来自昆虫机械感觉毛发神经元的外部直接耦合记录显示了响应毛发变形的神经冲动和分级慢电位。这些慢电位或受体电位呈负向，随刺激强度直接变化，并且在返回基线时不会出现过冲。脉冲具有初始正相位，其大小直接随受体电位的幅度而变化。受体电位与脉冲发生器电位相关，因为在产生脉冲之前它必须达到某个临界水平，并且脉冲的频率直接随受体电位的幅度变化。每次脉冲后受体电位不会返回到基线。在某些受体中，头发的静态变形将保持受体电位。似乎受体电位和脉冲大小的变化都是由受体位点处细胞膜电导的变化引起的，并且受体电位起源于未被传播的脉冲侵入的位点。
External direct coupled recordings from the neurons of the mechanosensory hairs of insects show nerve impulses and graded slow potentials in response to deformation of the hair. These slow potentials or receptor potentials are negative going, vary directly with the magnitude of the stimulus, and show no overshoot when returning to baseline. The impulses have an initial positive phase which varies in size directly with the amplitude of the receptor potential. The receptor potential is related to the generator potential for the impulse in that it must attain some critical level before impulses are produced, and the frequency of impulses varies directly with amplitude of the receptor potential. The receptor potential does not return to the baseline after each impulse. In some receptors static deformation of the hair will maintain the receptor potential. It appears likely that both the receptor potential and the variation in size of the impulses are caused by a change in conductance of the cell membrane at the receptor site, and that the receptor potential originates at a site which is not invaded by the propagated impulses.
