摘要

在哺乳动物中,内嗅-海马体网络神经元的活动是由动物的位置和空间运动来调节的。在这个分布式回路的多个阶段,不同的神经元群可以代表丰富的与导航相关的变量,比如动物的位置、运动的速度和方向,或者边界和物体的存在。协同工作,空间调谐神经元产生了对空间的内部表征,这是一幅认知地图,支持动物导航世界的能力,以及从经验中编码和巩固记忆的能力。在发育过程中,大脑获得创造空间内部表征能力的机制才刚刚开始被阐明。在这篇综述中,我们研究了最近开始研究哺乳动物大脑中空间表征基础的电路、放电模式和计算的个体发生。

How Do You Build a Cognitive Map? The Development of Circuits and Computations for the Representation of Space in the Brain.

In mammals, the activity of neurons in the entorhinal-hippocampal network is modulated by the animal's position and its movement through space. At multiple stages of this distributed circuit, distinct populations of neurons can represent a rich repertoire of navigation-related variables like the animal's location, the speed and direction of its movements, or the presence of borders and objects. Working together, spatially tuned neurons give rise to an internal representation of space, a cognitive map that supports an animal's ability to navigate the world and to encode and consolidate memories from experience. The mechanisms by which, during development, the brain acquires the ability to create an internal representation of space are just beginning to be elucidated. In this review, we examine recent work that has begun to investigate the ontogeny of circuitry, firing patterns, and computations underpinning the representation of space in the mammalian brain.

期刊介绍: The Annual Review of Neuroscience is a well-established and comprehensive journal in the field of neuroscience, with a rich history and a commitment to open access and scholarly communication. The journal has been in publication since 1978, providing a long-standing source of authoritative reviews in neuroscience. The Annual Review of Neuroscience encompasses a wide range of topics within neuroscience, including but not limited to: Molecular and cellular neuroscience, Neurogenetics, Developmental neuroscience, Neural plasticity and repair, Systems neuroscience, Cognitive neuroscience, Behavioral neuroscience, Neurobiology of disease. Occasionally, the journal also features reviews on the history of neuroscience and ethical considerations within the field.
