This week's multimedia presentation is made of animated gifs. Yep, images that [should] play on all computer systems, of brain scans rendered in small animated .gif files (around 1 mb each, 4 mb for the larger orthogonal slices with three views). Artist/scientist/research assistant Mark Dow created these mesmerizing animations along with some earlier Quicktime animations; visit his page for more. 
Above: Human brain, three orthogonal T1 weighted MRI slice sets.
Left: saggital T1 weighted MRI slices. Right: coronal T1 weighted MRI slices.
Thank you for permissions, Mark! Make more? Fly-ins and spinning brains are beautiful . Also check out Mark's Brain art fodder page; more on that later.
