    A transformation from temporal to ensemble coding in a model of piriform cortex

    Merav Stern et al.
    A spiking network model that examines the transformation of odor information from olfactory bulb to piriform cortex demonstrates how intrinsic cortical circuitry preserves representations of odor identity across odorant concentrations.

    Fast and flexible sequence induction in spiking neural networks via rapid excitability changes

    Rich Pang, Adrienne L Fairhall
    Biologically plausible changes in the excitabilities of single neurons may suffice to selectively modulate sequential network dynamics, without modifying of recurrent connectivity.

    UP-DOWN cortical dynamics reflect state transitions in a bistable network

    Daniel Jercog et al.
    Population cortical recordings and computational network modeling support a novel mechanism underlying spontaneous UP-DOWN dynamics consisting on non-rhythmic transitions between a silent attractor and a low-rate inhibition-stabilized attractor.

    Microsaccadic sampling of moving image information provides Drosophila hyperacute vision

    Mikko Juusola et al.
    New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.

    A geometric attractor mechanism for self-organization of entorhinal grid modules

    Louis Kang, Vijay Balasubramanian
    The hierarchy of entorhinal grid cell modules with constant scale ratios can self-organize through a new geometrically organized attractor mechanism.
