  1. Attractor and integrator networks in the brain

    Publication

  2. Cortical ensembles orchestrate social competition through hypothalamic outputs

    Publication
    Most social species self-organize into dominance hierarchies1,2, which decreases aggression and conserves energy3,4, but it is not clear how individuals know their social rank. We …

  3. Place-cell capacity and volatility with grid-like inputs

    Publication
    What factors constrain the arrangement of the multiple fields of a place cell? By modeling place cells as perceptrons that act on multiscale periodic grid-cell inputs, we …

  4. Efficient Inference in Structured Spaces

    Publication
    Whittington et al. demonstrate how network architectures defined in a spatial context may be useful for inference on different types of relational knowledge. These architectures allow for learning …

  5. Robust parallel decision-making in neural circuits with nonlinear inhibition

    Publication
    An elemental computation in the brain is to identify the best in a set of options and report its value. It is required for inference, decision-making, optimization …

  6. The Mind of a Mouse

    Publication
    Large scientific projects in genomics and astronomy are influential not because they answer any single question but because they enable investigation of continuously arising new questions from the …

  7. Systematic errors in connectivity inferred from activity in strongly recurrent networks

    Publication
    Understanding the mechanisms of neural computation and learning will require knowledge of the underlying circuitry. Because it is difficult to directly measure the wiring diagrams of neural circuits …

  8. Efficient and flexible representation of higher-dimensional cognitive variables with grid cells.

    Publication
    We shed light on the potential of entorhinal grid cells to efficiently encode variables of dimension greater than two, while remaining faithful to empirical data on their low …

  9. The intrinsic attractor manifold and population dynamics of a canonical cognitive circuit across waking and sleep

    Publication
    Neural circuits construct distributed representations of key variables—external stimuli or internal constructs of quantities relevant for survival, such as an estimate of one’s location in the …

  10. Grid cell co-activity patterns during sleep reflect spatial overlap of grid fields during active behaviors.

    Publication
    Continuous-attractor network models of grid formation posit that recurrent connectivity between grid cells controls their patterns of co-activation. Grid cells from a common module exhibit stable …

  11. A Map-like Micro-Organization of Grid Cells in the Medial Entorhinal Cortex

    Publication
    How the topography of neural circuits relates to their function remains unclear. Although topographic maps exist for sensory and motor variables, they are rarely observed for cognitive variables …

  12. Inferring circuit mechanisms from sparse neural recording and global perturbation in grid cells

    Publication
    A goal of systems neuroscience is to discover the circuit mechanisms underlying brain function. Despite experimental advances that enable circuit-wide neural recording, the problem remains open in …

  13. Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity.

    Publication
    It is widely believed that persistent neural activity underlies short-term memory. Yet, as we show, the degradation of information stored directly in such networks behaves differently from …
