The right side of the brain is not actually related to being
more creative. At least, not in the popular sense that
creative people are more 'right-brained' than logical or
analytical people are. A study that scanned the brains
of 1,000 people (17)---- no such differences. It is true
that different brain areas are specialised
(18)---- different tasks, including vision, hearing, touch
and the control of movement. And the (19)---- language
areas are in the left hemisphere in 95 percent of
right-handers. (20)----, both hemispheres work together
in almost everything we do and creativity is a
whole-brain process. Painters and sculptors may draw
on mathematical and logical ideas (21)---- visual imagery
and words, just as scientists inventing a new theory may
do the reverse
