This is a guest post in our #NPGsfn11 blog series and posted on behalf of Jason Snyder. This is cross-posted at Functional Neurogenesis. Previously, I wrote about new SfN data on the role for newborn neurons in regulating emotion. The second half of the SfN meeting rounded out the story because the bulk of the functional presentations focused on the role of new neurons in that other, classic function of the hippocampus: memory. Spanning synaptic plasticity, circuit function, and then linking it all to behavior, we have quite a complete story here.
