We have previously described (Exp. Neurol., 97: 315-326, 1987) that clamping of the neck elicits a profound immobility with flexion of limbs and ventroflexion of head and neck ('carrying posture'). We also observed that when a clamped rat pup is carried by the experimenter's hand, such carrying posture was potentiated. In the present paper we observed that in adult rats vestibular stimulation by circular acceleration potentiates the duration of immobility reflex by clamping and intensifies the limb flexion. In rat pups from 10 to 20 days, vestibular stimulation potentiated only the carrying posture but not the duration of the immobility reflex by clamping.
我们之前已经描述过(《实验神经病学》,97: 315 - 326, 1987),夹住颈部会引发一种深度不动状态,伴有四肢屈曲以及头部和颈部腹屈(“抱姿”)。我们还观察到,当实验者用手抱起被夹住的幼鼠时,这种抱姿会增强。在本文中,我们观察到,在成年大鼠中,通过圆周加速进行前庭刺激会增强夹住引起的不动反射的持续时间,并加剧四肢屈曲。在10至20日龄的幼鼠中,前庭刺激仅增强了抱姿,但并未增强夹住引起的不动反射的持续时间。
