Firing Rate

定义 Definition

firing rate:指“发放频率/放电频率/射速”,常见于两类语境:

  1. 神经科学:神经元在单位时间内产生动作电位(spikes)的次数(常用单位:Hz,次/秒)。
  2. 武器/工程:武器或装置在单位时间内发射的次数(射速)。

发音 Pronunciation

/far ret/

例句 Examples

The neuron's firing rate increased when the light turned on.
灯亮起时,这个神经元的放电频率增加了。

Researchers compared firing rates across brain regions to understand attention.
研究人员比较了不同脑区的放电频率,以理解注意力机制。

词源 Etymology

firing 来自动词 fire(“开火;点燃;引发”),加 -ing 构成名词化形式,表示“发射/点火/发放”的动作或过程;rate 表示“速率、比率”。合起来 firing rate 就是“发射/发放的速率”。在神经科学里,“firing”引申为神经元“发放(动作电位)”。
