Ion acccount in neuron after firing

  1. Sep 14, 2012 #1
    Hi.

    I am learning how neuron transmit current. I am wondering after firing sodium ions are rich and potassium ions are poor in neuron cell. How ion concentrations come back to the original states before firing?

    Thanks for your help in advance.

    Yes. There are many other channels that vary from neuron to neuron, but you have the general picture right.
