  • Using paired recordings from rat entorhinal stellate cells and computational modeling, this study shows that stellate cells in the medial entorhinal cortex (MEC) are almost exclusively connected to each other via inhibitory interneurons in an all-or-none style and that stable grid firing can arise from this recurrent inhibitory circuitry within the MEC.

  • The parahippocampal region of dorsal presubinculum has neurons that preferentially fire based on the direction of the rat's head. The medial entorhinal cortex has neurons that are preferentially active according to grid-like regularity in space. Here, the authors find that pre- and parasubiculum also have these grid cells, which are intermingled with head-direction cells.

  • Spatial navigation and memory depend on neural coding of an organism’s location as well as large-scale knowledge of the environment, but how animals organize information in task-relevant spatial segments is not well understood. Here the authors show that, in rats, perirhinal neurons perform integrative operations, globally specifying where, in the task context, an animal is located.

  • In the hippocampus, coordinates in space are thought to be expressed by the collective firing locations of place cells while the diversity of experience at these locations is encoded by orthogonal variations in firing rates. Here the authors show that these rate variations in CA3 place cells depend on inputs from the lateral entorhinal cortex.

  • Trajectory-dependent firing of neurons within the nucleus reuniens of the thalamus–hippocampus circuit predicted subsequent running direction, and disruption of this circuit reduced predictive firing in the hippocampus, suggesting that the thalamus is a key node in the integration of signals during goal-oriented navigation.

  • It is commonly thought that the dorsal hippocampus is implicated in memory and spatial navigation and the ventral hippocampus in anxiety-related behaviours. On the basis of gene expression, anatomical and electrophysiology studies, Strange and colleagues propose a new model of hippocampal functional anatomy, in which functional long-axis gradients are superimposed on discrete functional domains.

  • Nervous systems recreate properties of the environment in activity patterns referred to as neural representations. In this Review, Moser and colleagues examine how grid cells in the medial entorhinal cortex contribute to the neural representation of external space.

  • The hippocampal formation has been implicated in many disorders — including Alzheimer's disease, schizophrenia and depression — and in cognitive ageing, but how can one area be central to such diverse conditions? Small and colleagues review a large literature of neuroimaging findings and propose a framework of hippocampal dysfunction in which these conditions differentially target distinct subregions of the hippocampal circuit and are associated with either hippocampal hypermetabolism or hypometabolism.

  • Kaitlin Stouffer and colleagues describe Projective Large Deformation Diffeomorphic Metric Mapping (Projective LDDMM), a computational technique to integrate dense 3D tissue level MRI data with sparse measurements from histological or other optical imaging modalities. The authors demonstrate application through projection of neuropathological markers from histological images onto MRI data of the hippocampus.
