Understanding the Male Brain

Until nearly a decade ago, the differences between human male and female brains were not evident to scientists. Although many of the behavioral differences between the sexes were obvious, it was not easy to tell apart the ones that could be attributed to cultural factors from those that resulted from differences in the brain circuits.
This situation changed after the advent of the magnetic resonance imaging technology, which made it possible to watch what happens inside living human brains. By now it is widely known that there is no such thing as an “unisex brain”.
On the video below, Dr. Louann Brizendine talks, in a well-humored way, about how male brains work and change since the womb until mature adulthood. The way a man's brain changes when he becomes a father is particularly interesting and surprising. She also gives nice tips that can help men and women to better understand each other and therefore have better relationships.
In the second half of the video, when the audience asks questions, other interesting subjects such as the “gay brain” and the influence of cultural factors on the development of the brain are discussed.

The short video below explains why and shows what alien life forms might possibly look like.
