NEUROSCIENCE Correction for “The role of long-range connections on the specificity of the macaque interareal cortical network,” by Nikola T. Markov, Maria Ercsey-Ravasz, Camille Lamy, Ana Rita Ribeiro Gomes, Loïc Magrou, Pierre Misery, Pascale Giroud, Pascal Barone, Colette Dehay, Zoltán Toroczkai, Kenneth Knoblauch, David C. Van Essen, and Henry Kennedy, which appeared in issue 13, March 26, 2013, of Proc Natl Acad Sci USA (110:5187–5192; first published March 11, 2013; 10.1073/pnas.1218972110).
The authors note that Fig. 4 appeared incorrectly. The correct figure and its legend appear below.
Fig. 4.
Influence of distance on connectivity. (A) Number of intraregion (Left) and interregion (Right) common-source areas and effects of randomization of connections with preservation of target in-degree. Error bars, 5–95% quantiles after 2 × 104 permutation tests. (B) Density of the edge-complete graphs for intra- and interregions. (C) Histogram showing the number of connected and nonconnected areas at given distance intervals from injected target areas. Black bars, connected source areas; white bars, nonconnected areas. In red, connection density percentage (proportion of connected with respect to unconnected areas) of connectivity with distance. (D) Binary similarity index as a function of distance between target pairs. Abbreviations are the same as in Fig. 2.
Additionally, on page 5190, right column, first full paragraph, lines 21–22, “These values contrast with the interregion graph, in which the density is 50%” should instead appear as “These values contrast with the interregion graph, in which the density is 61%.”
