The fEPSP response evoked in one pathway was small, usually 20–30% of the maximu, whereas a large response, usually 80–90% of the maximum, was evoked in the strong pathway. After recording of the baseline fEPSP evoked at 0.033 Hz, LTP of the weak pathway could be associatively induced by paired stimulation of the weak and strong pathways 100 times at 6 sec intervals, with stimulation of the weak pathway preceded 3–10 msec.

在记录以0.033Hz所引发基础的兴奋性突触后电位之后，在弱的路径上可以因配合弱与强的刺激路径而引发出相关性长期增益（每六秒一次共100次，弱的刺激路径在强的刺激路径之前 3-10 ms），然而当在两个路径之间的配合时间差大於10 ms时即无法形成相关性长期增益，此类型长期增益的引发是需要依赖活化NMDA接受器的，因为给予50 mM的D，L-AP5可以阻断相关性长期增益的引发（兴奋性突触后电位为原来的105±6﹪；n=6）。

However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.

Concept of subconsciousness.There are two ways for us to get information: consciousness and subconciousness. Each day we get different extent stimulations tangibly and intangibly, such stimulations waken our awareness and lead to relevant responses. Consciousness is to receive surrounding stimulations mindedly, and subconsciousness is on the contrast way. Subconciousness is the key part of psychological analysis and basis of Sigmund Freud's theory.

何谓潜意识，我们人脑接受信息的方式分为有意识和无意识接收两种方式，我们每天都会受到不同程度有形或无形的刺激，引起我们的注意而产生不同程度的反应，有意识接收是人脑地于周边事物的刺激有知觉地接收信息；而无意识接收是人脑对于周边事物的刺激不知不觉地接收，这就是所谓潜意识，它是精神分析的核心部分，是弗洛伊德的理论的基础。

Moreover, the S1 area was shown to be more easily activated and more intensively innervated by the thalamocortical afferent projections than by the intracortical connections.

The shorter of interruption duration, the more obvious interruption effects, and this support the motion opponency theroy. 3 The different intervals between priming and target were detected. Due to interruption of blank frame, the shorter interruption elicited positive proming effects, which is consistant with integration of temporal and spatial in the human brain. 4 The negative of the same direction is relationship to visual adaption and visual inertia effects.

本系列实验得到以下主要结果与结论：1插入空白图片，将导致特定运动方向的反转，而对二义的运动没有明显影响，反映了空白图片对正常视觉运动的阻断；2阻断时间越短，导致特定运动方向反转的几率越大，即阻断效应越明显，支持运动知觉对立理论；3考察不同间隔的启动——靶刺激，由于空白刺激的插入，启动——靶刺激间隔较短时引起的正性启动效应，与人脑系统对视觉信号的时间与空间整合和视觉惯性是一致的。4同向运动的负性倾斜效应与视觉适应有关。
