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.
