... A neuron is like a French Fry: high Na+ outside, high K+ (POTassium/potato) inside!!! During the AP, we will turn our axon INSIDE OUT!!! To fire an action potential, we have to be at resting potential (-70 mV), maintained by closed Na+ and K+ channels If enough NT molecules are picked up by dendrite ...
