动物的认知过程与运动有关,但一项新的研究表明它们是不同的. 研究人员分离了认知和运动神经动力学,揭示了单独的细胞群体编码每个过程.

科学领域:

神经科学是一个神经科学.
动物行为动物行为
认知科学认知科学

背景情况:

复杂的动物行为涉及认知过程和运动,与神经活动密切相关.
一个关键的问题是认知和运动过程是否共享神经机制,或者是可分离的.

研究的目的:

开发方法来评估认知和运动过程的分离性.
孤立和描述与不同认知和运动组件相关的神经动态.

主要方法:

在小鼠中设计了一项涉及多个认知过程的新型行为任务.
应用了子空间分解技术来隔离认知和运动神经动力学.
分析神经群体活动,以确定编码每个组件的细胞群体.

主要成果:

以前归因于认知的神经动态被发现被运动相关活动污染了.
孤立的认知和运动组件表现出不同的动态轨迹.
大多数分离的神经元群体被确定为编码认知与运动过程.

结论:

复杂行为中的认知和运动过程在很大程度上可以在神经水平上分离.
正确的认知和运动动态的隔离对于理解神经电路功能至关重要.
