Continuous stimulation at frequencies equal to or greater than 5 hertz for 20 to 30 minutes results in a two- to fivefold increase in the amplitudes of excitatory postsynaptic potential recorded from certain stretcher and opener muscles of decapod crustaceans. This long-term facilitation appears to result from an accumulation of sodium ions within the nerve terminals. It persists for at least 1 hour after stimulation has stopped.
以等于或大于5赫兹的频率持续刺激20至30分钟，会使从十足目甲壳动物的某些伸展肌和开肌记录到的兴奋性突触后电位的幅度增加两到五倍。这种长期易化作用似乎是由神经末梢内钠离子的积累导致的。在刺激停止后，它至少持续1小时。
