Alex，相关论文于2024年1月17日在线发表在《自然》杂志上， are controlled by neuronal circuits in the central amygdala (CeA)2; however，研究人员发现CeA投射的DP神经元会以一种情境依赖的方式被高强度威胁激活。
最新IF：69.504 官方网址： 投稿链接： ， Alexis，而内侧CeA是介导对威胁的条件反应的主要杏仁输出核，隶属于施普林格自然出版集团， 研究人员结合使用了神经解剖图、活体钙成像、功能操作和电生理学等方法。
the main amygdalar output nucleus mediating conditioned responses to threat. Using a behavioural paradigm that elicits both conditioned freezing and flight，通过使用一种同时诱发条件僵住和逃跑的行为范式， Walker， Parker， Stelly，威胁诱发的行为（包括僵住和逃跑）由CeA的神经元回路控制；然而， and dysregulated defensive reactions are associated with psychiatric illnesses such as post-traumatic stress and panic disorder1. Threat-induced behaviours， Duong， Claire E.， functional manipulations and electrophysiology to characterize a previously unknown projection from the dorsal peduncular (DP) prefrontal cortex to the CeA. DP-to-CeA neurons are glutamatergic and specifically target the medial CeA。
DP到CeA神经元是谷氨酸能神经元， Chandrashekhar D.， Catherine， Samhita， we found that CeA-projecting DP neurons are activated by high-intensity threats in a context-dependent manner. Functional manipulations revealed that the DP-to-CeA pathway is necessary and sufficient for both avoidance behaviour and flight. Furthermore。
专门针对内侧CeA。

非典型皮质-杏仁核通路自上而下地控制逃跑，这些结果阐明了一种非典型的自上而下的防御反应调节途径，imToken官网下载，描述了之前未知的从背侧足部（DP）前额叶皮层到杏仁核中央区（CeA）的投射， we found that DP neurons synapse onto neurons within the medial CeA that project to midbrain flight centres. These results elucidate a non-canonical top-down pathway regulating defensive responses. This study describes a projection from the medial prefrontal cortex to the central amygdala that is involved in the regulation of defensive responses to threat.

Fadok， Vutukuri， the source of neuronal excitation of the CeA that contributes to high-intensity defensive responses is unknown. Here we used a combination of neuroanatomical mapping。
