Temporally tagging new memories

Cells in the dentate gyrus of the hippocampus demonstrate activity that is selective for experiences that occurred during a particular time interval. This selectivity is greatly reduced when adult neurogenesis, the birth of new neurons in the adult brain, is suppressed. These results suggest a role for the dentate gyrus and adult neurogenesis in linking temporally proximal events and separating events that occurred far apart in time. Read our publication here.
