Grey Matter News and Research

RSS

Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and both unmyelinated axons and myelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries.

Genetic and lifestyle factors linked to brain network aging, study reveals

Research highlights the impact of genetic and lifestyle factors on a brain network particularly sensitive to aging, schizophrenia, and Alzheimer's disease, using data from nearly 40,000 UK Biobank participants to investigate modifiable risk factors and genetic associations.
