Recent studies indicate that chimpanzees also show a population-level right-handed bias, although it is less strong than in humans. METHODOLOGY/PRINCIPAL FINDINGS: We used in vivo diffusion-weighted and T1-weighted magnetic resonance imaging (MRI) to study the relationship between the corticospinal tract (CST) and handedness in 36 adult female chimpanzees. Chimpanzees exhibited a hemispheric bias in fractional anisotropy (FA, left&amp;gt;right) and mean diffusivity (MD, right&amp;gt;left) of the CST, and the left CST was centered more posteriorly than the right. Handedness correlated with central sulcus depth, but not with FA or MD. CONCLUSIONS/SIGNIFICANCE: These anatomical results are qualitatively similar to those reported in humans, despite the differences in handedness. The existence of a left&amp;gt;right FA, right&amp;gt;left MD bias in the corticospinal tract that does not correlate with handedness, a result also reported in some human studies, suggests that at least some of the structural asymmetries of the corticospinal system are not exclusively related to laterality of hand preference.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">20877630 </style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;&lt;span role=&quot;menubar&quot;&gt;PLoS One.&lt;/span&gt;&amp;nbsp;2010 Sep 21;5(9):e12886. doi: 10.1371/journal.pone.0012886.&lt;/p&gt;</style></notes><auth-address><style face="normal" font="default" size="100%">Biomedical Imaging Technology Center, Emory University, Atlanta, Georgia, USA.</style></auth-address></record></records></xml>
