脊椎动物大脑结构和功能的季节性变化已经在许多物种中被描述，特别是在季节性繁殖者中。然而，目前还不清楚性二态性是否会在特定的大脑区域的繁殖季节之间发生变化。采用听觉事件相关电位（ERP）研究了峨眉乐蛙听觉敏感性的性别差异和季节变化。采用oddball范式设计进行了声学回放实验，其中两种同种叫声类型被用作偏离刺激，合成白色噪声作为标准刺激。分析了非生殖状态和生殖状态下两性端脑和中脑的ERP成分。结果表明，听觉敏感性受到生殖状态的调节，这意味着听觉感知涉及季节可塑性。此外，N1 ERP组件的振幅（平均振幅发生在刺激开始后30-130毫秒的时间间隔内）是较高的女性端脑和较高的男性中脑，无论生殖状态和声刺激类型。这些结果表明，听觉ERP反应的特定脑区表现出性二态性的外源性刺激的情况下，在两个繁殖状态的音乐蛙。
Seasonal changes in the structure and function of the vertebrate brain have been described in many species, particularly in seasonal breeders. However, it remains unclear whether sexual dimorphism varies between breeding seasons for specific brain regions. Auditory event-related potential (ERP) changes were evaluated in the Emei music frog (Babina daunchina) to assess sexual dimorphism and seasonal variations in auditory sensitivity. An acoustic playback experiment using an oddball paradigm design was conducted, in which two conspecific call types were used as deviant stimuli with synthesized white noise as standard stimulus. ERP components were analyzed for the telencephalon and mesencephalon of both sexes in the non-reproductive and reproductive states. Results show that auditory sensitivity is modulated by reproductive status, implying that seasonal plasticity is involved in auditory perception. Moreover, the amplitude of the N1 ERP component (mean amplitudes during the interval occurring 30–130 ms after stimulus onset) is higher in females for the telencephalon and higher in males for the mesencephalon, regardless of reproductive status and acoustic stimulus type. These results show that auditory ERP responses for specific brain regions exhibit sexual dimorphism in the absence of exogenous sexual stimulation during both the two reproductive states in the music frog.
