Episode 4: Adult Neurogenesis in the News!

Andrew and other members of the Song Lab just published an open access Stem Cell Reports Paper on a new Adeno-associated Virus (AAV) tool that scientists can use to target neural stem cells in high-tech experiments!  Listen to Episode 4 to learn more about neural stem cells and why we should study them.


We cover Andrew’s research focus: serotonin’s effect on adult neurogenesis.  We also speculate a bit on other mechanisms of regulation of neurogenesis, and various functions of the hippocampus.

Adult Neurogenesis

Neurogenesis is the birth and development of new neurons in the developed brain.  This process occurs well into adulthood and helps us form new memories and adapt to new environments. Recently, exercise has been shown to increase adult neurogenesis in mice and other mammals. More adult neurogenesis may lead to more brain power.

Dr. Juan Song’s lab at UNC Chapel Hill studies neurogenesis, and the different neurotransmitter systems that regulate it.  Various neurotransmitters and neuropeptide have been shown to change the rate of neurogenesis in different ways.
