可塑性

Furthermore, abnormal morphology, shrinkage and reduced density of dendritic spines and defects in LTP were observed in brains of the patients suffering from mental retardation and neurodegenerative diseases; many mutant genes found from these patients encode component proteins of signal transduction for neuronal plasticity. These studies on synaptic plasticity would certainly promote making the effective prevention and treatment procedures for mental and neurodegenerative diseases.

On the basis of theories of high-level visual processing subsystems and by following Sternberg's element-adding study pattern, serial studies were made to investigate the plasticity of visual cognitive ability in space. The results show that different degrees of plasticity and stability do exist in the cognition processing of visual space. Moreover, plasticity and flexibility in judgments of appearance swirl and quantitative spatial relationship and in command of visual characteristics are found greater in these studies than those obtained by means of appearance scanning, movement inference and judgment of categorical space relation.

视觉空间能力认知可塑性系列研究以高水平视觉加工子系统理论为基础，以斯滕伯格的加因素法为研究范式，通过对视觉空间任务的练习效应与年龄效应的检验表明，视觉空间认知加工中存在着的不同程度的可塑性与稳定性，结果显示出表象旋转、数量空间关系判断和视觉特征提取任务明显要比表象扫描、运动推断以及类别空间关系判断表现出较强的可塑性和易变性特点。

Objective: To explore the changes on expression of NT-4 and IGF-I in spared dorsal root ganglia (DRG, L6) in operated/acupuncture side and unoperated /unacupuncture side, spinal lamina II (L3, L5, L6) and Clarke' nucleus (L3) of normal adult, partial dorsal rhizotomy and acupuncture spared DRG cats so as to know the relation between NT-4, IGF-I and the plasticity of spinal cord as well as acupuncture promoting spinal cord plasticity.

目的：探讨NT-4和IGF-I在正常猫、部分去背根猫及针刺部分去背根猫的L_6背根节和脊髓Ⅱ板层(L_3、L_5、L_6)与背核(L_3)表达的时空变化，以了解该两因子在脊髓可塑性及针刺促进脊髓可塑性中的关系。

Seasonal changes are one of the most dramatic examples of plasticity found between breeding and nonbreeding seasons.

鸣禽在成年之后表现出广泛的鸣唱行为可塑性变化，其中与季节相关的可塑性变化最为突出。

The results showed that the architecture of seedlings was modified plastically in response to different light conditions.

通过对不同光照条件下桂花幼苗的冠形、分枝率、叶片在树冠中的空间分布等特征进行研究，结果表明桂花幼苗构型发生了明显的可塑性适应：其树冠对光照条件的变化有显著的可塑性响应。

These findings indicate that there is plasticity in response to micro\|habitat heterogeneity along the continuous moisture content gradients of sand dunes at the ramet population and clonal fragment levels.

结果表明，准噶尔无叶豆对沙丘坡面水分条件连续变化的异质性小生境存在分株种群及克隆片段两个等级的可塑性响应，并通过可塑性变化适应了沙丘坡面水分条件的分异。

Additionally, species with larger plasticity in biomass allocation and relative growth rate also showed higher seedling survival rate.7 All these suggested that higher light availability in grazed disturbed meadow community favor seedling recruitment for these familiar forbs component species, but bottom shade in fertilized meadow community restrain seedling recruitment for these species.

在变化的微生境下，具有较小生长可塑性的物种具有相对较大的幼苗存活率；而生物量、株高可塑性和平均可塑性较高的物种具有相对较大的幼苗越冬存活率；具有较大的生物量分配和相对生长率可塑性的物种幼苗具有相对较大的存活率。7放牧干扰下的高光照微生境有利于这些草甸常见组分种实生幼苗的更新补充，而施肥后草甸群落冠层底部的低光生境不利于这些物种的更新补充。
