Neurogenesis (with Carlotta Barelli)

In this episode, we were joined by a special guest, Carlotta Barelli, to discuss the controversy surrounding adult neurogenesis. Are new neurons generated throughout life in humans and, if so, what are the implications?


What is neurogenesis?


Adult neurogenesis and functional plasticity in neuronal circuits (Lledo et al., 2006) https://www.nature.com/articles/nrn1867


Does neurogenesis occur in adult humans?
