Gap-induced inhibition of the post-auricular muscle response in humans and guinea pigs (2019)
Journal Article
Wilson, C. A., Berger, J. I., de Boer, J., Sereda, M., Palmer, A. R., Hall, D. A., & Wallace, M. N. (2019). Gap-induced inhibition of the post-auricular muscle response in humans and guinea pigs. Hearing Research, 374, 13-23. doi:10.1016/j.heares.2019.01.009

A common method for measuring changes in temporal processing sensitivity in both humans and animals makes use of GaP-induced Inhibition of the Acoustic Startle (GPIAS). It is also the basis of a common method for detecting tinnitus in rodents. Howeve... Read More

Auditory attention causes gain enhancement and frequency sharpening at successive stages of cortical processing: evidence from human EEG (2018)
Journal Article
sharpening at successive stages of cortical processing: evidence from human EEG. Journal of Cognitive Neuroscience, 30(6), doi:10.1162/jocn_a_01245. ISSN 0898-929X

Previous findings have suggested that auditory attention causes not only enhancement in neural processing gain, but also sharpening in neural frequency tuning in human auditory cortex. The current study was aimed to reexamine these findings, and inve... Read More

Effect of contralateral medial olivocochlear feedback on perceptual estimates of cochlear gain and compression (2016)
Journal Article
Fletcher, M. D., Krumbholz, K., & de Boer, J. (2016). Effect of contralateral medial olivocochlear feedback on perceptual estimates of cochlear gain and compression. Journal of the Association for Research in Otolaryngology, 17(6), doi:10.1007/s10162-016-0574-8. ISSN 1525-3961

The active cochlear mechanism amplifies responses to low-intensity sounds, compresses the range of input sound intensities to a smaller output range, and increases cochlear frequency selectivity. The gain of the active mechanism can be modulated by t... Read More
