Mildly pinching the tail of the rat results in a set of consummatory behaviors including eating, chewing and licking. This phenomenon has been characterized as one which is not causally dependent on induction of pain. In the present study we report that pinching the scruff of the neck, the ears, or the rear paw of rats also results in consummatory behaviors similar to those observed during tail pinch. We suggest that stress-induced eating caused by pressure applied to various regions of the rat involves the perception of noxious stimuli (nociception).
轻轻捏大鼠的尾巴会引发一系列包括进食、咀嚼和舔舐在内的完成行为。这种现象的特征是其并非因果性地依赖于疼痛诱导。在本研究中，我们报告称，捏大鼠的颈部、耳朵或后爪也会导致类似于捏尾巴时观察到的完成行为。我们认为，对大鼠身体各部位施加压力所引起的应激性进食涉及对有害刺激（伤害感受）的感知。
