Newborn brains grow vision and movement regions first

...y high resolution magnetic resonance imaging (MRI) scans on a large group of newborns. The results appear i...n brain development," Gilmore said. However, the scans revealed that brain asymmetry -- or which side of the brain is larger -- was opposite in newborns an...

Lithium builds gray matter in bipolar brains, UCLA study shows

...es at UCLA used computer analysis to analyze brain scans collected by collaborators at the University of Pittsburgh in order to determine whether bipolar patients showed changes in brain tissue and, if so, whether those changes were influenced by lithium treatment. Specifically, they employed high-resoluti...

Fused nasal bones helped tyrannosaurids dismember prey

...chanics of dinosaur skulls, the scientists used CT scans to investigate such factors as teeth bending strength and nasal and cranium strength. The research is published in the journal Acta Palaeontologica Polonica. Tyrannosaurids differ from other dinosaurs in the great robustness of their teeth and sk...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...tudy, researchers compared variations found in the scans of 413 adults who had bipolar disorder with variations found in the scans of 563 healthy adults. By pooling the genetic material of the adults with bipolar disorder, the ...

Traumas like Sept. 11 make brains more reactive to fear

...d to photographs of fearful versus calm faces, the scans of 11 people who were within 1.5 miles of the World Trade Center on Sept. 11, 2001, were compared with those who were living more than 200 miles away at the time; none of the subjects had psychiatric disorders. "We know that looking at fearful face...

Novel system developed to turn data into real-time, interactive 3-D images

...ily applicable to medical images. For instance, CT scans generate large 3- and 4-D data sets. The new technology will produce a 3-D, high quality, real-time image of the data to help physicians and other medical professionals more clearly view, and rapidly extract important diagnostic information about, th...

How the brain's backup system compensates for stroke

..., but that performance quickly recovered. The fMRI scans revealed that during this behavioral recovery, the right PMd and other areas involved in premotor function underwent a compensatory increase in activity. The researchers' experiments also established that this activity increase was functionally speci...

CT scan reveals ancient long-necked gliding reptile

...n be reviewed and reanalyzed in the future. The scans presented to Fraser were not a perfect photograph of the two specimens, rather they were a set of thin slices that had to be processed to obtain information about the animals. Even then, no single slice contained the entire skeleton. Post-scan proce...

Breakthrough developments in rheumatoid arthritis reported

... genetic findings. The group conducted genome-wide scans to identify polymorphisms, or genetic variants, that are associated with the inflammatory condition and can be used to understand the triggers of the disease. This will provide key insights into the pathways underlying rheumatoid arthritis and other ...
