Hemispheric dominance refers to the specialization of functions in the left and right hemispheres of the brain, such as verbal skills, structural details versus abstracted features, lateralization of music, emotion, memory, and motor skills.
Directional hemispheric dominance has been established for numerous cognitive functions in the human brain. Strong population biases with some functions favoring the left and others the right hemisphere generated the popular idea of an advantageous prototypical division of labor between both halves of the brain, molded by evolution and ...
Hemispheric language dominance is known to associate with hand preference, as atypical right-hemispheric language dominance is more frequent in left-handed than right-handed people (29, 40). Fig. 3.
11 mar 2016 · Hemispheric specialization (HS), or hemispheric dominance, is a nineteenth century concept that relates to the fact that a given hemisphere is the pilot of a given function such as, for example, the left hemisphere is dominant for language and for right-handedness.
propose that genetic variation in handedness is under the control of alleles at a single locus in a gene, that is, it is a monogenic trait. Recent technological advances, such as GWAS, have shown that handedness cannot be controlled by a single gene.
The lateralization of brain function (or hemispheric dominance[1][2] / lateralization [3][4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.
Surveying extensive data in the cognitive sciences, it explores whether hemispheric asymmetry is unique to humans, and discusses models of brain lateralization and how it might have evolved.
