德国波鸿鲁尔大学心理学系Martin Stacho取得最新进展。他们发现禽前脑中的皮质样经典回路。该成果发表在2020年9月25日出版的《科学》杂志上。

他们用三维偏振光成像分析了禽前脑的纤维结构,并随后利用描迹技术重建了局部和相关的丘脑回路。他们发现了跨越大脑皮层和感觉背侧心室脊的层状核边界的反复重复的、列状神经元回路。这些回路连接到相邻的列,并通过类似切向层的连接,连接到较高的关联和马达区域。

他们的发现表明,该鸟类的规范回路与其哺乳动物相似,并且可能构成神经元计算的结构基础。

据悉,尽管禽类的大脑似乎缺乏类似于大脑皮层的组织,但鸟类仍具有与哺乳动物相当的认知能力。

Abstract: Although the avian pallium seems to lack an organization akin to that of the cerebral cortex, birds exhibit extraordinary cognitive skills that are comparable to those of mammals. We analyzed the fiber architecture of the avian pallium with three-dimensional polarized light imaging and subsequently reconstructed local and associative pallial circuits with tracing techniques. We discovered an iteratively repeated, column-like neuronal circuitry across the layer-like nuclear boundaries of the hyperpallium and the sensory dorsal ventricular ridge. These circuits are connected to neighboring columns and, via tangential layer-like connections, to higher associative and motor areas. Our findings indicate that this avian canonical circuitry is similar to its mammalian counterpart and might constitute the structural basis of neuronal computation.
