Abstract

When facing threats, animals not only innately freeze or flee, but can also learn to avoid harmful situations, a behaviour known as 'active avoidance'. A recent study by Hormigo et al. (J. Neurosci., 2019) provides new insights into the neural circuit responsible for this behaviour, placing the pedunculopontine tegmental nucleus (PPT) at its centre.

摘要

当面临威胁时，动物不仅会本能地冻结或逃跑，还可以学会避免有害情况，这种行为被称为“主动回避”。最近 Hormigo 等人的一项研究（《神经科学杂志》，2019 年）提供了关于负责这种行为的神经回路的新见解，将脚桥被盖核（PPT）置于其中心位置。
