But even with concussive symptoms just as extreme, brain-injured females were less likely than their injured male peers to show such damage.
For The Slow Mo Guys, nothing is off limits when it comes to documenting extreme, brain-meltingly fast footage that will eventually be slowed down to a snail's pace.
At its extremes, brain development can be sufficiently abnormal as to lead to personality disorders," he said.
Recent studies of transgenic and knockout mouse models, genomic copy-number variants, imprinted-gene expression alterations, and sex-chromosome aneuploidies are revealing examples of 'mirror-extreme' brain and behavior phenotypes, which provide unique insights into neurodevelopmental architecture.
Volumes such as Doreen Kimura's Sex and Cognition [ 1], Simon Baron-Cohen's The Essential Difference: Men, Women and the Extreme Male Brain [ 2], Melissa Hines's Brain Gender [ 3] and Louann Brizendine's The Female Brain [ 4] have reviewed, and in some instances overinterpreted, the current state-of-the-art.
The latest study, from the universities of Cambridge and Utrecht, tests the idea that the disorder may be the result of an "extreme male brain", perhaps compromised by exposure to male sex hormones during brain development in the womb.
In his extreme male brain theory of autism, Baron-Cohen postulates that having a typically male brain was adaptive for ancestral men and having a typically female brain was adaptive for ancestral women.
An extension, the extreme male brain theory, hypothesizes that autism is an extreme case of the male brain, defined psychometrically as individuals in whom systemizing is better than empathizing.
Considering that the extreme male brain theory of autism posits that ASD represents an extreme of the male brain pattern with impaired EQ and enhanced SQ [27], [49] [50], the present findings cast some light on the normal male MNS pattern, as measured with EEG, and lend support to the hypothesis of a dysfunctional MNS in ASD.
