This page is a redirect. The following categories are used to track and monitor this redirect:

From a merge: This is a redirect from a page that was merged into another page. This redirect was kept in order to preserve the edit history of this page after its content was merged into the content of the target page. Please do not remove the tag that generates this text (unless the need to recreate content on this page has been demonstrated) or delete this page.
- For redirects with substantive page histories that did not result from page merges use {{R with history}} instead.

From a subtopic: This is a redirect from a subtopic of the target article or section.
- If the redirected subtopic could potentially have its own article in the future, then also tag the redirect with {{R with possibilities}} and {{R printworthy}}.

To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}} instead.

When appropriate, protection levels are automatically sensed, described and categorized.

-'''Auditory evoked field''' or '''AEF''' is an induced neural activity (by an auditory stimulus) that is recorded via [[magnetoencephalogram|magnetoencephalography]] (MEG), which is an equivalent of [[Auditory evoked potential]] (AEP) recorded by [[EEG|electroencephalography]]<ref>Jacobson GP. Magnetoencephalographic studies of auditory system function. J Clin Neurophysiol. 1994 May;11(3):343-64.</ref>. The advantage of ''AEF'' over ''AEP'' is the powerful spatial resolution provided by [[magnetic field]] recording, which ''AEP'' lacks. Thus, researchers using ''AEF'' often deals with the global responses of the whole brain at the [[cortex|cortical]] level while focusing on the role of the auditory pathway. The common applications of AEF are ''neonatal screening'', ''cortical pitch perception'', ''language comprehension'', and ''attention''.
-==Sources and Types of Responses==
-The main source of the Auditory evoked field is the [[auditory cortex]] and the association cortices. The earliest cortical components of AEF is equivalent to the ''middle latency response'' of the EEG evoked potential, called the '''middle latency auditory evoked field''' or '''MLAEF''', which occurs at 30 to 50 ms after the stimulus onset<ref>Kuriki S, Nogai T, Hirata Y. Cortical sources of middle latency responses of auditory evoked magnetic field. Hearing Research 92 (1995) 47-51.</ref>.
-At 100 ms after stimulus onset occurs the most prominant response in the late latency range, the '''N100m''', which corresponds to the [[N100|N1]] peak of [[Auditory long latency response|ALR]]<ref>Virtanen J, Ahveninen J, Ilmoniemi RJ, Näätänen R, Pekkonen E. Replicability of MEG and EEG measures of the auditory N1/N1m-response. Electroencephalogr Clin Neurophysiol. 1998 Apr;108(3):291-8.</ref>.
