This image shows adult-born neurons from a subregion of the hippocampus 6 weeks after florescent labeling during the early stages of adult neurogenesis. These neurons exhibit enhanced synaptic plasticity between 4–6 weeks after cell birth, which may play a role in the functioning of the hippocampus. See the article by William Kennedy et al. for more information on the mechanisms contributing to this short period of enhanced plasticity. Cover image: William Kennedy
