The term cerebral hemisphere concerning to the two parts of the brain that are separated by a cleft, are inversed and asymmetric.Their functional differences are near null, in a few areas have been found and are not differents in all the people.
It is believed that these differences between hemispheres are unique to humans. Since the language and logic processes are more complicated than those instincts, for example: the location.
These hemispheres compete and help each other, despite sounding like a contradiction its how the brain works. Until recently was discovered that with activities several parts of the brain work together.
One curiosity is that the left hemisphere governs mainly the right side of the body and vice versa.
