And for individuals with neurodegenerative conditions such as Alzheimer’s and Parkinson’s, the loss of cognitive function often accompanied by mood disorders such as anxiety is a harrowing experience. One way to push back against cognitive decline and anxiety would be to spur the creation of new neurons. For the first time, University of North Carolina School of Medicine scientists have targeted a specific kind of neuron in mice to increase the production of neural stem cells and spur on the creation of new adult neurons to affect behavior.
Targeting these cells, as reported in the journal Nature Neuroscience, modulated memory retrieval and altered anxiety-like behaviors in mice...
