    Cortical response states for enhanced sensory discrimination

    Diego A Gutnisky et al.
    Enhanced perceptual discrimination occurs when ongoing population activity in visual cortex is in a 'silent' mode in which neurons optimize information extraction.

    Inhibitory control of correlated intrinsic variability in cortical networks

    Carsen Stringer et al.
    A new cortical network model fit directly to multi-neuron recordings reveals that local inhibitory feedback can control neural dynamics, modulate brain state and enhance sensory processing.
    1. Neuroscience

    An inhibitory gate for state transition in cortex

    Stefano Zucca et al.
    Two major subtypes of cortical interneurons, the PV and the SST positive cells, causally contribute to the regulation of large-scale state transitions in the cortex.

    Irregular spiking of pyramidal neurons organizes as scale-invariant neuronal avalanches in the awake state

    Timothy Bellay et al.
    Spontaneous, irregular spiking in single cortical pyramidal neurons assembles as neuronal avalanches at the group level identifying a robust scale-invariant organization of resting activity in the awake state.
    1. Neuroscience

    Neural excitability and sensory input determine intensity perception with opposing directions in initial cortical responses

    Tilman Stephani et al.
    Larger evoked responses during initial cortical processing may reflect states of lower excitability.

    Ngn1 inhibits astrogliogenesis through induction of miR-9 during neuronal fate specification

    Jing Zhao et al.
    During neurogenesis, Neurogenin 1 activates the microRNA miR-9, which directly targets the Jak-Stat pathway to inhibit astrogliogenesis.

    Opioids depress breathing through two small brainstem sites

    Iris Bachmutsky et al.
    Opioids stop breathing during overdose by silencing two small brain sites, with just 140 neurons in the breathing rhythm generator exerting the key effect.
    1. Neuroscience

    More homogeneous capillary flow and oxygenation in deeper cortical layers correlate with increased oxygen extraction

    Baoqiang Li et al.
    Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

    Affinity and dose of TCR engagement yield proportional enhancer and gene activity in CD4+ T cells

    Karmel A Allison et al.
    Pre-existing enhancers interpret T cell signaling strength in an analogue manner to direct quantitative changes in gene expression within the context of an overall digital response.

    A population of innate myelolymphoblastoid effector cell expanded by inactivation of mTOR complex 1 in mice

    Fei Tang et al.
    A novel population of hematopoietic cells unmasked by mTORC1 inactivation reveals a new mechanism of innate immune tolerance and a new consequence of defective hematopoiesis.
