| 摘 要： | 既往研究发现听觉感知包括对声音信号的觉察、感觉、注意和知觉等多个认知过程,但依然不清楚大脑如何对不同类型的复杂声音信号(如同种鸣声和其他声音)进行解码和处理,以及在感知不同类型声音信号时大脑活动的动态特征.本研究记录了在随机播放白噪声和洞内鸣叫声音刺激时仙琴蛙Nidirana daunchina的左右端脑、间脑和中脑的...

| Abstract: | Auditory perception includes multiple cognitive processes such as detection,sensation,attention and consciousness of acoustic signals.However,it is still unclear that how the brain decodes and processes different types of complex sounds(e.g.,conspecific calls and other sounds)and what the dynamic characteristics of brain activities for perceiving different types of acoustic signals are.We recorded the electroencephalogram(EEG)of the music frog(Nidirana daunchina)in both sides of the telencephalon,diencephalon,and mesencephalon under random playbacks of white noise and conspecific advertisement calls.We calculated the absolute power spectrum for each EEG band in order to compare the attributes of brain activities for perceiving different types of sounds.The results showed that sound stimulation increased the activity of each EEG band,and the intensity of brain activity was modulated by the biological significance of sound stimulation,indicating that all EEG bands involve in auditory perception in N.daunchina. |
