    Stimulus relevance modulates contrast adaptation in visual cortex

    Andreas J Keller et al.
    Cortex dynamically regulates the flow of sensory information by suppressing responses of non-relevant stimuli through mechanisms of adaptation, while boosting sensory responses that are behaviorally important.

    Sequential sensory and decision processing in posterior parietal cortex

    Guilhem Ibos, David J Freedman
    Comparison of feature encoding and top-down cognitive signals gives insight into the role of parietal cortex in mediating decision making.

    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.

    Testing sensory evidence against mnemonic templates

    Nicholas E Myers et al.
    Visual search templates are reactivated only temporarily to act as input filters for target detection.

    Dissociable laminar profiles of concurrent bottom-up and top-down modulation in the human visual cortex

    Samuel JD Lawrence et al.
    Neural activity in the visual system is increased in different layers of the neocortex for bottom-up and top-down modulations.

    Humans can efficiently look for but not select multiple visual objects

    Eduard Ort et al.
    During search for multiple targets, individuals can efficiently prepare to select multiple target objects simultaneously, but the actual selection of those objects from the sensory input is limited.

    Incomplete inhibition of HIV infection results in more HIV infected lymph node cells by reducing cell death

    Laurelle Jackson et al.
    Under conditions where the force of HIV infection per cell is high, partial attenuation of infection with inhibitors can increase the number of live infected cells and may paradoxically be beneficial for viral spread.

    Amygdala neural activity reflects spatial attention towards stimuli promising reward or threatening punishment

    Christopher J Peck, C Daniel Salzman
    Primate amygdala neurons provide a coordinated representation of space and motivational significance whereby amygdala responses to visual stimuli predicting either rewards or aversive stimuli could influence spatial attention in a similar manner.
    1. Neuroscience

    Serial grouping of 2D-image regions with object-based attention in humans

    Danique Jeurissen et al.
    The human visual system groups the individual features of objects together into a coherent whole via a serial, attention-demanding process.

    A transmission-virulence evolutionary trade-off explains attenuation of HIV-1 in Uganda

    François Blanquart et al.
    Analysis of epidemiological data reveals that viral loads in newly HIV-1 infected individuals in Uganda have declined for two decades, and evolutionary modelling shows that attenuation of the virus explains this decline.
