We've written here about the presentation at last year's Brain Mapping meeting on functional brain imaging in a dead fish.
And we've written about imaging functional connectivity during rest, based on the observation that the "noise" in functional MRI data ain't just noise, because spatially-correlated low-frequency fluctuations reveal intrinsic functional brain networks.
Well, last week, at the annual meeting of the International Society for Magnetic Resonance in Medicine, Duke University's Drs. T.B. Harshbarger & A.W. Song presented a paper entitled "Connectivity patterns produced without neuronal activity," showing that "... basic vascular fluctuations ... are sufficient to produce 'connectivity' patterns' in ..." a (living) person's calves.
