This divalent cation is released from presynaptic vesicles into the synaptic cleft upon neuronal activity and acts as a modulator of many ligand-gated ion channels.

锌离子随着神经元的活动从突触前膜的囊泡中释放到突触间隙，对突触内受体进行调控。

Because the binding of the neurotransmitter (ligand) to the receptor activates these ion channels, they are called ligand-gated channels to distinguish them from voltage-gated channels.

因为神经递质和受体结合（配位）启动了这些离子通道， 所以他们被称为配位门通道，以区别于电压门通道。
