Chemical Reaction Keeps Stroke Damaged Brain from Repairing itself

When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer’s. Researchers recently discovered that nitric oxide not only damages neurons, it also shuts down the brain’s repair mechanisms.

Dickkopf Makes Fountain of Youth in the Brain Run Dry

Scientists have discovered that significantly more neurons are generated in the brains of older animals if the signaling molecule Dickkopf-1 is turned off. The results give rise to the question whether the function of Dickkopf-1 may be turned off using drugs to prevent age related cognitive decline.

Scientists Reverse Memory Loss in Animal Brain Cells

Using the nerve cells of sea snails, researchers reverse memory loss by determining when cells were primed for learning. Retraining cells with the use of an optimized training schedule helped compensate for memory loss.
