    Inference of nonlinear receptive field subunits with spike-triggered clustering

    Nishal P Shah, Nora Brackbill ... EJ Chichilnisky
    Nonlinear receptive field subunits in retinal ganglion cells are isolated and characterized by clustering spike-triggered stimuli, and validated on population responses to naturalistic and novel closed loop stimuli.

    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.

    Neural dynamics of semantic categorization in semantic variant of primary progressive aphasia

    V Borghesani, CL Dale ... SS Nagarajan
    Following anterior temporal lobe neurodegeneration, defective semantic representations are compensated via enhanced perceptual processing and associated with a dysregulation of the semantic control system.

    A reservoir of timescales emerges in recurrent circuits with heterogeneous neural assemblies

    Merav Stern, Nicolae Istrate, Luca Mazzucato
    The large range of timescales empirically observed in neural circuits can be naturally explained when neural assemblies of heterogeneous size are recurrently coupled, empowering the neural circuits to efficiently process complex time-varying input signals.

    Covert shift of attention modulates the value encoding in the orbitofrontal cortex

    Yang Xie, Chechang Nie, Tianming Yang
    The orbitofrontal neurons only encode the value of one item, which may be selected by covert attention combining factors of value and visual salience, suggesting a sequential processing mechanism of value information in the brain.

    Mouse V1 population correlates of visual detection rely on heterogeneity within neuronal response patterns

    Jorrit S Montijn, Pieter M Goltstein, Cyriel MA Pennartz
    Heterogeneity of neural responses in mouse cortex correlates better with visual detection than mean population activity.

    Attention stabilizes the shared gain of V4 populations

    Neil C Rabinowitz, Robbe L Goris ... Eero P Simoncelli
    Populations of neurons in the macaque visual cortex are subject to shared fluctuations in gain; these signals exhibit anatomical and functional structure, and their variability is diminished under attention.

    A simple and effective F0 knockout method for rapid screening of behaviour and other complex phenotypes

    François Kroll, Gareth T Powell ... Jason Rihel
    Zebrafish knockouts can be generated in a few hours directly from wild-type eggs and are suitable for studying continuous traits, including behaviour.

    Amplitude modulations of cortical sensory responses in pulsatile evidence accumulation

    Sue Ann Koay, Stephan Thiberge ... David W Tank
    From as early as primary visual cortex and across posterior cortical areas, neural responses to visual pulses during an evidence-accumulation task exhibit a multitude of task-related amplitude modulations/gain changes.
