In the article “The Impact of Dopamine on Aggression: An [18F]-FDOPA PET Study in Healthy Males” by Thorben Schlüter, Oliver Winz, Karsten Henkel, Susanne Prinz, Lena Rademacher, Jörn Schmaljohann, Kai Dautzenberg, Paul Cumming, Yoshitaka Kumakura, Steffen Rex, Felix M. Mottaghy, Gerhard Gründer, and Ingo Vernaleken, which appeared on pages 16889–16896 of the October 23, 2013 issue, there was a mistake in the author contributions statement. The phrasing of the sentence “T.S., P.C., G.G., and I.V. wrote the paper.” was not well chosen, because it does not differentiate between initial writing, correcting and critically reviewing the paper. Furthermore, we only stated the contributions to data analysis, but forgot to specify contribution to data interpretation. The Author Contributions footnote should have read 'Author contributions: T.S. and I.V. designed research; T.S., K.H., S.P., L.R., K.D., S.R., F.M.M., and I.V. performed research; O.W., J.S., Y.K., and F.M.M. contributed unpublished analytic tools; T.S., O.W., and L.R. analyzed the data; T.S. interpreted the data; I.V., Y.K., and P.C. supported/supervised data analysis and interpretation; T.S. wrote the paper; P.C., G.G., and I.V. corrected the paper and all authors critically reviewed the paper. These inaccuracies do not affect any of the conclusions or interpretations in our paper.
