However, the biological significance of each component of such complex sounds is still unclear. Most of the calls of male anuran species are composed of a series of notes and intervals. For example, advertisement calls of the male Emei music frog ( Babina daunchina) frequently contain one to ten or more notes that are separated by intervals of approximately 150 ms. Therefore, Emei music frog is an interesting model to explore the biological significance of each note. By using the optimized paradigm of mismatch negativity (MMN), one standard stimulus (white noise) and 5 deviant stimuli(5 notes from one advertisement call) were played back to frogs and multichannel electroencephalogram recordings were then obtained. The results showed that the MMN amplitudes were greater in the left hemisphere, indicating a left brain advantage for perceiving these deviations. While the MMN amplitude of the first note was significantly larger than that of others. Since the MMN amplitude is thought to reflect not only the difference between the standard and deviant stimuli, but also the brain resources devoted to cognitive processing, it is reasonable to speculate that the first note is the most important unit of vocal communication in frogs. 2017,36(3): 241-248 收稿日期:2016-11-14 DOI:10.11984/j.issn.1000-7083.20160313 分类号:Q955;Q959.5 基金项目:国家自然科学基金项目(31672305;31372217) 作者简介:乐西子,女,硕士,研究方向:动物声音通讯及其神经机理,E-mail:lexz@cib.ac.cn *通讯作者:方光战,E-mail:fanggz@cib.ac.cn 参考文献: 舒华, 张亚旭. 2008. 心理学研究方法:实验设计与数据分析[M]. 北京:人民教育出版社. 薛飞, 方光战, 唐业忠. 2016. 大脑听觉偏侧性的特征与演化[J]. 四川动物, 35(4):626-631.
