Researchers at UCLA “found that parts of the prefrontal cortex take over when the hippocampus, the brain’s key center of learning and memory formation, is disabled. Their breakthrough discovery, the first demonstration of such neural-circuit plasticity, could potentially help scientists develop new treatments for Alzheimer’s disease, stroke and other conditions involving damage to the brain.”

The Dailey Know 
I love our brains. Since this capability has been reaffirmed, I now hope that research turns to looking for the “ingredients” to stimulate synaptogenesis in patients with conditions involving brain damage. I know the initial assault or onset of the disease illicit some increased synaptogenesis, but there’s plenty of room to further encourage the process.
