Place cells are recorded before and after rats fall asleep on a rotating arena. Population activity during sleep-associated 'slow irregular activity' episodes is similar to population activity in the awake state at the location where the rat fell asleep, even though in the meantime the rat has rotated to a different place.

Moser Progressive transformation of hippocampal neuronal representations in 'morphed' environments Neuron 48 2005 345 358 This study shows that there is a smooth noncoherent progression between two well-established hippocampal representations under conditions in which the recording box is gradually morphed from a square to a circle, or vice versa, in small quantifiable steps. Representations are transformed gradually in both CA3 and CA1. The data suggest that hippocampal cell ensembles can represent information along continua. The study also demonstrates that there is strong hysteresis in CA3 during the transition from one shape to another.

Knierim Major dissociation between medial and lateral entorhinal input to dorsal hippocampus Science 308 2005 1792 1794 The key finding here is that cells with spatial firing fields exist only in the medial subdivision of the entorhinal cortex. Cells in the lateral entorhinal cortex show no consistent spatial modulation. A possible implication of these results is that spatial and nonspatial inputs innervate the hippocampus by separate routes.

Moser Spatial representation in the entorhinal cortex Science 305 2004 1258 1264 Cells in layers II and III of the dorsolateral band of the medial entorhinal cortex cells are shown to represent the animal's current location as precisely as place cells in the dorsal hippocampus. In the intermediate and ventromedial bands, cells show weaker spatial modulation, as previously reported [ 20,26,27 ]. The spatial selectivity in the dorsolateral band can be maintained without hippocampal feedback. Thus, spatial information is, to a large extent, computed upstream of the hippocampus.

Moser Microstructure of a spatial map in the entorhinal cortex Nature 436 2005 801 806 This study shows that the firing fields of spatially selective neurons in layer II of the dorsolateral medial entorhinal cortex form a grid-like structure of tessellating equilateral triangles, covering the whole surface of the recording environment for each cell. The grid-like firing structure is maintained independently of external landmarks. Microdomains of neighbouring cells have similar grid spacing and grid orientation, but the vertices of different cells are shifted with respect to each other. Location, direction and distance are thus represented in the same neurons and the whole environment is represented in each microdomain. These data provide evidence for a topographically organized, path-integration-based spatial map in the entorhinal cortex.

Rats are trained in square and circular versions of a box with flexible walls. Place cells are then recorded in a series of intermediate shapes, with the intermediates presented in a semi-random order. As predicted by theoretical models of attractor dynamics, the hippocampal ensembles show a bistable response pattern in the intermediate shapes, adopting either a square-like or circle-like firing pattern.

Moser Distinct ensemble codes in hippocampal areas CA3 and CA1 Science 305 2004 1295 1298 This study demonstrates that there is strong pattern separation in CA3 but not CA1. Place cells are recorded in contexts with overlapping elements. Whereas CA3 ensembles show strong orthogonalization between all pairs of contexts, CA1 cells generally preserve some information about their similarity. New representations develop faster in CA1 than in CA3, which suggests that CA1 cells are more influenced by direct entorhinal input.

    • Differences in hippocampal neuronal population responses to modifications of an environmental context: Evidence for distinct, yet complementary, functions of CA3 and CA1 ensembles
    • A. Vazdarjanova, and J.F. Guzowski Differences in hippocampal neuronal population responses to modifications of an environmental context: evidence for distinct, yet complementary, functions of CA3 and CA1 ensembles J Neurosci 24 2004 6489 6496 Using transcriptional imaging methods, the authors measure the overlap of hippocampal population activity between environments that differ to various extents. In similar environments, the subset of active cells overlaps more in CA3 than in CA1. In more dissimilar environments, the overlap is smaller in CA3 than in CA1. These data provide evidence for nonlinear dynamics in CA3.

Place cells are recorded from CA1 during behavioural testing in three interconnected boxes. Substituting one of the boxes with another one causes remapping in the changed box but not in the rest of the apparatus, suggesting that the global CA1 representation can be stretched to incorporate the new information.

    • S. Leutgeb, J.K. Leutgeb, C.A. Barnes, E.I. Moser, B.L. McNaughton, and M.-B. Moser Independent codes for spatial and episodic memory in the hippocampus Science 309 2005 619 623 This study suggests that hippocampal networks have independent coding schemes for spatial and nonspatial information. Place cells are recorded in CA3 and CA1 under two conditions. When local cues are constant but the test room is varied, both the location and rate of firing change to statistically independent values. When the test room is constant but local cues are varied, firing rates change substantially but firing locations remain fixed. The dissociation is particularly striking in CA3. These orthogonal coding schemes (location versus rate) suggest that information about location on one hand and nonspatial stimuli or events on the other might remain segregated during early stages of hippocampal processing. The information might eventually be associated in the output from the hippocampus.

Encoding is proposed to take place in CA3 when entorhinal inputs are strongest, at the trough of the theta oscillation. Retrieval is suggested to occur by reactivation of intrahippocampal cell ensembles when recurrent inputs are stronger, at the peak of the theta oscillation.
