    A compositional neural code in high-level visual cortex can explain jumbled word reading

    Aakash Agrawal et al.
    Viewing a jumbled word activates an efficient visual representation in high-level visual cortex that is matched to stored words in the word form area.

    Excitatory neurons are more disinhibited than inhibitory neurons by chloride dysregulation in the spinal dorsal horn

    Kwan Yeop Lee et al.
    The flow of somatosensory information through the spinal dorsal horn is regulated by synaptic inhibition, which acts upon excitatory and inhibitory interneurons, but the former are especially prone to disinhibition.

    Clusters of synaptic inputs on dendrites of layer 5 pyramidal cells in mouse visual cortex

    Onur Gökçe et al.
    A combination of optogenetics and 2-photon calcium imaging reveals spatial prerequisites for non-linear synaptic summation within a defined cortical connection.

    Attention operates uniformly throughout the classical receptive field and the surround

    Bram-Ernst Verhoef, John HR Maunsell
    A spatially-tuned normalization model accounts for neuronal responses to attended or unattended stimuli that are presented inside the classical receptive field or the surround, and explains various other observations.

    Dendritic NMDA receptors in parvalbumin neurons enable strong and stable neuronal assemblies

    Jonathan H Cornford et al.
    NMDA receptors on PV+ interneurons mediate supralinear integration at feedback synapses from local pyramidal neurons, enabling competing networks to ‘lock’ onto salient inputs.

    Retinal direction selectivity in the absence of asymmetric starburst amacrine cell responses

    Laura Hanson et al.
    Experimental and computational models reveal how parallel 'core' mechanisms shape direction selectivity at the dendrites of starburst amacrine cells and ganglion cells in the mouse retina.

    Biophysics of object segmentation in a collision-detecting neuron

    Richard Burkett Dewell, Fabrizio Gabbiani
    Active dendritic processing enables an individual neuron to discriminate the spatial pattern of synaptic inputs, increasing neural and behavioral selectivity for escaping an impending threat.

    Mapping nonlinear receptive field structure in primate retina at single cone resolution

    Jeremy Freeman et al.
    Multi-electrode recordings and modeling are combined to reveal the transformations of signals from cones to bipolar cells and then to ganglion cells within the primate retina.
    1. Neuroscience

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

    Pinglei Bao et al.
    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.
    1. Neuroscience

    Feed-forward recruitment of electrical synapses enhances synchronous spiking in the mouse cerebellar cortex

    Andreas Hoehne et al.
    Transient recruitment of electrical synapses mediates precisely timed excitation and inhibition to enhance synchronized control of cerebellar cortical output.
