Functional Connectivity Architecture of the Human Brain
2014
The Neuroscientist
Preserved Fulltext
We propose that a series of changes in connectivity architecture occurred in response to the pressure for processing efficiency in the enlarged brain. ...
We then offer a hypothesis about how the cortical surface expansion during human evolution may have led to remarkable intersubject variability in brain connectivity. ...
For example, the mixture of variability can significantly confound the findings when studying individual differences in the language network. ...

We applied an MRI technique known as diffusion tensor tractography to reveal the morphology of the white matter in vivo by mapping directions of maximum water diffusion in brain tissue. ...
