In the article “Tyrosine Phosphorylation Sites in ephrinB2 Are Required for Hippocampal Long-Term Potentiation But Not Long-Term Depression” by Farima Bouzioukh, George A. Wilkinson, Giselind Adelmann, Michael Frotscher, Valentin Stein, and Rüdiger Klein, which appeared on pages 11279–11288 of the October 17, 2007 issue, Figure 1 was incorrect.

In the article “Tyrosine Phosphorylation Sites in ephrinB2 Are Required for Hippocampal Long-Term Potentiation But Not Long-Term Depression” by Farima Bouzioukh, George A. Wilkinson, Giselind Adelmann, Michael Frotscher, Valentin Stein, and Rüdiger Klein, which appeared on pages 11279–11288 of the October 17, 2007 issue, Figure 5 was incorrect. The correct Figure 5, printed here, now displays the correct LTP traces induced by TBS. This correction does not change the conclusion of the figure, nor does it change any other conclusion of the study.
