Throughout adulthood, new neurons are continuously added to the dentate gyrus, a hippocampal subregion that is important in spatial learning. Whether these adult-generated granule cells become functionally integrated into memory networks is not known. We used immunohistochemical approaches to visualize the recruitment of new neurons into circuits supporting(More)
In the hippocampus, the production of dentate granule cells (DGCs) persists into adulthood. As adult-generated neurons are thought to contribute to hippocampal memory processing, promoting adult neurogenesis therefore offers the potential for restoring mnemonic function in the aged or diseased brain. Within this regenerative context, one key issue is(More)
New neurons are continuously generated in the subgranular zone of the hippocampus throughout adulthood, and there is increasing interest as to whether these new neurons become functionally integrated into memory circuits. This protocol describes the immunohistochemical procedures to visualize the recruitment of new neurons into circuits supporting spatial(More)
Long-term memories are thought to depend upon the coordinated activation of a broad network of cortical and subcortical brain regions. However, the distributed nature of this representation has made it challenging to define the neural elements of the memory trace, and lesion and electrophysiological approaches provide only a narrow window into what is(More)
In the water maze, mice are trained to navigate to an escape platform located below the water's surface, and spatial learning is most commonly evaluated in a probe test in which the platform is removed from the pool. While contemporary tracking software provides precise positional information of mice for the duration of the probe test, existing performance(More)
