Brain Aging and Speech Perception in Noise
Brain aging and speech perception in noise: effects of background noise and talker variability
Task fMRI and structural and diffusion MRI of healthy younger and older adults, collected to study how age, background noise and talker variability affect syllable discrimination. Scans are not public; group surface maps and task stimuli are open under CC BY-NC 4.0.
Overview
This entry covers the MRI cohort of a two-experiment study from the Speech Neuroscience Laboratory at the CERVO Brain Research Center and Université Laval in Quebec City. Healthy adults across the adult lifespan performed an auditory syllable discrimination task in which syllables were played in quiet or in pink noise and spoken by one or two talkers. The study asked why speech perception in noise declines with age and whether that decline maps onto focal auditory changes or onto a wider set of brain regions. The scans are not public. A Borealis deposit under CC BY-NC 4.0 holds the stimuli, the task code and group-level surface maps.
Composition
Experiment 1 tested speech perception, hearing and auditory attention in adults aged 19 to 87 years. The paper abstract reports 88 participants and the deposit description 83. Experiment 2 scanned a subset of 32 of them. A companion paper on diffusion MRI reports 14 young and 15 elderly adults. Per-group ages and sex counts for the MRI subset are not given in the public sources opened for this entry.
Acquisition
Experiment 2 combined task fMRI with the shorter in-scanner version of the discrimination task (96 experimental and 48 filler trials) and structural MRI analysed for cortical thickness with FreeSurfer surfaces. High angular resolution diffusion imaging of the same experiment was analysed with tractography of the arcuate and middle longitudinal fasciculi. Scanner vendor, field strength and sequence parameters could not be confirmed from an openly reachable source and are left out.
Annotations
There are no image labels. The shared group products are a FreeSurfer average brain of the 32 participants, cortical thickness group differences and BOLD contrasts for noise, talker and their interaction with age group, as corrected and uncorrected AFNI/SUMA surface datasets.
Known limitations
- Individual MRI and behavioural data are not shared; participants did not consent to individual data sharing.
- The deposit only suits replication of group maps or reuse of the stimuli, not image-level model training.
- The two public sources disagree on the Experiment 1 sample size (88 vs 83).
- Small MRI sample from a single site.

The Borealis deposit (CC BY-NC 4.0) holds the auditory stimuli, the Presentation experiment files, a FreeSurfer group average surface of the 32 MRI participants and group-level cortical thickness and BOLD maps in AFNI/SUMA surface formats. The deposit states that individual behavioural and MRI data cannot be shared because participants did not consent to individual data sharing.
