Methods Rhesus macaques were recruited from an ongoing study at the Wisconsin National
Primate Research Center. Hand dominance was assessed by expert observers based on�…

Recent studies indicate that chimpanzees show a population-level bias for the use of the
right hand for certain tasks. Here we studied the chimpanzees hemispheric asymmetry in the�…

Handedness is thought to originate in the brain, but identifying its structural correlates in the
cortex has yielded surprisingly incoherent results. One idea proclaimed by several authors is�…

Hand preference is a striking example of functional lateralization, with 90% of the population
preferentially using their right hand. However, the search for brain structural correlates of this�…

Handedness is one of the most obvious functional asymmetries, but its relation to an
anatomical asymmetry of the hand representation area in the motor cortex has not been�…

The aim of this study was to characterize, using fMRI, the functional asymmetries of hand
laterality task (HLT) in a sample of 295 participants balanced for handedness. During HLT�…

The development and persistence of laterality is a key feature of human motor behavior, with
the asymmetry of hand use being the most prominent. The idea that asymmetrical functions�…

Structural (cortical surface area, grey matter volume, and cortical thickness) and functional
asymmetry (hemispheric specialization) of brain hemispheres are fundamental�…

Most people are right-handed, preferring the right hand for skilled as well as unskilled
activities, but a notable proportion are mixed-handed, preferring to use the right hand for�…

Ample evidence from functional magnetic resonance imaging studies has demonstrated
functional brain asymmetries in the motor cortex and cerebellum within the task of finger-to�…
