These experiments analyze differences in synaptic development in central auditory pathways between normal hearing (CBA/J) and congenitally deaf (dn/dn) mice, which provide valuable insight into central synaptic plasticity corresponding to human congenital deafness. Immunofluorescent analysis of the developmental expression of the calcium buffering proteins calretinin, calbindin d-28k, and parvalbumin at various postnatal time points was performed to assess the effects of altered neural activity on the level and/or pattern of protein expression within these nuclei. Results indicate that the pattern of calbindin and parvalbumin is unaffected by congenital deafness in dn/dn mice. However, the pattern of calretinin expression in the …
