Accepting Post-doctoral Scholar Applications

The MUSC Hearing Research Program, in Charleston, S.C., is accepting applications for a Post-doctoral Scholar on age-related changes in hearing and speech recognition. This is a training opportunity to work with an interdisciplinary group of auditory scientists who use neuroimaging, electrophysiology, and psychoacoustic methods. The successful applicant will contribute to a neuroimaging study on speech recognition in older adults. There are also opportunities to interact with members of the MUSC Center for Biomedical Imaging that oversees the research-dedicated 3T Siemens Trio MRI scanner facility, as well as with members of our large neuroscience community. We seek applicants with expertise in audition, language, or attention. The successful candidate will have skills in at least one of the following areas: neuroimaging, programming, and statistics.

Please email Dr. Mark Eckert for additional information (eckert at musc.edu). Applicants should include a CV and a statement of interests. MUSC is located on the coastline, in the heart of historic Charleston.

Cingulo-opercular Activity Provides Word Recognition Benefit

  Recognizing speech in challenging listening conditions often produces increased activity in frontal cortex, particularly in cingulo-opercular regions, but the significance of this activity has been unclear.  This network of frontal cortex is thought to monitor performance and signal when cognitive resources are required to ensure successful performance.  Findings from earlier visuospatial studies indicated that […]

Changes in the Brain that Occur with Hearing Loss

Age-related hearing loss occurs for just about everyone.  We wondered about the potential impact of hearing loss on brain structure because speech recognition can be difficult even after correcting for poor hearing thresholds.  In a sample of 49 older adults, we observed that high frequency hearing loss was associated with lower gray matter volume in […]

Missingness in fMRI Studies: Multiple Imputation

Limited imaging coverage of the brain and susceptibility artifact contributes to missing data in functional imaging studies.  Multiple imputation is one solution for dealing with missing data.  We demonstrate in a recent Neuroimage manuscript the considerable benefit of using multiple imputation in functional imaging studies. There was a 35% increase in the number of voxels […]

Visual System Activity When Listening to Speech: Distracting or Helpful?

Aging is often associated with increased distractibility that may arise from a failure to adequately suppress the processing of irrelevant sensory information. In our recent Cerebral Cortex paper, we show that decreasing word intelligibility was associated with increasing visual cortex activity in younger, middle-aged, and older adults. In addition, age was related visual cortex activity: […]
