Action Potential and Periodic Paralysis Videos
Familial Periodic Paralysis is classified as a voltage-gate ion channelopathy, which means that ion channels do not open and close properly. This results in failure of the muscles' action potential when potassium leaks in and out of the cells inconsistently. Above is an animated video that shows what the process is supposed to be.
Below is a video produced by the Periodic Paralysis Association, which shows and explains the malfunction. Thanks to Dr. Jacob Levitt, Linda Feld, my friend Wade, and all who were involved in the making of this video.
