神经元在受电刺激时诱发AP（action potential），依次由局部电位、锋电位和后电位三部分组成。锋电位是AP的特征部分，通常说的AP主要指这一部分。锋电位包括从局部电位基础上迅速去极化的上升分支，即去极化相，并超过零电位而发生膜电位的翻转，即反极化相或超射，随后膜电位迅速复极化形成下降分支，即复极化相。 锋电位（spike potential）在刺激后几乎立即出现，潜伏期不超过0.06毫秒。其幅度为静息电位与超射值之和，并服从全或无定律和非递减性传导。
The spontaneous activity is composed by multiple signals with different frequency, and the spikes firing are high-frequency signals.

爆发活动信号高能量所在频段比随机单发锋电位活动和连续发放锋电位活动信号的要低。
The frequency bands of high-energy for burst activities are lower than those of random single spike firing and continuous single spike firing.
