When starting out in a new imaging field like diffusion tensor imaging it is easy to be overwhelmed by different processing steps and tools.
A recent publication from Frontiers in Neuroscience tr...

In DTI 101 we described how diffusion tensor imaging estimates brain microstructure by modeling diffusion of water in the brain. We briefly discuss that this is done by using ellipsoid or ball shap...

I present a checklist of acquisition parameters for
inclusion in the methods section of an fMRI paper. The current list expands and
updates the list that was given in the 2008 paper from
Poldrack e...

A recent conversation on Twitter led to the suggestion that
someone compile a list of physiological effects of concern for BOLD. That is, a
list of potentially confounding physiological changes tha...
