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.
Researchers look at the myths and the facts about left-handedness.
Researchers have found the earliest evidence to date of right handedness in fossil records dating back 1.8 million years.
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.
Researchers report genes that exhibit the greatest left-right differences in embryos are also implicated in an increased risk of developing schizophrenia.
Researchers suggest that, regardless of where we are from in the world, humans are hardwired to lean to the right when kissing a romantic partner. The findings could have wider implications for neuroscience and cognitive sciences, the researchers report.
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.
According to researchers, the prevalence of being left-handed is lower in children who were breastfed compared to those who were bottle fed. The study proposes breastfeeding may optimize brain lateralization towards dominant handedness.
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.
The preference to use one hand over the other is already defined by the 18th week of gestation, a new study reports.
