Microglial methylation "landscape" in human brain

In the central nervous system, microglial cells play critical roles in development, aging, brain homeostasis, and pathology. Recent studies have shown variation in the gene-expression profile and phenotype of microglia across ...

To better understand the brain, look at the bigger picture

Researchers have learned a lot about the human brain through functional magnetic resonance imaging (fMRI), a technique that can yield insight into brain function. But typical fMRI methods may be missing key information and ...

How brain cells compensate for damage from a stroke

A study from UCLA neurologists challenges the idea that the brain recruits existing neurons to take over for those that are lost from stroke. It shows that in mice, undamaged neurons do not change their function after a stroke ...

'Jumping' DNA regulates human neurons

The human genome contains over 4.5 million sequences of DNA called "transposable elements," virus-like entities that "jump" around and help regulate gene expression. They do this by binding transcription factors, which are ...
