VCU researchers identify networks of genes responding to alcohol in the brain
...iological pathways, such as the one leading to the production
of myelin. Myelin is a form of molecular insulation that allows nerve cells to send impulses to one another more effectively. Such pathways showed different responses to alcohol in one mouse strain versus the other. As a result, Miles and his colleag...

...dings in the March 3 issue of Neuron. Although the production
of beta amyloid occurs in all brains, healthy brains are able to clear away excess amounts. Brains with Alzheimer's disease, on the other hand, are unable to control beta amyloid accumulation. In monitoring the mice from birth until six months, the r...
