对大鼠、仓鼠、豚鼠、浣熊、猫、狗等动物的鼓索神经在不同化学刺激条件下的电反应进行了定量比较。仓鼠和豚鼠对0.5[图像]蔗糖的反应很好；猫只有轻微反应。20 mM奎宁-盐酸对兔的反应最大；0.01[图像]盐酸对仓鼠的反应最大；而狗在这两种性质上的反应都很低。与Kc1相比，啮齿类动物对氯化钠的反应更好；然而，食肉动物的反应正好相反。NH4Cl在这两个订单中都引起了很大的反应。在水冲洗过程中观察到的自发活动在兔子身上丰富，在猫身上中等，在豚鼠、仓鼠和狗身上只有轻微的自发活动。在低浓度的氯化钠作用下，该酶活性受到抑制。
Electrical responses recorded from the chorda tympani nerve as different chemical stimuli were applied to the tongue were quantitatively compared in rats, hamsters, guinea pigs, racoons, cats and dogs. The hamster and guinea pig responded well to 0.5 [image] sucrose; the cat only slightly. The greatest response in rabbits was elicited by 20 mM quinine-HCl; 0.01 [image] HCL elicited a large response in hamsters; whereas, the dog gave a low response in both of these qualities. The rodents responded well to NaCl compared to KC1 at all concn.; however, the reverse was true in carnivores. A large response was initiated in both orders by NH4Cl. The spontaneous activity observed during a water rinse was abundant in the rabbit, moderate in the cat, and only slight in the guinea pig, hamster, and dog. This activity was suppressed in the rabbit with low concentration of NaCl.
