The vestibular apparatus of the decerebrate rat was stimulated by tilting the head dorsally or ventrally, with or without an associated stimulation of neck afferents i.e. either the head alone, or the head and body together, was tilted. The effect of such conditions, upon short latency reflexes elicited in antagonistic jaw and hyoid muscles, was examined. Reflexes in the different jaw and hyoid muscles were affected differently when the head was tilted, whether or not neck movement was permitted. Variations in the pattern of response in different animals were explicable on the basis of the known variable recovery of neck reflexes opposing the influence of the vestibular afferents. Head position can therefore be an important but complex factor which may enhance or depress reflex activity differentially in the different masticatory muscles, at least in the experimental situation.
通过使大鼠头部背侧或腹侧倾斜来刺激去大脑大鼠的前庭器官，同时伴有或不伴有颈部传入神经的相关刺激，即单独倾斜头部，或同时倾斜头部和身体。研究了这种情况下对拮抗的颌骨和舌骨肌肉中引发的短潜伏期反射的影响。当头部倾斜时，无论是否允许颈部运动，不同颌骨和舌骨肌肉中的反射受到的影响都不同。不同动物反应模式的变化可以根据已知的与前庭传入神经影响相反的颈部反射的可变恢复来解释。因此，头部位置可能是一个重要但复杂的因素，至少在实验情况下，它可能会在不同的咀嚼肌中差异地增强或抑制反射活动。
