通过自主研发的设备,老鼠大脑里的神经结构、神经元之间如何连结,有无疾病,一测便知。武汉光电国家实验室近日宣布,生物医学光子研究中心骆清铭教授带领的科研组首次绘制出了全球最高分辨率的小鼠全脑图谱,对研究人类脑疾病有重大意义。文章发表在Science和 Neuroimaging等期刊上。

此前,已经有多个国家的科研人员绘制出脑图谱,但都不具备足够的成像分辨率,并且图谱只停留在局部切片,无法在全脑范围观察到连接所有神经细胞的轴突和树突。

为了解决这个难题,骆清铭带领的团队将传统的切片扫描技术应用在一种全新的自动模式中,把制备好的鼠脑安装在自主研发的显微光学切片层析成像仪器上切片和成像。

然后,通过仪器的图像连续采集装置,对鼠脑样本做全自动连续242小时的数据采集,最终获得15380层像素分辨率为0.3×0.3微米的冠状断面图像,空间分辨精度达到亚微米级,不足一根头发丝粗细的六十分之一。

同时,科研组利用高定位精度的三维移动平台,及在切片中采用对先采取到的信息进行验证分析的方法,对图像准确定位和预处理,实现了小鼠全脑结构成像,获得了一套来自同一只老鼠的全脑组织切片图谱。

该成果已经在世界著名的《科学》杂志2010年发表,接下来将进入产业化阶段。“揭示大脑中准确的神经连结关系非常重要,因为很多复杂的大脑疾病可能是由大脑内回路连结出现的问题所导致。高分辨率的全脑图谱能进一步推动人类对抑郁症、帕金森等疾病的了解。”骆清铭说。

Nature:与任务相关的感觉输入信息的选择性整合

灵长类动物前额皮质的神经元代表着感觉刺激的多个方面,能产生依赖于任务的、随时间变化的反应。 这些复杂反应何以代表它们在不同情况下对行为所提供输入信息的相关方面、或何以对行为做出贡献仍不清楚。【原文下载】 Valerio Mante等人在这项研究中发现,当猴子执行一项依赖于场景的感觉运动任务时,与任务相关的信号和与任务无关的信号在前额皮质的同一单元内混在一起,但却容易在发生在神经类群层面上的一个

Nature:皮层的连接方式与感觉

Neurology:说外语有助于延缓痴呆

一项研究发现,说两种语言有助于延缓痴呆症的发生。而且,只要说外语就可以达到这种效果,不在乎说几种外语,也不在乎是否能读写外语。 这项研究发表在最新一期《神经学》杂志上。法新社11月6日说,这是科学家首次发现文盲说外语也能延缓痴呆症。 研究人员对648名被诊断出患有不同程度痴呆症的印度人进行语言能力调查。他们的平均年龄为66岁,分别患有阿兹海默氏症、血管性痴呆等痴呆相关疾病。结果发现,那些会说两
