What is the meaning of calcium conductance in ion channels. I encountered this in the following text:
It was established that the µ and δ opioid receptors open potassium channels, which results in reduction of calcium conductance (Simon, 2005).
Also why should opening a potassium channel reduce calcium conductance. How are they related ?
