Folk Wisdom Is Not Right About Left Brains

science20.com – We know the left and right side of our brain are specialized for cognitive abilities like language (left hemisphere) and the right hand. That functional lateralization is reflected by morphological asymmetry too. The left and right hemispheres differ subtly in brain anatomy, distribution of nerve cells, connectivity and even neurochemistry.
