Left-handers make up about 10.6 percent of the world’s population. Sebastian Ocklenburg, PhD, talks about why handedness and other brain asymmetries exist; the genetic and environmental factors that influence handedness; whether there’s any truth to the stereotype that lefties are more creative; why “pawedness” is common in cats, dogs, and other non human animals; and why left-handed people are underrepresented in brain research.
