Across time and place, right hand preference has been the norm, but what is the precise
prevalence of left-and right-handedness? Frequency of left-handedness has shaped and …

Directional hemispheric dominance has been established for numerous cognitive functions
in the human brain. Strong population biases with some functions favoring the left and …

Lateralization is a fundamental principle of nervous system organization but its molecular
determinants are mostly unknown. In humans, asymmetric gene expression in the fetal …

Dominance of the left hemisphere for many aspects of speech production and perception is
one of the best known examples of functional hemispheric asymmetries in the human brain …

Neuroendocrine theories of brain development hold testosterone as the predominant factor
mediating sex-specific cortical growth and the ensuing lateralization of hemispheric function …

Genetic and environmental factors control morphological and functional differences between
the two sides of the nervous system. Neural asymmetries are proposed to have important …

Hemispheric asymmetries represent one of the major organizational principles in vertebrate
neurobiology, but their molecular determinants are not well understood. For handedness …

Handedness is the single most studied aspect of human brain asymmetries. For long it has
been thought to be a monogenic trait that can produce an asymmetrical shift of cerebral …

We aimed to investigate the effect of hand effector and handedness on the cerebral
lateralization of pantomiming learned movements. Fourteen right‐handed and 14 left …

Lateralization of brain and behaviour has been the topic of research for many years in
neuropsychology, but the factors guiding its development remain elusive. Based on sex …
