  1. A Database of Brains

    aarondubrow writes "Researchers recently created OpenfMRI, a web-based, supercomputer-powered tool that makes it easier for researchers to process, share, compare and rapidly analyze fMRI brain scans from many different studies. Applying supercomputing to the fMRI analysis allows researchers to conduct larger studies, test more hypotheses, and accommodate the growing spatial and time resolution ...

  2. When Cleaning fMRI Data is a Nuisance

    A flaw in data processing could be leading to biases in fMRI brain functional connectivity patterns, according to a new report: The Nuisance of Nuisance Regression. Ironically, two high-profile recent papers about bias are amongst the victims. The new paper, from Pittsburgh's Michael Hallquist and colleagues, is essentially about a case where 2 + 2 = 3. Functional connectivity fMRI (fcMRI) is a ...
