[Addendum]

In the article "The Seizure Prediction Problem in Epilepsy: Cellular Nonlinear Networks" published in the fourth issue of 2012 of this Magazine, the numbering of some references has been mixed up. Specifically, reference [21] has been included as reference [70] and references [22] to [69] are off by one. The following list of references should be used in lieu of those in the published article.
