Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.

A mouse mutant in which nearly all dentate gyrus granule cells fail to develop provides a new window on the role of the dentate gyrus in spatial learning and memory.

Multiphoton live-imaging illuminates the dynamic underpinnings of how different types of progenitor cells migrate and interact to robustly build the mammalian Dentate Gyrus neural circuitry and new outer neurogenic niche.

Heterogeneity in the population of granule cells in the dentate gyrus, which includes immature and mature neurons with distinct intrinsic properties, contributes to the population's enhanced encoding capabilities and ability to discriminate correlated stimuli.

Mice can learn to press a lever persistently for activation of a dopaminergic projection from the locus coeruleus to the hippocampal dentate gyrus.

An astrocytic scaffold that depends on SOX9 guides embryonic neuronal progenitors toward the developing dentate gyrus.

Iterative immunostaining using 4i enables detailed characterization of complex mouse and human tissues.

The formation of new neurons in the adult dentate gyrus causes a proportion of cortical neurons to transfer their existing connections to the newborn cells.

During development the Sonic Hedgehog protein is produced by epithelial structures and acts at a distance in the brain and perhaps in other organs.

By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.
