Our latest preprint from the lab is out now - www.biorxiv.org/content/10.1... We show that reduced neural coding of temporal fine structure cues predicts increased listening effort during multi-talker speech perception. Feedback welcome.

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.

Aravind Parthasarathy@aravindhearing.bsky.social · 2y agoExcited to share our newest article , now in Scientific Reports @natureportfolio.bsky.social . Here we look at interactions between neural coding of temporal cues and pupil-indexed listening effort, and their combined effects on speech in noise intelligibility. - www.nature.com/articles/s41...
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 direct.mit.edu/nol/article/...
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...

✨Thrilled to kick off 2025 by sharing our new paper, led by @abmongol.bsky.social, on how the auditory system’s encoding of precise timing cues (temporal fine structure) could benefit our day-to-day listening: www.pnas.org/eprint/IFCPF...
Individual differences elucidate the perceptual benefits associated with robust temporal fine-structure processing | PNAS
The auditory system is unique among sensory systems in its ability to phase lock to and precisely follow very fast cycle-by-cycle fluctuations in t...

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...
Latest from our lab-we developed and validated a new EEG-based measure to assess neural representation of temporal envelope cues from the auditory pathway - the dynamic amplitude modulated envelope following response (dAM EFRs) - rdcu.be/d0mTl @PittCSD @PittSHRS
