A Gene Variant Linked to Alzheimer’s May Disrupt Myelin Production
A Gene Variant Linked to Alzheimer’s May Disrupt Myelin Production
The APOE4 variant causes cholesterol buildup in the cells that make protective fatty sheaths for neurons, possibly helping explain its role in neurodegeneration.

Myelin’s Role in Motor Learning
Ashley P. Taylor | Oct 16, 2014 | 3 min read
The production of new myelin in the brain—a function of non-neuronal glial cells—may be necessary for motor learning, a mouse study shows.
Remodeling Myelin
