Question

1. What happens when you double the original extracellular K+ concentration from 3.1 to 6.2 mM?
2. What happens when you go back to the original K+ concentration (3.1) then double the intracellular Na+ concentration?
3. What explains the small effect of changing Na+ concentration compared to changing K+ concentration?
4. What effects does increasing gK (increasing the density of K+ channels) have on action potential timing and waveform?
