NEUROSCIENCE Correction for “Caloric restriction improves memory in elderly humans,” by A. V. Witte, M. Fobker, R. Gellner, S. Knecht, and A. Flöel, which appeared in issue 4, January 27, 2009, of Proc Natl Acad Sci USA (106:1255–1260; first published January 26, 2009; 10.1073/pnas.0808587106).
The authors note that the following two sentences should have been included on page 1257, left column, first full paragraph, after the sentence ending in the fifth line: “Note that one subject had to be excluded from the correlation analysis for insulin and one subject had to be excluded for hs-CRP due to a measurement error in insulin or hs-CRP, respectively. Therefore, analyses were conducted with 9 of initially 10 subjects defined by weight loss of >2 kg.” This error does not affect the conclusions of the article.
