    Inferring multi-scale neural mechanisms with brain network modelling

    Michael Schirner, Anthony Randal McIntosh ... Petra Ritter
    Hybrid brain network models predict neurophysiological processes that link structural and functional empirical data across scales and modalities in order to better understand neural information processing and its relation to brain function.

    An image-computable model of speeded decision-making

    Paul I Jaffe, Gustavo X Santiago-Reyes ... Russell A Poldrack
    Combining biologically-plausible neural network models of vision with traditional decision-making models enables a detailed characterization of how the visual system extracts representations that guide decisions from raw sensory inputs.

    A neural network model of when to retrieve and encode episodic memories

    Qihong Lu, Uri Hasson, Kenneth A Norman
    A neural network showed better prediction of upcoming states when it was selective in when it encoded and retrieved episodic memories, thereby explaining why humans show this selectivity in studies of naturalistic memory.

    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.
    1. Neuroscience

    What the success of brain imaging implies about the neural code

    Olivia Guest, Bradley C Love
    For brain imaging to be useful despite its limitations in measuring neural activity, the neural code must be smooth both in a traditional sense and functionally.

    Network instability dynamics drive a transient bursting period in the developing hippocampus in vivo

    Jürgen Graf, Vahid Rahmati ... Knut Kirmse
    Two-photon Ca2+ imaging and computational modeling reveal major developmental trajectories of spontaneous activity in developing CA1 and identify important roles of network bi-stability and synaptic input characteristics for hippocampal burstiness before eye opening.

    Estimating and interpreting nonlinear receptive field of sensory neural responses with deep neural network models

    Menoua Keshishian, Hassan Akbari ... Nima Mesgarani
    A comprehensive, data-driven and interpretable nonlinear computational modeling framework based on deep neural networks uncovers different nonlinear transformations of speech signal in the human auditory cortex.
    1. Neuroscience

    An increase of inhibition drives the developmental decorrelation of neural activity

    Mattia Chini, Thomas Pfeffer, Ileana Hanganu-Opatz
    The age-dependent shift of prefrontal excitation-inhibition (E-I) ratio toward inhibition causes sparser and decorrelated activity, while its impairment might relate to neurodevelopmental disorders.
