个人简介

云南昆明人,长期从事交叉学科的研究工作。1992年赴加拿大、美国留学工作并定居加拿大,2014年回国,主要从事脊髓神经系统运动控制机制的研究,目的是在离子通道、细胞膜特性以及神经网络的基础上,研究哺乳动物行进运动产生、协调和控制的机制;探求运动干预对神经系统适应性重塑的原理;并在此基础上构建基于脊髓神经网络的“类脊髓”智能运动控制系统。在国家自然科学基金面上项目的资助下,主要研究成果包括:(1)在细胞形态和离子通道的水平上解释了运动干预对脑干和脊髓神经系统适应性重塑的机制;(2)在小鼠中脑5-HT神经元和脊髓神经元中发现一种对tetrodotoxin(TTX)、dihydropyridine(DHP) 和 riluzole(RIL)具有强烈阻抗作用的电压门控钠离子通道;(3)通过生理实验和模型仿真预测并验证了五种离子通道NaT、NaP、CaL、K(DR)和K(AHP)在行进运动中的控制作用。这些成果推进了学界同行对细胞兴奋性调节与脊髓运动控制机制的认识和理解。 教育经历 2003 年:美国 University of Washington 医学院生理系,博士后(生物物理学), 导师:Marc Binder 2002 年:加拿大 University of Manitoba 医学院生理系,博士(神经生理学), 导师:Larry Jordan 1995 年:加拿大 University of Manitoba 理学院数学系,硕士(应用数学), 导师:Peter Aitchison 1982 年:云南大学理学院数学系,学士(计算数学) 工作经历 2014 至今:华东师范大学紫江特聘教授 2003-2013:加拿大 University of Manitoba 医学院脊髓研究中心(SCRC)资深合作研究员

研究领域

我研究的方向是脊髓运动控制与干预(spinal motor control and exercise intervention)。脊椎动物的行进运动(locomotion)由位于中脑的运动中枢(Mesencephalic Locomotor Region:MLR)引导和控制,由分布于脊髓系统中的神经网络群执行和操作,这个网络群称为中枢模式发生器(Central Pattern Generator:CPG)。CPG在行进运动中扮演着时钟调控、节律发生和运动控制的作用,它由多层次的神经细胞群组成,沿着脊髓腹侧的胸段和腰段分布,具有特殊的神经细胞膜特性,与不同兴奋和抑制类型的神经突触相互连接,受多种神经递质的调控。由于神经网络的复杂性和技术手段的有限性,尽管我们对CPG的结构有了深刻的认识和了解,但对于脊髓神经网络能够引导肢体产生运动这种内源能力依然知之甚少。我研究的目的就是在神经元和离子通道的水平上认识这种能力,探求行进运动产生的原理;揭示运动干预对运动神经系统适应性重塑的机制;并将这些机制与原理应用于人工智能运动控制系统的研发中,构建类脑智能运动控制系统的核心结构。鉴此,我的研究包括:运动干预、智能仿生、通道调节和细胞识别等四个方面的内容: 运动干预:研究长期运动训练(chronic exercise)如何在离子通道和细胞形态的水平上修饰和调控脑干-脊髓神经元的细胞膜特性,重塑神经系统的适应性,使运动系统更加有效地适环境的变化。 智能仿生(类脊髓研究):究神经元和神经网络的计算特性,分析神经元基于离子通道的信息编码与解码原理,通过生物信息仿真技术,运用交叉学科的研究方法,探索类脊髓研究的生理与技术手段,建立从神经元到神经网络、从脑干到脊髓的大型神经网络模型,集成化设计多足智能机器人的运动控制系统。 通道调节:研究脑干-脊髓神经元中离子通道的生物物理学特性,探索作为一种机制离子通道是如何调节神经元的兴奋性进而参与行进运动的控制和协调。 细胞识别:识别和特征化描述参与引导、控制、执行和协调行进运动的脑干-脊髓神经元,分析它们在行进运动中的功能和作用,研究它们的细胞膜特性如何接受神经递质的调节进而对运动控制发挥作用。 电生理和计算神经学是我从事研究的主要方法,这是将运动神经生理学与生物物理学、数学模型以及计算机仿真模拟技术相互结合的交叉学科的研究方法,也是生物信息学在脊髓神经系统研究中的拓展和应用。其特点是将膜片钳技术与神经元数学模型相结合,以神经系统建模仿真为平台,运用神经生理与信息仿生的方法研究脊髓运动控制的机制和原理。我研究的最终目的是认识行进运动产生、控制和协调的机制;解释运动干预对脊髓神经系统适应性重塑的规律。研究的结果可以为青少年和普通民众的运动锻炼、脊髓损伤病人的康复治疗、以及智能机器人的应用研发提供生物医学方面的依据和参考。
