Brain imaging technology can reveal what a person is thinking about
...h two cognitive exercises: one involved looking at pictures of faces, and a second involved looking at pictures of places or landscapes. Later these same adults were asked to mentally 'imagine' the faces and the ...Specifying alcohol-related brain damage in young women
... shape of brain parts can be examined. FMRI takes pictures of the brain every few seconds, so that researchers can paste together what Tapert calls a "movie" of activity in the brain while the subject is doing a mental task. "FMRI allowed us to examine very subtle changes in blood and oxygen use in the...High-tech scan for blocked arteries matches conventional tests in finding root of symptoms
...of Internal Medicine. EBCT, which takes ultrafast pictures that reveal the presence of blockages by "seeing" the calcium that concentrates in them, is gaining in popularity. The test is seen as faster, more consistent and easier to perform than stress tests. But the equipment usually used to do the scan is e...Providing a bigger view: New imaging device offers better conditions for cancer treatment planning
...so known as CAT scanners, these devices take x-ray pictures of a cancer region from a variety of angles to build a 3D image of the patient's tumor. To get scanned, the patient lies on a table in treatment position. The table then slides so that the body region of interest is inside a large vertical ring or "...New technology tested at Stanford offers unique view inside small intestines
...he soupy contents of the small intestine and takes pictures as it tumbles along. "It doesn't matter if you're looking where you're going, or where you've been," said Van Dam, explaining that the tumbling motion isn't a problem. The M2A capsule is as cost effective as endoscopy, said Van Dam, and could...Individual neurons reveal complexity of memory within the brain
