Changes in Electroencephalogram Approximate Entropy Reflect Auditory Processing and Functional Complexity in Frogs

Asian Herpetological Research 2016年第3期7卷 180-190页

No. 173 Longdu Nan Road Longquan district Chengdu Sichuan China College of Life Science Northwest Normal University.

Brain systems engage in what are generally considered to be among the most complex forms of information processing. In the present study, we investigated the functional complexity of anuran auditory processing using the approximate entropy（Ap En） protocol for electroencephalogram（EEG） recordings from the forebrain and midbrain while male and female music frogs（Babina daunchina） listened to acoustic stimuli whose biological significance varied. The stimuli used were synthesized white noise（reflecting a novel signal）, conspecific male advertisement calls with either high or low sexual attractiveness（reflecting sexual selection） and silence（reflecting a baseline）. The results showed that 1） Ap En evoked by conspecific calls exceeded Ap En evoked by synthesized white noise in the left mesencephalon indicating this structure plays a critical role in processing acoustic signals with biological significance; 2） Ap En in the mesencephalon was significantly higher than for the telencephalon, consistent with the fact that the anuran midbrain contains a large well-organized auditory nucleus（torus semicircularis） while the forebrain does not; 3） for females Ap En in the mesencephalon was significantly different than that of males, suggesting that males and females process biological stimuli related to mate choice differently.

A novel carboxylated lactose/sodium lignosulfonate/polyacrylic acid hydrogel composites with self-reduction capacity was successfully synthesized by self-assembly method. The hydrogel with well-developed porous structure provided abundant anchoring points and reduction capacity for transforming Ag+ into silver nanoparticles. Silver nanoparticles dispersed among the network of hydrogel and the composites exhibited catalytic capacity. The catalytic performance was evaluated via degradation of p-nitrophenol, rhodamine B, methyl orange and methylene blue, which were catalyzed with corresponding reaction rate constants of 0.04338, 0.07499, 0.04891, and 0.00628 s-1, respectively. In addition, the catalyst exhibited stable performance under fixed-bed condition and the corresponding conversion rate still maintained more than 80% after 540 min. Moreover, the catalytic performance still maintained effective in tap water and simulated seawater. The catalytic efficiency still remained 99.7% with no significant decrease after 8 cycles.

全身麻醉是药物诱导下中枢神经系统的抑制状态,是长时间手术操作和有创实验顺利进行的保证。丘脑-皮层环路(特别是丘脑)可能在麻醉-觉醒调控中起着重要作用,但丘脑是否是最重要的调控脑区、调控时是否存在偏侧性尚不清楚。本研究以非洲爪蟾Xenopus laevis为动物模型,在其端脑、间脑、中脑左右两侧分别埋植电极,在鱼安定诱导下进行全身麻醉,连续记录动物在"麻醉前清醒-给药-恢复-麻醉后清醒"过程中的脑电信号,计算各时期的Lempel-Ziv复杂度(LZC)。结果显示:不同状态下的LZC值显著不同,清醒时最大,深度麻醉时最小;给药时长与各脑区LZC值间的显著相关性主要存在于右侧大脑,特别是右侧丘脑。说明LZC可以较好地刻画麻醉-觉醒周期,且右侧丘脑在麻醉-觉醒调控中可能起着重要作用。
