Auditory evoked field

Auditory evoked field or AEF is an induced neural activity (by an auditory stimulus) that is recorded via magnetoencephalography (MEG), which is an equivalent of Auditory evoked potential (AEP) recorded by electroencephalography. 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 cortical level while focusing on the role of the auditory pathway. The common applications of AEF are prenatal and neonatal hearing screening, cortical pitch perception, language comprehension, and attention.
