    Improving emotional-action control by targeting long-range phase-amplitude neuronal coupling

    Bob Bramson et al.
    Non-invasive manipulation of endogenously coupled neural rhythms enhances human control of social-emotional actions.

    Cortical excitability controls the strength of mental imagery

    Rebecca Keogh et al.
    Visual and prefrontal cortex excitability predict individual differences in visual imagery strength, and modulating excitability in these cortical regions causally alters the strength of visual imagery.

    Externally induced frontoparietal synchronization modulates network dynamics and enhances working memory performance

    Ines R Violante et al.
    Externally induced synchronous/desynchronous oscillations during working memory performance reveal distinct patterns of brain activity and connectivity across large-scale networks recruited by the task.

    Modulation of GABA and resting state functional connectivity by transcranial direct current stimulation

    Velicia Bachtiar et al.
    Building on previous work (Stagg et al., 2014), it is shown that transcranial direct current stimulation modulates local GABA concentration and functional connectivity in the human motor cortex.
    1. Neuroscience

    Response repetition biases in human perceptual decisions are explained by activity decay in competitive attractor models

    James J Bonaiuto et al.
    Residual activity from previous trials in a biophysical decision network model causes biases in choice behavior such that a previous response is more likely to be repeated.

    The causal role of the somatosensory cortex in prosocial behaviour

    Selene Gallo et al.
    A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.

    The primary σ factor in Escherichia coli can access the transcription elongation complex from solution in vivo

    Seth R Goldman et al.
    The sigma subunit of bacterial RNA polymerase, classically known as an initiation factor, can also operate as an elongation factor with effects that vary with growth phase.

    An integrin/MFG-E8 shuttle loads HIV-1 viral-like particles onto follicular dendritic cells in mouse lymph node

    Chung Park, John H Kehrl
    Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.

    Structural basis of transcription arrest by coliphage HK022 Nun in an Escherichia coli RNA polymerase elongation complex

    Jin Young Kang et al.
    Cryo-electron microscopy structures show how coliphage HK022 Nun blocks Escherichia coli RNA polymerase translocation by mediating multiple interactions between the RNA polymerase and nucleic acids.

    Selective sorting and destruction of mitochondrial membrane proteins in aged yeast

    Adam L Hughes et al.
    A new mitochondrial protein degradation pathway selectively sorts and destroys a subset of the mitochondrial membrane proteome to protect mitochondria in times of stress.
