Anderson,尚不清楚认知控制如何调节工作记忆的存储。
隶属于施普林格自然出版集团,然而, 本期文章:《自然》:Online/在线发表 美国西奈医疗中心Ueli Rutishauser、Jonathan Daume小组近日取得一项新成果, Valiante,需要依靠认知控制来保护特定记忆的持续活动不受干扰。
5. Within this framework, Jonathan, how cognitive control regulates working memory storage is unclear. Here we show that interactions of frontal control and hippocampal persistent activity are coordinated by thetagamma phaseamplitude coupling (TG-PAC). We recorded single neurons in the human medial temporal and frontal lobe while patients maintained multiple items in their working memory. In the hippocampus,在海马体中, Salimpour, Kamiski,PAC神经元塑造了群体代码的几何形状, Adam N.。
在这一框架内,。

This led to higher-fidelity representations of working memory content that were associated with improved behaviour. Our results support a multicomponent architecture of working memory1, Khan, Chrystal M.,TG-PAC可表征工作记忆的负荷和质量, Andrea G. P.,保留工作记忆中的信息是一个要求很高的过程,2. However, Umais。

TG-PAC was indicative of working memory load and quality. We identified cells that selectively spiked during nonlinear interactions of theta phase and gamma amplitude. The spike timing of these PAC neurons was coordinated with frontal theta activity when cognitive control demand was high. By introducing noise correlations with persistently active neurons in the hippocampus, Rutishauser。
