Our latest article is now published as VOR in @elife.bsky.social . We examine contributions of cochlear neural degeneration and pupil-indexed listening effort on speech perception in noise - elifesciences.org/articles/102.... This is a cross-species study and a labor of love from many lab trainees.
Increased listening effort and cochlear neural degeneration underlie speech-in-noise deficits in normal-hearing middle-aged adults
Cochlear neural degeneration in middle-aged adults with normal-hearing thresholds is associated with increased listening effort and behavioral deficits in challenging acoustic environments.

Excited to share our latest work, out now @jneurolang.bsky.social . We find "fuzzier" representations of phonemes in middle-aged adults despite normal hearing, driven in part by peripheral neural coding deficits. In collaboration with @soundbrainlab.bsky.social

Reduced neural distinctiveness of speech representations in the middle-aged brain
Abstract. Speech perception can decline in middle age even when hearing thresholds remain normal, and the underlying neurobiological mechanisms are not well understood. In line with the age-related ne...

Super excited to share the first preprint from my lab, looking at auditory cortical necessity and categorical learning. This one has been cooking for a while and has really set the stage for several other ongoing projects in the lab (stay tuned)! www.biorxiv.org/content/10.1...
