New research shows that, like humans, capuchin monkeys may have certain differences in brain structure that are related to sex and ‘handedness’. Kimberley Phillips (Hiram College, Hiram, OH) and colleagues measured the size of the corpus callosum, the main white matter structure connecting the two cerebral hemispheres, in 14 capuchin monkeys. Nine of the monkeys were also given a test used to determine handedness (PLoS One 2, e792; 2007).
