Correction

I n volume 1, number 6, 2011 issue of Brain Connectivity, the authors of the article, “Altered Structural Brain Connectivity in Healthy Carriers of the Autism Risk Gene, CNTNAP2” by Emily L. Dennis et al. on pages 447–459, discovered several important errors after the article was published.

The results of the paper are all correct, and they remain the same; specifically, the Results section of the paper correctly states that people who carry two risk alleles for autism have lower eccentricity in their structural brain networks. However there are two points in the paper where this result is stated in the incorrect direction.

The sentence in the Abstract, “In graph theory analyses, subjects homozygous for the risk allele (CC) had lower characteristic path length, greater small-worldness and global efficiency in whole brain analyses, and greater eccentricity…” should read, “In graph theory analyses, subjects homozygous for the risk allele (CC) had lower characteristic path length, greater small-worldness and global efficiency in whole brain analyses, and lower eccentricity…”

Additionally, the sentence in the Discussion, “Further analyses at the nodal level revealed that the homozygous at-risk participants had greater eccentricity…” should read, “Further analyses at the nodal level revealed that the homozygous at-risk participants had lower eccentricity…”

The authors regret these errors, and wish to thank Christian Clemm of the Psychiatry Neuroimaging Laboratory at Brigham Women's Hospital, Boston, for noticing the discrepancy in these two sentences, and for bringing this to their attention on September 11, 2012.
