Resting Membrane & Action Potential

In order for our neurons to fire off, heart muscle to contract, and kidneys to reabsorb substances, the cells in our body need to establish charge and concentration differences between the inside of the cell and outside the cell (resting membrane potential). In this episode, we explore how our body creates these differences and exploit them to send signals to and from the brain (action potential). We also discuss what can happen to the body if we alter these concentrations and charges.
