The reversal potential and the property that the current was rapidly blocked by external 1 mm bacl2 made sure that the current we recorded was carried by k + 电流的反转电位( 60mw及其被胞外baci 。迅速抑制的特征表明记录到的电流为k ”电流。
In a biological membrane, the reversal potential (also known as the Nernst potential) of an ion is the membrane potential at which there is no net (overall) flow of that particular ion from one side of the membrane to the other. In the case of post-synaptic neurons, the reversal potential is the membrane potential at which a given neurotransmitter causes no net current flow of ions through that neurotransmitter receptor's ion channel.
