Figure 3From: Age-related synaptic loss of the medial olivocochlear efferent innervationABR thresholds for 2- and 12-month-old YFP-12 mice under the C57BL/6J genetic background. ABR thresholds (Mean ± S.D) for 2-month-old mice (n = 7; grey line) were significantly lower than the thresholds (Mean ± S.D) from 12-month-old mice (n = 7; black line).Back to article page
