Nature:丘脑对功能性皮质连接的控制

2017-05-09 zhangfan MedSci原创

研究揭示了神经科学中的未知领域:丘脑对功能性皮质连接的控制,这个功能与分类信息的传递不相关,表明丘脑具有更为广泛的作用

虽然丘脑和皮层之间的相互作用是认知功能的关键,但丘脑对这种相互作用的确切贡献仍不清楚。研究表明,整个丘脑存在多种连接模式,但是这种多样性的连接是如何实现丘脑与皮质间的信息转化的呢?

研究人员通过对小鼠前额叶皮层注意力功能研究发现,丘脑背维持着这些信息表象但不传递分类信息,特别是丘脑背中部放大了局部前额皮质的连通性,确保特定的神经兴奋的出现与维持。在这一基础上,广泛增强的前额皮质兴奋降低了小鼠的特异性行为表现。
