Animals use auditory cues generated by defensive responses of others to detect impending danger. Here we identify a neural circuit in rats involved in the detection of one such auditory cue, the cessation of movement-evoked sound resulting from freezing. This circuit comprises the dorsal subnucleus of the medial geniculate body (MGD) and downstream areas, the ventral area of the auditory cortex (VA), and the lateral amygdala (LA). This study suggests a role for the auditory offset pathway in processing a natural sound cue of threat.

丘脑,皮层和杏仁核参与处理危险的自然声音提示。

动物利用其他人的防御反应产生的听觉线索来发现即将发生的危险。在这里,我们确定了大鼠中的一种神经回路,该神经回路参与了这样一种听觉线索的检测,即由冰冻引起的运动诱发声音的停止。该回路包括内侧膝状体(MGD)的背侧亚核和下游区域,听觉皮层的腹侧区域(VA)和外侧杏仁核(LA)。这项研究表明听觉偏移通路在处理威胁的自然声音提示中的作用。
