The male brain larger than the females, but which is more efficient?

Brain size in women is 8% less than men, but according to a recent study does not mean anything.
 Smaller brain does not necessarily mean low intelligence, or Performance & Performing not at the right level. On the contrary, in the case of women's brain, means exactly the opposite. Yes, because a smaller brain about 8%, compared with that of men, with the introduction korrensponson barabarata and more efficiently.
 There was a team of scientists at the University of Madrid and Los Angeles have found that the female brain is more efficient than the male, although initiated by a margin of dimensions that still manages to overcome as well.
 In a study published in the journal "Intelligence" also revealed that in some tasks, the female brain is more efficient than the male: this is the case of inductive reasoning, math skills and an assessment of the evolving situation. On the other hand, males were more efficient in spatial ability. Then, the female brain is slightly more "ecological", although in terms of efficiency equal (or better), neurons and uses less energy. This study shows that with regard to women, the dimensions of brain matter not related to intelligence. So we can not say that he has little brain is not intelligent!
