Stochastic undersampling steepens auditory threshold/duration functions: implications for understanding auditory deafferentation and aging

It has long been known that some listeners experience hearing difficulties out of proportion with their audiometric losses. Notably, some older adults as well as auditory neuropathy patients have temporal-processing and speech-in-noise intelligibility deficits not accountable for by elevated audiometric thresholds. The study of these hearing deficits has been revitalized by recent studies that ...

Auditory Temporal Processing and Aging: Implications for Speech Understanding of Older People

Current estimates of the prevalence of age-related hearing loss among those over 65 years in the U.S. converge on an overall prevalence rate of approximately 50%, suggesting that there are currently 20 million senior citizens with significant hearing loss (Agrawal et al., 2008; Cruickshanks et al., 1998; Moscicki et al., 1985). Because the post-World War II baby generation (generally known as t...

Understanding the auditory-fMRI

The neuroanatomy of the auditory system is well established (Brodal, 1998). Input to the brainstem comes through VIII cranial nerve. First station is cochlear nucleus. From the cochlear nucleus, auditory information is split in two. Some nerve fibers going to the ventral cochlear nucleus synapse on their target cells with giant, hand-like terminals. This serves as timing of the signal. The vent...
