Re-evaluating circuit mechanisms underlying pattern separation (2019, neutral): “Several studies additionally reported that putative granule cells often had multiple place fields (Jung and McNaughton, 1993; Leutgeb et al., 2007; Alme et al., 2010; Park et al., 2011), further confounding the concept of sparse granule cell coding.”

Sparse activity of identified dentate granule cells during spatial exploration (2016, methodology): “Extracellular recordings in foraging rodents have in fact revealed that only a tiny minority of principal neurons – putative granule cells (GCs) – is active during behavior, while the rest are silent (Jung and McNaughton, 1993; Skaggs et al., 1996; Neunuebel and Knierim, 2012).”
Distinct Determinants of Sparse Activation during Granule Cell Maturation (2013, background): “…It is well established that the DG uses sparse population coding with only a small percentage of GCs activated in response to physiological stimuli (Jung and McNaughton, 1993; Chawla et al., 2005; Ramirez-Amaya et al., 2006; Kee et al., 2007; Stone et al., 2011; Neunuebel and Knierim, 2012).”

Place cells, grid cells, and the brain's spatial representation system. (2008, background): “The sparse firing of the granule cells ( Jung & McNaughton 1993, Chawla et al. 2005, Leutgeb et al. 2007a) and the formation of one-to-one detonator synapses between granule cells and pyramidal cells in CA3 (Claiborne et al. 1986, Treves & Rolls 1992) may jointly contribute to decorrelation of…”
Environment-specific expression of the immediate-early gene Arc in hippocampal neuronal ensembles (1999, result): “In agreement with neurophysiological data, Arc induction in CA3 was similar to CA1, whereas a smaller proportion of cells were labeled in the dentate gyru”
A computational principle for hippocampal learning and neurogenesis (2005, background): “The principal cells of the DG greatly outnumber those of the EC (by a factor of five in the rat (Amaral et al., 1990)) while having much lower activity levels (below 0.5 Hz (Barnes et al., 1990; Jung and McNaughton, 1993)).”
Hippocampal mechanisms for the context-dependent retrieval of episodes (2005, unknown): “The formation of distinct representations in dentate gyrus is consistent with the low probability of finding dentate gyrus place cells and their small place fields (Barnes et al., 1990; Jung & McNaughton, 1993).”
Enhanced synaptic plasticity in newly generated granule cells of the adult hippocampus (2004, background): “In vivo recordings suggest that dentate gyrus granule cells fire action potentials related to the location of the animal in the spatial environment and the phase of the hippocampal theta oscillation (5–8 Hz”
Spatial cognition and neuro-mimetic navigation: a model of hippocampal place cell activity (2000, background): “Place cells have been observed in the hippocampus proper (CA3 and CA1 pyramidal cells) [38, 62], and in other extra-hippocampal areas such as the dentate gyrus [26], the entorhinal cortex [4, 45], the subiculum [4, 55], and the parasubiculum [59].”
