Frequency Following Response: a Window into Auditory Processing and Learning

EasyChair Preprint 15308

Abstract

The frequency-following response (FFR) is a type of auditory electrophysiological signal that has gained attention in audiology, cognitive neuroscience, and related fields. It can help understand subcortical auditory processing and learning. The FFR signal exhibits a phase-locking relationship with the stimulating sound. It primarily originates from the response of the inferior colliculus (IC) in the midbrain, part of the brainstem, and can be measured and recorded using scalp electrodes and specialized equipment. This article introduces the FFR from the perspective of speech signal processing and covers background knowledge on auditory processing and auditory electrophysiology. The cochlear implant (CI) and the related electrically-evoked frequency-following response (eFFR) signal are also introduced, highlighting their challenges and opportunities to offer new insights for readers.
