The frequency of spontaneous UP/DOWN transitions could be entrained to a regular interval by repetitive sound stimuli with intervals ranging 3-12 sec, in which each sound stimulus effectively induced a UP-to-DOWN transition.

外界声音刺激（白噪声，0.1-35 KHz）能调制神经元自发的高电、低电位期的传递节律：当声音刺激落在高电位期时，每一次声音刺激都会使细胞膜电位由高电位期向低电位期转变，并当声音刺激间隔在3-12秒范围内时，自发的高、低电位期的转变节律就同步于声音刺激的重复率，即跟随效应。
