Although Peromyscus species are well-represented in genetic, developmental, and behavioral studies, relatively few studies have investigated auditory sensitivity in this genus. Given the potential utility of Peromyscus for investigations of age-related changes to auditory function, we recorded auditory brainstem responses (ABRs) in two Peromyscus species, P. californicus, and P. leucopus, across the lifespan. We compared hearing sensitivity and ABR wave metrics measured in these species with measurements from Mus musculus (CBA/CaJ strain) to assess age-related effects on hearing across species. Recordings in young animals showed that all species had similar heariJournal of the Association for Research in Otolaryngology : JAROPhysiological Evidence for Delayed Age-related Hearing Loss in Two Long-lived Rodent Species (Peromyscus leucopus and P. californicus).PMC9613845R01 DC016641R01 DC017620T32 DC000027T32 DC000023Weinberg MMVicencio-Jimenez SScreven LACapshaw GBurke KLauer AMfalsePhysiological Evidence for Delayed Age-related Hearing Loss in Two Long-lived Rodent Species (Peromyscus leucopus and P. californicus).Deer mice (genus Peromyscus) are an emerging model for aging studies due to their longevity relative to rodents of similar size.
