    Gain, not concomitant changes in spatial receptive field properties, improves task performance in a neural network attention model

    Kai J Fox, Daniel Birman, Justin L Gardner
    Simple modifications to early stages of the visual hierarchy, such as gain changes, can induce complex effects on later stages, but only gain is both necessary and sufficient to explain enhanced perception during spatial attention.

    A prefrontal network model operating near steady and oscillatory states links spike desynchronization and synaptic deficits in schizophrenia

    David A Crowe, Andrew Willow ... Bagrat Amirikian
    Cortical network model suggests a mechanism explaining the link between NMDAR synaptic and spike synchrony deficits observed in a pharmacological monkey model of prefrontal network failure in schizophrenia.

    Sensory dynamics of visual hallucinations in the normal population

    Joel Pearson, Rocco Chiou ... Bard Ermentrout
    A new method for inducing, measuring and modelling visual hallucinations in healthy people reveals that hallucinations share common underlying mechanisms with normal sensory perception.

    Model discovery to link neural activity to behavioral tasks

    Jamie D Costabile, Kaarthik A Balakrishnan ... Martin Haesemeyer
    Model identification of neural encoding is an accessible system for the analysis of neural data that allows identifying and characterizing arbitrary relationships between neural activity and task-related variables such as behavior, stimuli, or internal states.

    Using an achiasmic human visual system to quantify the relationship between the fMRI BOLD signal and neural response

    Pinglei Bao, Christopher J Purington, Bosco S Tjan
    The lower-level retinotopic visual cortex of humans born without the optic chiasm comprises two independent neuronal populations and forms a versatile model for quantifying the relationship between the fMRI BOLD signal and neural response.

    A unifying mechanism governing inter-brain neural relationship during social interactions

    Wujie Zhang, Maimon C Rose, Michael M Yartsev
    Experiments and modeling suggest that a mechanism involving positive and negative feedback can explain the relationship between the neural activity of socially interacting bats.
