　　Objective The hippocampus implements its function of initial memory consolidation on the basis of neuronal synchrony.Thus, a possibility is raised with respect to the change in synchronized activity in hippocampal neurons that could serve as a neural circuit mechanism for the consolidation of new memories.

社会环境显著影响雄性蛙类的竞争策略

有效竞争是雄性繁殖成功的决定因素，雄性根据竞争因子(如竞争对手的数量、质量和时空分布)的变化而动态地优化竞争策略。目前尚不清楚这些因素是如何影响雄性竞争的？本研究以仙琴蛙(Babina daunchina)为模型，该蛙能够产生两种不同性吸引力的呜叫(即不同的对手质量)。我们设计具有不同的回放时间间隔(即竞争者数量)和时空随机安排的回放实验，研究竞争因子对竞争策略的影响。

暗纹东方鲀侧线“表面化”神经丘的空间认知功能研究

在鱼类和两栖动物(成体)中存在一类较为原始的机械感受系统—侧线，在鱼类的摄食、集群、导航和通讯等行为中起着重要作用。侧线机械感受器的基本功能单位是神经丘，分为管道神经丘和表面神经丘。近期的研究结果表明，侧线机械感受器中的表面神经丘在帮助鱼体进行定位、定向等空间认知行为中起到了重要作用。暗纹东方鲀的管道神经丘全部表面化，此类表面化的神经丘是否也具有空间感知能力，正是本文所研究的课题。

暗纹东方鲀应激逃避的行为及组织学观察

硬骨鱼及两栖类幼体应激逃避的主要方式是快速逃跑行为,即C-start,而Mauthner 细胞(M细胞)则被认为是指导快速逃跑行为的指令性神经元.本研究发现,当暗纹东方鲀幼鱼和斑马鱼受到骤发的声音刺激(100 Hz,110 dB)时,其反应均为快速逃跑.暗纹东方鲀C-start行为的发生概率为23.9t％,较斑马鱼(73.33％)低；暗纹东方鲀快速逃跑反应的延迟时间为11.95土4.90 ms,而

小清蛋白在褐菖触发声肌中的特性

褐菖鲉(Sebasticus marmoratus)，是一种暖温性底层鱼类，它能够利用发声肌快速收缩使鱼鳔振动而产生声音。发声肌是一对附着于鱼鳔两侧的特殊肌肉，因能够快速收缩而被称为超快肌，其形态特征和物理特性均表现出肌肉快速收缩的适应性。最近有研究表明，小清蛋白(parvalbumin)对于发声肌的快速收缩也可能有重要作用，尤其对于发声脉冲间距较长的发声鱼类。
