Brain asymmetry or cerebral asymmetry refers to anatomical, physiological or behavioral differences between the two cerebral hemispheres. The hemisphere that is larger, more active, or superior in performance is dominant.
For a while I thought it has something to do with another problem associated with brain but I guess it seems to be a blessing in disguise. A person having half superior mind. Great!
Cerebral asymmetry are commonly assumed to be uniquely human and even defining characteristics of our species. This is increasingly refuted by the evidence of behavioral asymmetries in non-human species.
