Active dentate granule cells encode experience to promote the addition of adult-born hippocampal neurons
<p><span>The continuous addition of new dentate granule cells, exquisitely regulated by brain activity, renders the hippocampus plastic. However, how neural circuits encode experiences to impact the addition of adult-born neurons remains unknown. Here, we used endoscopic Ca</span><sup>2+</sup><span> imaging to track the real-time activity of individual dentate granule cells in freely-behaving mice.
