1·The hippocampi from the dim-light group had significantly fewer dendritic spines than those from the dark night group.

在昏暗光条件下的海马比起黑暗环境下的海马减少了重要的树突棘。

2·The morphology of brain nerve cells and the density of dendritic spines were observed after the Nissl's staining and FD staining.

尼氏染色观察大脑神经细胞形态数量，快速高尔基体染色检测海马区域树突棘密度。

3·Dendritic spines are functional protrusions on neuron dendrites and generally act as postsynaptic sites to form integral synapses with axon terminals.

树突棘是神经元树突上的功能性突起结构，通常作为突触后成份与投射来的轴突共同构成完整的突触连接。

4·And what they saw is a steady decrease in the size and number of dendritic spines, the tiny branches of the nerve cell that receive messages from nearby cells.

结果他们看到树突棘的大小和数量稳步下降，而树突棘正是新细胞的微小的分支，可以用来接收临近细胞的信息。

5·And what they saw is a steady decrease in the size and number of dendritic spines, the tiny branches of the nerve cell that receive messages from nearby cells.

他们发现从邻近细胞接受信息的神经细胞的小分支——树突脊的大小和数目发生了逐步的减少。

6·In response to external stimuli, dendritic spines in the cerebral cortex undergo structural remodeling, getting larger in response to repeated activity within the brain.

大脑皮质中的树突棘以重构的方式对外来刺激作出反应。与那些重复性的大脑活动相关的树突棘会变得更粗大。

7·In addition, SP-positive axonal terminals established symmetric axospinous synapses with NT-positive dendritic spines, and axo-axonic synapses with NT-positive axons.

此外，SP阳性轴突末梢还可与NT阳性神经元的树突棘形成对称性轴-棘突触及与NT阳性轴突形成对称性轴-轴突触。

8·Training in a forelimb reaching task leads to rapid (within an hour) formation of postsynaptic dendritic spines on the output pyramidal neurons in the contralateral motor cortex.

这种用前肢踩踏的训练，一个小时内就可以在两侧运动皮层的椎体神经元上形成突触后“树枝状小棘”的结构。

9·Because dendritic spines are the sites of connection between neighbouring nerve cells, the increased number may mean more activity in the fathers' brains than in those of the non-fathers.

由于树突棘是领近神经细胞之间相接触的地方，因此树突棘数量的增多可能意味着父绒猴大脑内的活动比非父绒猴的要多。
