Responses to head tilt were recorded from eighth nerve axons in barbiturate anesthetized cats. The maximally excitatory head tilt (polarization vector), a zero-force discharge rate, and tilt sensitivity were measured for each cell. In one population of afferents, the maximum discharge frequency was obtained by aligning the saccular plane with gravity. The response properties of these saccular afferents were compared with a second population arising from the utriculus. Both the resting discharge rate and the response sensitivity were lower for saccular than utricular afferents in the cat. The average resting discharge was about 20% lower and the sensitivity about 15% higher in the cat than in the squirrel monkey.
在巴比妥类麻醉的猫中，记录了来自第八神经轴突对头部倾斜的反应。测量了每个细胞的最大兴奋性头部倾斜（极化矢量）、零力放电率和倾斜敏感度。在一组传入神经中，通过将球囊平面与重力对齐来获得最大放电频率。将这些球囊传入神经的反应特性与来自椭圆囊的另一组传入神经进行了比较。猫的球囊传入神经的静息放电率和反应敏感度均低于椭圆囊传入神经。与松鼠猴相比，猫的平均静息放电约低20%，敏感度约高15%。
