Erratum: Keitel et al., “Stimulus-Driven Brain Rhythms within the Alpha Band: The Attentional-Modulation Conundrum”

In the article “Stimulus-Driven Brain Rhythms within the Alpha Band: The Attentional-Modulation Conundrum”, by Christian Keitel, Anne Keitel, Christopher S.Y. Benwell, Christoph Daube, Gregor Thut, and Joachim Gross, which appeared on pages 3119–3129 of the April 17, 2019 issue, due to a production error, a duplication of Equation 1 appeared instead of Equation 2. The correct Equation 2 appears below, and the online version has been corrected.
