In this podcast, Connor Wander interviews Andrew Crowther, a fellow graduate student in the Song Lab at UNC Chapel Hill and a member of the Neuroscience curriculum. We cover Andrew\\u2019s research focus: serotonin\\u2019s effect on adult neurogenesis.\\xa0 We also speculate a bit on other mechanisms of regulation of neurogenesis, and various functions of the hippocampus.

Adult Neurogenesis

Adult neurogenesis is the birth and development of new neurons in the developed brain.\\xa0 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 translate into more brain power.

Dr. Juan Song\\u2019s lab at UNC Chapel Hill studies adult neurogenesis, and the different neurotransmitter systems that regulate it.\\xa0 Various neurotransmitters and neuropeptide have been shown to change the rate of neurogenesis in different ways.
