In the article “Mechanisms Leading to Rhythm Cessation in the Respiratory PreBötzinger Complex Due to Piecewise Cumulative Neuronal Deletions” by Hanbing Song, John A. Hayes, Nikolas C. Vann, M. Drew LaMar, and Christopher A. Del Negro, which appeared on pages e0031-15.2015 of the July/August 2015 issue, the authors made an error in the Materials and Methods section when reporting the model parameters. The value of TNa-P should be 1000 ms instead of 15 ms. The correct value was used throughout the study so that the conclusions of this article are not affected. This correction would assist readers to better understand our study.
