In order for the brain and peripheral nervous system to work properly, neurons must communicate effectively with one another. This communication is accomplished at specialized structures called synapses. The vast majority of synaptic contacts are made on neuronal dendrites. Synaptic complexes found in dendrites are complex transduction machines created by a partnership between pre- and postsynaptic cells. The dendritic membrane outside of the synaptic specialization is also a highly specialized, dynamic structure that is richly invested with voltage-dependent ion channels, G-protein coupled receptors, signaling enzymes, translational and protein processing machinery. Fundamental insights into the roles of dendrites in health and disease are emerging from our ability to visualize these microscopic regions dynamically in living tissue. NU is rapidly becoming a world center in the study of dendrites and synaptic function. The NU group was nucleated by the recruitment of Drs. Nelson Spruston and Catherine Wooley, internationally recognized leaders in the study of neuronal dendrites. In 2001, Dr. James Surmeier was recruited to the Chair of the Physiology Department at FSM. Having a well-established reputation for the study of neuromodulatory mechanisms that are critical to dendritic function in neurons, he put in motion a strategic plan to dramatically expand the group of neuroscientists working in this area at NU. This decision was predicated upon 1) existing strengths in this area, 2) the recognition that this was an emerging area of neuroscience and 3) the conviction that a wide array of major neurological disorders - Parkinson's disease, Alzheimer's disease, neuropsychiatric disorders, and drug abuse - were likely to be primarily disorders of dendrites and synaptic function. With the recruitment of twelve new faculty members into this area in the last three years, this group has achieved a critical mass. Even though the recruitment has focused heavily on junior investigators (because this is an emerging area of neuroscience), the group is already very well funded by NIH, receiving roughly $12M in 2004-05, of which $XM is derived from NINDS. This figure is sure to grow as many of the young recruits with 2P expertise (e.g., P. Osten, J. Waters, G. Shepherd) are submitting their first grants to NINDS this year.

为了使大脑和周围神经系统正常工作，神经元必须有效地交流 彼此联系。这种交流是在称为突触的特殊结构中完成的。绝大多数 突触接触是在神经元树突上进行的。在树突中发现的突触复合体是复杂的 由突触前和突触后细胞之间的伙伴关系创建的转导机器。树突膜 在突触特化之外，还有一个高度特化的动态结构， 电压依赖性离子通道、G蛋白偶联受体、信号传导酶、翻译和蛋白质加工 机械.树突在健康和疾病中的作用的基本见解正在从我们的 能够动态地可视化活组织中的这些微观区域。 NU正在迅速成为树突和突触功能研究的世界中心。NU集团是 由纳尔逊斯普鲁斯顿博士和凯瑟琳伍利，国际公认的领导人， 在神经树突的研究中。2001年，James Surmeier博士被聘为生理学系主任。 在FSM的部门。在神经调节机制的研究方面享有盛誉， 对于神经元中的树突功能至关重要，他启动了一项战略计划， 神经科学家在这个领域工作这一决定是基于1）这一领域的现有优势， 2)认识到这是神经科学的一个新兴领域，3）相信广泛的 主要的神经系统疾病--帕金森氏病、阿尔茨海默氏病、神经精神疾病和药物滥用--可能主要是树突和突触功能障碍。招募了12名 在过去的三年里，新的教员进入这个领域，这个群体已经达到了临界质量。即使 招聘主要集中在初级研究人员（因为这是神经科学的一个新兴领域）， 该小组已经得到了美国国立卫生研究院的充分资助，在2004- 2005年收到了大约1200万美元，其中XM美元来自 NINDS。这一数字肯定会随着拥有2 P专业知识的年轻新兵（例如，P.
