Document Summary

Real: entirely created by the brain (what perceived) We do not use only 10% of our brain: we use all of it at one point or another. People are not born with all the brain cells we will ever have. They can be created in adults even (field of neuroplasticity). Myth: left-brain dominant individuals are logical and analytic, whereas right brain dominant individuals are more creative and intuitive. True: left relatively more important language, right relatively more important for understand space, but not entirely dependent. Corpus collosum: two hemispheres densely interconnected, any specialization based on hemisphere only relative.
