    Acoustic shadows help gleaning bats find prey, but may be defeated by prey acoustic camouflage on rough surfaces

    Elizabeth L Clare, Marc W Holderied
    Some species of bats hunt for insects that are resting on surfaces by detecting interruptions in the echoes from that surface, suggesting that resting on rough surfaces may help insects to evade detection by echolocation.

    How oscillating aerodynamic forces explain the timbre of the hummingbird’s hum and other animals in flapping flight

    Ben J Hightower, Patrick WA Wijnings ... David Lentink
    A first-principles acoustics model reveals how the acoustic spectrum generated by flapping wings originates from oscillating aerodynamic forces, and is validated by in vivo aerodynamic force measurements and acoustic holography.

    Detecting changes in dynamic and complex acoustic environments

    Yves Boubenec, Jennifer Lawlor ... Bernhard Englitz
    Psychophysics experiments and EEG recordings reveal that people's performance in detecting unexpected changes in complex auditory scenes can be modeled as a process of sensory evidence accumulation.

    Prefrontal cortex supports speech perception in listeners with cochlear implants

    Arefeh Sherafati, Noel Dwyer ... Jonathan E Peelle
    The use of high-density optical brain imaging in listeners with cochlear implants shows increased activity in frontal cortex during speech perception compared to those with normal hearing.

    Push-pull competition between bottom-up and top-down auditory attention to natural soundscapes

    Nicholas Huang, Mounya Elhilali
    Everyday soundscapes dynamically engage attention towards target sounds or salient ambient events, with both attentional forms engaging the same fronto-parietal network but in a push-pull competition for limited neural resources.

    Correlative all-optical quantification of mass density and mechanics of subcellular compartments with fluorescence specificity

    Raimund Schlüßler, Kyoohyun Kim ... Jochen Guck
    The combination of optical diffraction tomography and Brillouin microscopy in a single setup enables to quantitatively map the viscoelastic properties of cellular compartments such as aggregates and stress granules in vivo.

    Neurophysiological evidence of efference copies to inner speech

    Thomas J Whitford, Bradley N Jack ... Mike E Le Pelley
    The silent production of words in one's mind generates an efference copy that is similar in nature to the efference copy associated with overt vocalization.

    Categorical representation from sound and sight in the ventral occipito-temporal cortex of sighted and blind

    Stefania Mattioni, Mohamed Rezk ... Olivier Collignon
    The categorical organization of the ventral occipito-temporal cortex, typically thought to be a visual region, is actually partially independent of visual input and even visual experience.

    Cortical encoding of acoustic and linguistic rhythms in spoken narratives

    Cheng Luo, Nai Ding
    In the processing of spoken narratives, bottom-up acoustic cues and top-down linguistic knowledge separately contribute to neural construction of linguistic units.
    1. Neuroscience

    Dynamic top-down biasing implements rapid adaptive changes to individual movements

    Lucas Y Tian, Timothy L Warren ... Michael S Brainard
    Multi-area recordings reveal how communication between two songbird brain areas conveys a top-down bias that adaptively modifies ongoing singing to support context-specific vocal learning.
