Publisher's Note: Error in Methods

Posted by PLOS_ONE_Group on 05 Aug 2011 at 21:15 GMT


The sentence after the equation in the Methods section should not include the term “r0.” The authors wish to add: "To clarify how the CSF works, note that:
r = RA/(RA+RT); and
r0 = 0.5 in all simulations presented."
