In a science project i was performing,i tested the effects the ions potassium 
and calcium chlorides had upon paramecium caudatum.  IN the end the calcium 
chloride remained with no different movement from the control of no ions above 
10 -7 CaCl2.  However, the KCl made the paramecia spin in circles counter 
clockwise.  I was wondering if there is any literature you might recommend or 
if you can answer what the action potential of the cell had to do with its 
movement.  I have not been able to find any literature or lists of what 
actions are taken by cells from the action potential.  In other words i want 
to know what made the cell spin this way?  What responses are or can be given 
from the cell depending on the type or longevity of an action potential?  
Thanks for any and all your help.
