Virtual Brain Models Brain Tumor Progression, Effects of Surgery

Structural brain network in a brain tumor patient from the study. Different brain regions are depicted as spheres, whose size indicates the relative importance within the network. The strength and direction of the structural links between them is represented by different colors and width. The brain tumor, a large meningioma, is the orange mass.

Algorithm Speeds Up Medical Image Analysis 1000 Times


Medical image registration is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great detail. Researchers have described a machine-learning algorithm that can register brain scans and other 3-D images more than 1,000 times more quickly using novel learning techniques.


Mechanism Controlling Multiple Sclerosis Risk Identified


Researchers at Karolinska Institutet have now discovered a new mechanism of a major risk gene for multiple sclerosis (MS) that triggers disease through so-called epigenetic regulation. They also found a protective genetic variant that reduces the risk for MS through the same mechanism.


Scientists Discover Fundamental Rule of Brain Plasticity


When one synapse strengthens, neighboring synapses weaken immediately based on the action of a crucial protein called Arc.
