Correction for Fox et al., Spontaneous neuronal activity distinguishes human dorsal and ventral attention systems

neuroscience. For the article “Spontaneous neuronal activity distinguishes human dorsal and ventral attention systems,” by Michael D. Fox, Maurizio Corbetta, Abraham Z. Snyder, Justin L. Vincent, and Marcus E. Raichle, which appeared in issue 26, June 27, 2006, of Proc. Natl. Acad. Sci. USA (103, 10046–10051; first published June 20, 2006; 10.1073/pnas.0604187103), the authors would like to note the following: “The population-level random effects maps (e.g., Fig. 1) are not Z score maps as indicated, but t value maps over 10 subjects (9 degrees of freedom). As such, the applied threshold (t = 3) represents a significance of ‘P < 0.015, non-corrected’ as opposed to the indicated ‘P < 0.01, corrected for multiple comparisons.’ Because these maps are replicated across three data sets (controlling for false positives) and are independent of the statistics used to test the hypotheses (see Figs. 2 and 3), this correction does not alter the conclusions of the article.”
