IEEE Collabratec

Found this on Facebook ad, looks useful, but maybe a bit overlapping with Mendeley or other tools that area already available. Just set it up to give it a try. :)

terms, jargons...

stimulus = task
fucntional connectivity = correlation
resting state = state of not doing anything
voxels = pixels on the medical image
ROI = region of interest (parts of the brain or a group or regions that are in the same network)
