Lefties, southpaws, goofy footers, katy-handeds, mollydookers. Whatever you call them, 10% of the population is left-handed. But are there any differences between their brains and those of their right-handed friends? Why are some people left-handed? Do genetics play a role? And are left-hand folks really more likely to be geniuses? Well you can find out all about the left-handed brain in this episode of Neuro Transmissions! Join Alie as she uncovers what differences there are in the left handed brain vs right handed brain.
