Erratum: Coupling BCI and cortical stimulation for brain-state-dependent stimulation: methods for spectral estimation in the presence of stimulation after-effects

The article “Coupling BCI and cortical stimulation for brain-state-dependent stimulation: methods for spectral estimation in the presence of stimulation after-effects” (Walter et al., 2012) incorrectly omitted four authors. The list of authors should have been: Armin Walter, Ander Ramos Murguialday, Martin Spüler, Georgios Naros, Maria Teresa Leão, Alireza Gharabaghi, Wolfgang Rosenstiel, Niels Birbaumer, Martin Bogdan.

All further references to this paper should cite the corrected author list as displayed above.

Furthermore, the text of the “Acknowledgments” section needs to be changed to: This work was funded by the European Research Council (ERC) grant 227632 “BCCI—A Bidirectional Cortical Communication Interface” and the Reinhardt-Koselleck Award of the Deutsche Forschungsgemeinschaft (DFG). We thank Alexandros Viziotis for his work with the patients and the two reviewers for helpful comments on the manuscript.
