The<unk>  <unk> , also referred to as<unk><unk>  potential (FFP) or envelope<unk><unk>  (EFR), is an evoked potential generated by periodic or nearly-periodic auditory stimuli. Part of the auditory brainstem<unk>  (ABR), the<unk>  reflects sustained neural activity integrated over a population of neural elements: "the brainstem<unk> ...can be divided into transient and sustained portions, namely the onset<unk>  and the<unk>  <unk> ". It is often phase-locked to the individual cycles of the stimulus waveform and/or the envelope of the periodic stimuli. It has not been well studied with respect to its clinical utility, although it can be used as part of a test battery for helping to diagnose auditory neuropathy. This may be in conjunction with, or as a replacement for, otoacoustic emissions.
