    Behavioral-state modulation of inhibition is context-dependent and cell type specific in mouse visual cortex

    Janelle MP Pakan et al.
    The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.

    First spikes in visual cortex enable perceptual discrimination

    Arbora Resulaj et al.
    A brief time window of visually evoked activity in mouse primary visual cortex is sufficient for perceptual discrimination.
    1. Neuroscience

    A hierarchy of timescales explains distinct effects of local inhibition of primary visual cortex and frontal eye fields

    Luca Cocchi et al.
    The selective effect of local inhibition on diffuse patterns of brain connectivity can be accounted for by an intrinsic hierarchical ordering of cortical timescales.

    Conditioning sharpens the spatial representation of rewarded stimuli in mouse primary visual cortex

    Pieter M Goltstein et al.
    Stimulus-reward learning sharpens the local representation of the visual space while leaving the overall retinotopic map intact.

    Context-dependent signaling of coincident auditory and visual events in primary visual cortex

    Thomas Deneux et al.
    Abrupt sounds boost coincident visual cortex responses which could help localization of sudden audio-visual events.
    1. Neuroscience

    VIP interneurons in mouse primary visual cortex selectively enhance responses to weak but specific stimuli

    Daniel J Millman et al.
    Measurements of visual response to motion of different contrasts along with network modeling reveals a microcircuit in superficial layers of cortex that regulates the gain regime.

    Preserved extrastriate visual network in a monkey with substantial, naturally occurring damage to primary visual cortex

    Holly Bridge et al.
    Even when the primary visual cortical area is absent bilaterally from early life, the rest of a primate visual brain can develop and function normally to support day-to-day visual behaviour.

    Dynamic representation of partially occluded objects in primate prefrontal and visual cortex

    Amber M Fyall et al.
    Complementary neural codes in frontal and visual cortex support a role for feedback signals in the representation and recognition of partially occluded objects.
    1. Neuroscience

    Lamina-specific AMPA receptor dynamics following visual deprivation in vivo

    Han L Tan et al.
    Longitudinal imaging of synapses in the brain shows that sensory deprivation differentially modifies specific synapses within individual neurons across distinct layers of the sensory cortex.
