The original version of this article contains a few typographical errors. These do not affect the results and conclusions that we originally reported. However, to assist readers interested in reproducing our results, we list below several corrections in order to accurately reflect the equations that were used to generate the published figures. Some errors are consequential, and others are less so; we list them all for completeness. Code containing the correct equations is available at ModelDB (http://senselab.med.yale.edu/modeldb).

Equation (2) should appear as follows:

$$ \frac{{d{{[K]}_o}}}{{dt}} = 0.33{I_k} - 2\beta {I_{{pump}}} - {I_{{glia}}} - {I_{{diff}}}. $$

In the appendix, there should be no equation involving g 4, and the equations for g 1, g 2, and g 3 should appear as follows:

$$ {g_1} = 420.0(1.0 - {A_1}{(1.0 - {B_1}\exp ( - {\mu_1}N{a_{{{\text{i}}/{\text{o}}}}}))^{{0.3}}}) $$
$$ {g_2} = \exp ({\sigma_2}(1.0 - {\lambda_2}{{\text{K}}_{{{\text{o/i}}}}})/(1.94 + 1.98\exp ( - {\mu_2}{\text{N}}{{\text{a}}_{{{\text{i}}/{\text{o}}}}}))) $$
$$ {g_3} = (1.0/{(1.0 + \exp ({\sigma_3}(1.0 + {\mu_3}{\text{N}}{{\text{a}}_{{{\text{i/o}}}}} - {\lambda_3}{{\text{K}}_{{{\text{o/i}}}}})))^5})\,(1.0/{(1.0 + \exp ({\sigma_4}(1.0 + {\mu_4}{\text{N}}{{\text{a}}_{{{\text{i/o}}}}} - {\lambda_4}{{\text{K}}_{{{\text{o/i}}}}})))^5}). $$

Finally, two parameters were incorrectly reported. The correct values are σ 2 = 1 and α K  = 0.94.
