    The SSVEP tracks attention, not consciousness, during perceptual filling-in

    Matthew J Davidson, Will Mithen ... Naotsugu Tsuchiya
    The strength of frequency-tagged neural activity during perceptual filling anti-correlates with the contents of consciousness, yet positively correlates with a neural measure of attention, dissociating these often confounded brain processes.

    Prior probability cues bias sensory encoding with increasing task exposure

    Kevin Walsh, David P McGovern ... Redmond G O'Connell
    With extended practice, stimulus expectations modulate activity in early visual areas that encode the sensory evidence for perceptual choices.

    Stimulus-induced gamma rhythms are weaker in human elderly with mild cognitive impairment and Alzheimer’s disease

    Dinavahi VPS Murty, Keerthana Manikandan ... Supratim Ray
    Visual narrow-band gamma rhythms are reduced in mild cognitive impairment and Alzheimer’s disease, confirming previous rodent research and forming crucial first steps for development of EEG-based biomarkers for humans.

    Social aversive generalization learning sharpens the tuning of visuocortical neurons to facial identity cues

    Yannik Stegmann, Lea Ahrens ... Matthias J Wieser
    Measures of visuocortical activity during aversive generalization learning revealed sharpened representations of facial identity, reflecting inhibitory interactions between neuronal populations that represent facial features associated with threat versus safety.

    The role of premature evidence accumulation in making difficult perceptual decisions under temporal uncertainty

    Ciara A Devine, Christine Gaffney ... Redmond G O'Connell
    Temporal uncertainty interferes with the timely onset of evidence accumulation in perceptual decision making prompting the brain to rely instead on statistical regularities in the temporal structure of the environment.

    Internal neural states influence the short-term effect of monocular deprivation in human adults

    Yiya Chen, Yige Gao ... Jiawei Zhou
    Having the eye open under the patch, even though this does not change the exogenous stimulation because the eye is occluded, will result in an enhanced short-term effect for ocular dominance due to the internal neural states.

    Humans strategically shift decision bias by flexibly adjusting sensory evidence accumulation

    Niels A Kloosterman, Jan Willem de Gee ... Johannes Jacobus Fahrenfort
    Decision-makers are able to intentionally control neural excitability to strategically bias sensory evidence accumulation towards the decision bound that maximizes reward within a given ecological context.

    The emergence of visual category representations in infants’ brains

    Xiaoqian Yan, Sarah Shi Tung ... Kalanit Grill-Spector
    Scalp electroencephalography combined with a frequency tagging method reveals that distinct responses to daily categories emerge at different ages in infants.
    1. Neuroscience

    Attention periodically samples competing stimuli during binocular rivalry

    Matthew J Davidson, David Alais ... Naotsugu Tsuchiya
    A combined behavioural and electroencephalographic approach investigating the covert allocation of attention shows evidence for distributed periodic sampling away from a conscious visual image.
    1. Neuroscience

    Causal role of the frontal eye field in attention-induced ocular dominance plasticity

    Fangxing Song, Xue Dong ... Min Bao
    A series of experiments suggest that the fronto-parietal attentional network is involved in controlling eye-based attention, and FEF plays a crucial causal role in generating the attention-induced ocular dominance shift.
