysis. The simultaneous analysis of N1 and N2 elicited by feasible novelty experimental paradigms, such as auditory oddball, seems an objective method to assess central auditory processing. The aim of this systematic review was to bring forward normative values for auditory oddball N1 and N2 components across age. EBSCO, PubMed, Web of Knowledge and Google Scholar were systematically searched for studies that elicited N1 and/or N2 by auditory oddball paradigm. A total of 2,764 papers were initially identified in the database, of which 19 resulted from hand search and additional references, between 1988 and 2013, last 25 years. A final total of 68 studies met the eligibility criteria with a total of 2,406 participants from control groups for N1 (age range 6.6-85 years; mean 34.42) and 1,507 for N2 (age range 9-85 years; mean 36.13). Polynomial regression analysis revealed that N1 latency decreases with aging at Fz and Cz, N1 amplitude at Cz decreases from childhood to adolescence and stabilizes after 30-40 years and at Fz the decrement finishes by 60 years and highly increases after this age. Regarding N2, latency did not covary with age but amplitude showed a significant decrement for both Cz and Fz. Results suggested reliable normative values for Cz and Fz electrode locations; however, changes in brain development and components topography over age should be considered in clinical practice.

“…Using an oddball procedure, i.e., frequent standard stimuli and infrequent deviant stimuli, the amplitude of the MMN is known to increase with decreasing physical similarity between deviant and standard. However, while this relationship between physical similarity and MMN amplitude has proven valid for sinusoidal tones [Hari et al, 1980;Näätänen et al, 1978;Sams et al, 1985] and complex tones [Näätänen et al, 1993;Vihla et al, 2000], it has been shown that the mismatch negativity in response to deviating speech sounds is dependent on languagespecific long-term memory traces. Non-prototypical speech sounds in a given language, i.e., foreign phonemes, evoke an MMN that is weaker than the one evoked by the prototypical phonemes [Näätänen et al, 1997;Winkler et al, 1999].…”

Abstract:We investigated the early ("preattentive") cortical processing of voice information, using the so-called "mismatch response." This brain potential allows inferences to be made about the sensory short-term store. Most importantly, the mismatch potential also provides information about the organization of long-term memory traces in the auditory system. Such traces have reliably been reported for phonemes. However, it is unclear whether they also exist for human voice information. To explore this issue, 10 healthy subjects were presented with a single word stimulus uttered by voices of different prototypicality (natural, manipulated, synthetic) in a mismatch experiment (stimulus duration 380 msec, onset-to-onset interval 900 msec). The event-related magnetic fields were recorded by a 148-channel whole-head magnetometer and a source current density modeling of the magnetic field data was performed using a minimum-norm estimate. Each deviating voice signal in a series of standard-voice stimuli evoked a mismatch response that was localized in temporal brain regions bilaterally. Increased mismatch related magnetic flux was observed in response to decreased prototypicality of a presented voice signal, but did not correspond to the acoustic similarity of standard voice and deviant voices. We, therefore, conclude that the mismatch activation predominantly reflects the ecological validity of the voice signals. We further demonstrate that the findings cannot be explained by mere acoustic feature processing, but rather point towards a holistic mapping of the incoming voice signal onto long-term representations in the auditory memory.
