A meta-analysis study reveals at least 10.6% of the world's population is left-handed.
Four genetic regions have been identified as playing a role in left-handedness. Three of the four genes were associated with proteins involved in brain development and structure. Neuroimaging revealed those who were left-handed had increased functional connectivity between left and right language networks. Researchers also found correlations between the genetic regions associated with left-handedness and slightly reduced Parkinson's risk, but a slightly increased risk for schizophrenia.
A new study debunks the popular myth that handedness plays a role in the lateralization of number processing in the brain. The study revealed, regardless of which is your dominant hand, the brain's location for number processing is the same.
Researchers look at the myths and the facts about left-handedness.
A new study reveals why most people prefer to cradle a baby on the left side.
Researchers believe some treatments for mental health conditions may be ineffective, or even dangerous for left handed people. A new study reports areas of the brain housing alertness and determination may be on the right side for left dominant people. The new theory suggests the location of a person's neural system for emotion depends on their handedness.
The preference to use one hand over the other is already defined by the 18th week of gestation, a new study reports.
Astros and Dodgers players take note, your batting hand may determine your success in a game. Researchers report baseball players who throw and bat left-handed should have a batting advantage as they have less neurological hemispheric lateralization than right handers.
While many associate left handed people with being more gifted musicians and artists, a new study reveals left handers often outperform their right handed peers in difficult problem solving tasks.
A new study investigates how laterality helped brain asymmetries evolve throughout human history.
