Hemispheric specialization (HS) is a hemisphere-dependent relationship between a
cognitive, sensory, or motor function and a set of brain structures. It includes
both the hosting by a given hemisphere of specialized networks that have unique
functional properties and mechanisms that enable the inter-hemispheric
coordination necessary for efficient processing. Long derived from
neuropsychological and behavioral observations, knowledge of HS is currently
being profoundly modified by cutting-edge neuroimaging research that focuses both
on the neural implementation of HS for language, visuospatial functions, and
motor control/handedness across development and on the analysis of interactions
between brain regions within and across hemispheres. New findings reveal the
fundamental role of lateralization in the large-scale architecture of the human
brain, whose ontogenesis has begun to be investigated with genetic-heritability
brain mapping.
