A novel stimulus paradigm for simultaneous recording of monaural and binaural frequency following response for identification of binaural interaction component

Abstract

The objective of the study was to investigate whether monaural frequency following response (FFR) of right and left ear and binaural FFR could be obtained in the same recording using a novel stimulus presentation paradigm, for the purpose of identification the BIC. Twenty six young adults participated in the study. The FFR was recorded for 220 Hz pure-tone using a novel stimulus paradigm. The pure-tone was presented sequentially to two ears. Initially, the pure-tone was presented to the right ear, then to both ears, and finally to the left ear. The FFR could be elicited from all participants (all three responses: right ear, left ear, and both ears) in the same recording using the novel stimulus presentation paradigm used in the present study. The novel stimulus presentation paradigm used in the present study could be used for obtaining monaural and binaural FFRs in the same recording for identification of BIC.
