    Working memory capacity of crows and monkeys arises from similar neuronal computations

    Lukas Alexander Hahn, Dmitry Balakhonov ... Jonas Rose
    Despite differences in cellular architecture the brains of monkeys and crows produce comparable limits of working memory with comparable mechanisms.

    CA1 cell activity sequences emerge after reorganization of network correlation structure during associative learning

    Mehrab N Modi, Ashesh K Dhawale, Upinder S Bhalla
    As mice learn to associate events separated in time, neurons within the CA1 region of the hippocampus progressively reorganize their firing patterns, leading to a relay of cellular activity that bridges the two events.

    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.
