Between-ear sound frequency disparity modulates a brain stem biomarker of binaural hearing

AD Brown, KL Anbuhl, JI Gilmer… - Journal of …, 2019 - journals.physiology.org

High frequency sensitivity to interaural onset time differences in the bat inferior colliculus

Z Haqqee, R Valdizón-Rodríguez, PA Faure - Hearing research, 2021 - Elsevier
Many neurons in the auditory midbrain are tuned to binaural cues. Two prominent binaural
cues are the interaural level difference (ILD) and the interaural time difference (ITD). The ITD …
