Scientists have long known that handedness is partly shaped by genes. But it wasn’t until 2019 that they identified differences in parts of the DNA of left- and right-handers. The study, which also analyzed brain scans of 9,000 British subjects, found that in lefties, the parts of the...
AThe probability that two right-handed people would have a left-handed child is only about 9. 5 percent. The chance rises to 19. 5 percent if one parent is a lefty and 26 percent if both parents are left-handed: The preference, however, could also stem from an infant’s imitation of ...

Its focus on sex, handedness, and developmental differences is critical to the derivation of a better perspective on how future research should be conducted in this expanding science. Iaccino begins by explaining basic brain structures and types of cognitive styles assigned to each hemisphere. He ...
—How many calories can the brain burn by thinking? In about 5 percent of right-handed people, the key language-processing centers are on the right sides of the brain, and in 30 percent of left-handed people, these centers are on the right side of the brains, Dubuc wrote. Plus, in ...
It was concluded that the right hand (left brain) determines left-handedness; the neural structures only on the left side exhibit pronounced plastic changes to genetic and environmental influences in left-handers. 展开 关键词: left-handedness hand preference hand skill cerebral lateralization visio-...

Sex Differences in the Human Brain Laura S.Allen,Roger A.Gorski, inEncyclopedia of the Human Brain, 2002 IV.FHandedness A complex relationship exists between sex, handedness, and brain organization. Most right-handed people have left-sided language lateralization and right hemisphere specialization ...
How is being right-handed or left-handed related to the brain? “Left-Brained” and “Right-Brained” People A widespread myth suggests that some people, whose left hemisphere is dominant overall, are more quantitative, logical, and analytical, while right-brained individuals are more emotional...
