New Technique Captures The Activity Of An Entire Brain In A Snapshot
When it comes to measuring brain activity, scientists have tools that can take a precise look at a small slice of the brain (less than one cubic millimeter), or a blurred look at a larger area. Now, r...
New Imaging Technique May Find Real Alzheimer's Culprit
PET scans that highlight the tangle-causing protein tau may better predict memory loss of Alzheimer's than older methods, researchers say.
How dangerous are magnetic items near an MRI magnet?
Fun, games and safety implications with a 4 tesla (T) MRI magnet that was about to be decommissioned. Note how magnetic objects let loose tend to oscillate along the magnet bore. That's because the p...
Molecular Imaging Technique Helps Observe Proteins’ Reactions in Real Time
Proteins are complex molecules that are responsible for carrying out all of the processes that sustain life. A better understanding of how these molecules perform their functions can be achieved by le...
Where exactly are the words in your head?
