    Microsaccades as a marker not a cause for attention-related modulation

    Gongchen Yu, James P Herman ... Richard J Krauzlis
    Midbrain neurons display attention-related modulation even in the absence of microsaccades, demonstrating that shifts of attention can be dissociated from the generation of microsaccades.

    Microsaccadic sampling of moving image information provides Drosophila hyperacute vision

    Mikko Juusola, An Dau ... Jouni Takalo
    New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

    Instantaneous movement-unrelated midbrain activity modifies ongoing eye movements

    Antimo Buonocore, Xiaoguang Tian ... Ziad M Hafed
    Sensory activity within the superior colliculus is read out by downstream motor structures and contributes to individual saccade kinematics with single spike precision.

    Rapid stimulus-driven modulation of slow ocular position drifts

    Tatiana Malevich, Antimo Buonocore, Ziad M Hafed
    Slow, continuous changes in eye position when gaze is fixed, previously believed to be random drifts, are shown to exhibit highly systematic and short-latency response characteristics to visual stimuli.

    Multi-level processing of emotions in life motion signals revealed through pupil responses

    Tian Yuan, Li Wang, Yi Jiang
    Intact and local emotional biological motion exerted distinct influences on pupil responses, wherein the emotional modulation observed in intact biological motion is linked to individual autistic traits.

    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.

    Jointly looking to the past and the future in visual working memory

    Baiwei Liu, Zampeta-Sofia Alexopoulou, Freek van Ede
    When memorising dynamic visual objects, the brain codes for both the past and the anticipated future object location and co-activates both codes when selecting memories for guiding behaviour.

    Brain state and cortical layer-specific mechanisms underlying perception at threshold

    Mitchell P Morton, Sachira Denagamage ... Anirvan S Nandy
    States of elevated arousal and stable retinal images allow enhanced processing of threshold stimuli in the laminar microcircuits of area V4.

    Surface color and predictability determine contextual modulation of V1 firing and gamma oscillations

    Alina Peter, Cem Uran ... Martin Vinck
    Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.
    1. Neuroscience

    Multiple objects evoke fluctuating responses in several regions of the visual pathway

    Meredith N Schmehl, Valeria C Caruso ... Jennifer M Groh
    Neural fluctuations in multiple areas along the visual cortical hierarchy could allow the brain to represent distinct co-occurring visual stimuli.
