Brain Scans Reveal Left Handedness Could Make People More Creative
Which hand you prefer to write, eat, and brush your teeth with shouldn't really matter in the grand scheme of things.
Yet scientists have been studying human handedness for over a century and discovered it can show a lot about how human brains can work differently.
And since creativity is a measure of how we think – and therefore lives in our brains – any evidence that left-handed people are more creative should be lurking somewhere in our neurocircuitry.
The brains of left-handed people differ from right-handers
It turns out, the brains of left-handed people do, in fact, differ from right-handed folks.
In particular, they display less brain lateralization than right-handers, said Eric Zillmer, a professor of neuropsychology at Drexel University.
Brain lateralization is the idea that the human brain is divided into two halves – the left and right hemispheres – with each half responsible for its own set of functions.
The left side is generally associated with speech, writing, arithmetic, language, and comprehension, while the right side controls creativity, musical skills, and artistic expression – to name just a few functions among many. Read More…
