In collaboration with colleagues, he contributed to “Expression studies of osteoglycin/mimecan (OGN) in the cochlea and auditory brainstem” (2008, Hearing Research), exploring gene expression relevant to cochlear maintenance and listed by the National Institute of Health.
Dr. Darrow’s research also addresses efferent balancing mechanisms, as seen in “Cochlear efferent feedback balances interaural sensitivity” (2006, Nature Neuroscience), which elucidates how neural feedback maintains auditory symmetry. Methodological advancements are evident in “Direct visualization of the murine dorsal cochlear nucleus for optogenetic stimulation of the auditory pathway” (2015, Journal of Visualized Experiments), detailing techniques for precise neural targeting.
Further strengthening his credentials, publications like “Usherin is required for maintenance of retinal photoreceptors and normal development of cochlear hair cells” (2007, Human Molecular Genetics) link auditory and visual sensory systems, while “Methylthioadenosine phosphorylase (MTAP) in hearing: gene disruption by chromosomal rearrangement in a hearing impaired individual and model organism analysis” (2007, American Journal of Medical Genetics Part A) investigates genetic factors in hearing impairment. His work on cortical mapping, “Robustness of cortical topography across fields, laminae, anesthetic states, and neurophysiological signal types” (2012, Journal of Neuroscience), demonstrates stability in auditory cortical organization. Finally, “Optogenetic stimulation of the cochlear nucleus using channelrhodopsin-2 evokes activity in the central auditory pathways” (2015, Brain Research) pioneers light-based neural activation in auditory circuits.
A key example from his applied audiology efforts is his article “Dementia and the Role of the Hearing Healthcare Provider,” published in The Hearing Review in January 2023, which outlines the responsibilities of audiologists in identifying and mitigating dementia risks linked to untreated hearing loss. This piece draws on epidemiological data to emphasize proactive interventions. Additional contributions appear in professional outlets, including discussions on cognitive outcomes from treating hearing impairments.
