神经元的

In recent years, rTMS has also been used as a therapeutic tool in a variety of neuropsychiatry disorders such as Parkinson disease and depression that were conceptualized in term of a dysfuction of neuronal circuits and neurons at a cellular and molecular level.

近年来rTMS更是在治疗一系列的神经精神疾患如帕金森病、抑郁等上取得了较好的效果，但其治疗机制尚不明了，而且这些神经精神疾病又被认为是神经环路和神经元在细胞及分子水平上的功能失调，因此探讨rTMS所致的磁刺激对中枢神经系统中神经元基因活性、神经介质或/和调质、结构变化等的调控作用有着重要的意义。

The pathways that regulate tone are similar to those that regulate voluntary and involuntary motor movements and, as a final common pathway, involve the spinal reflex arc.

控制张力的传导通路和那些控制随意或非随意运动的通路是一样的，即脊髓反射弧，这是一个最后的公共通路：控制肌纤维的α运动神经元位于脊髓前角，发出反射弧的传出纤维，源自肌梭的传入冲动经由Ⅰa纤维传向脊髓，这些直接与α运动神经元连接的轴突中的一部分激活主动肌。

Results:(1)NSCs form typical neurospheres under adequate concentration in vitro, which are immunoreactive to Vimentin. Typically and terminally differentiated mature neural cells could not be found without the stimulus of mitogen or only under NSCs self-regulation and self-induction;(2)NSCs derived from hippocampus maintain the character of stem cells much longer with better biological behavior; NSCs passed to the 2-3 passage are the best to graft since they have not differentiated;(3)NSCs cultured in vitro could self-regulate and differentiate into neurospheres and progenitors positively immunoreactive to specific antibodies representing neurons, astrocytes, oligodendrocytes and Schwann cells;(4)There are widespread synaptic contacts between various kinds of descendent clones and cells;(5)Neurospheres could be formed without the stimulus of mitogen when NSCs and OECs are cocultured. Many neurospheres and cells immunoreactive to Vimentin, GFAP, MAP2, 02, p75NGFR, GFAP, S-100, Synaptosis, Vimentin, Tau (Tau is only positive in cocultureof HNSCs+HOECs) could be found;(6)The supernatant fluid triturated from adult rat spinal cord stimulates NSCs to differentiate into neurons, but do not terminally differentiate;(7)Fibroblasts and O4 oligodendrocytes are not supported to grow under this culture medium.Part II: Isolation, culture and identification of rat and human olfactory ensheathing cellsOlfactory ensheathing cells/glials are the most powerful cells to enable the regeneration of axons in the central nervous system.

结果表明：①在适宜的浓度体外培养条件下，NSCs能形成典型的神经干细胞克隆球，Vimentin免疫荧光染色阳性，单靠丝裂原刺激或NSCs自我调节和分化诱导，不会产生典型的终末分化的成熟神经细胞；②海马源性的NSCs维持干细胞特性的时间更长，生物学特性更优；③传至第2～3代的NSCs尚未分化时移植最佳；④体外培养的NSCs能自我调控分化为神经元、星形胶质细胞、O2少突胶质细胞、雪旺氏细胞染色阳性克隆球和前体细胞；⑤各种子代克隆球和细胞存在广泛的突触联系；⑥NSCs与OECs联合培养时，不需丝裂原刺激即能形成克隆球，获得大量Vimentin、GFAP、MAP2、O2、p75NGFR、GFAP、S-100、Synaptosis、Vimentin、Tau(Tau只有人HNSCs+HOECs联合培养时出现阳染)染色阳性的克隆球和细胞；⑦脊髓研磨后的上清液刺激神经干细胞向神经元方向分化，但并不出现终末分化；⑧本研究培养条件不利于成纤维细胞、O4生长。

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

Moutains of evidences from laboratary and clinical data show that gene abnormality is the major etiological factor of over 40% patients affected with epilepsy.There were also 6 epilepsy genes been cloned successfully, and mutations of over 1000 genes maybe related to epilepsy. These abnormal genes influence many aspects from molecular level to the neuronal plasticity, such as the development of brain,neuronic degeneration, remodeling of neural circuits, energy metabolism, ion channel and so on.These factors would at last affect the formation of epilepsy focus, propagations of epileptic potentials, vulnerability of epilepsy cells.

尽管目前尚不能准确有效的诱导神经干细胞特异性定向分化为某种特定的神经元，但随着人们对细胞间信号传递机制认识的不断加深和新的细胞因子、化学信号的不断发现，人类将能够解决从全能干细胞、多能干细胞到神经干细胞、定向神经祖细胞直至特异类型神经细胞的定向分化，完成神经元之间的功能重建，为最终解决中枢神经再生这一难题而开辟道路。

These results indicate that the genome of a post-mitotic, terminally differentiated neuron can re-enter the cell cycle and be reprogrammed to a state of totipotency after nuclear transfer.

这是非同小可的，因为供体神经元只表达一个这样的蛋白，而不是完整的一套蛋白，说明大脑中所表达的嗅觉受体的多样性不是嗅觉神经元DNA中永久排列的结果。
