In the snail, the pH 6.7-6.8 decreased the neuron membrane potential in 10% of cases and increased it in 30%. The hyperpolarisation was equal to 9(5 mV, the effect being abolished by addition of 5-10 M strophantidine. The findings suggest that low pH activates sodium conduction, the hyperpolarisation being caused by activation of the K+/Na(+)-pump.
在蜗牛中，pH值6.7 - 6.8在10%的情况下会降低神经元膜电位，而在30%的情况下会使其升高。超极化幅度等于9（5毫伏，加入5 - 10 M毒毛花苷K后该效应消失。这些发现表明，低pH值会激活钠传导，超极化是由K⁺/Na⁺泵的激活引起的。
