Researchers know what you were about to say; fMRI used to detect memory storage and retrieval
Using functional magnetic
resonance imaging, or fMRI, researchers at the University of Pennsylvania and Princeton University have provided evidence that the act of recalling a memory is a bit like mental time travel. Their study, presented in the Dec. 23 edition of the journ...

resonance imaging (MRI), but at a much finer, cellular resolution, the researchers were able to stitch together two-dimensional slices to create the first 3-D reconstruction of entire neurons in the adult cortex. Dendritic branch tips were measured o...
Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown
