    Uncovering the functional anatomy of the human insula during speech

    Oscar Woolnough et al.
    Direct insular recordings in humans reveal that contrary to several prominent models of speech production, it is not engaged in pre-articulatory planning, but in auditory and somatosensory components of speech.

    Neural tracking of speech mental imagery during rhythmic inner counting

    Lingxi Lu et al.
    A disassociated neural network underlies the dynamic construction of speech mental imagery independent of auditory perception.

    Frontal cortex selects representations of the talker’s mouth to aid in speech perception

    Muge Ozker et al.
    During speech perception, if auditory speech is not informative the frontal cortex will enhance responses in visual regions that represent the mouth of the talker to improve perception.

    Select forelimb muscles have evolved superfast contractile speed to support acrobatic social displays

    Matthew J Fuxjager et al.
    In situ measurements of muscular twitch speed reveal one of the fastest vertebrate limb muscles on record, which evolved in association with extravagant courtship displays that include rapid limb movements.

    Neuronal populations in the occipital cortex of the blind synchronize to the temporal dynamics of speech

    Markus Johannes Van Ackeren et al.
    Blind people re-purpose the brain's visual areas for tracking speech rhythm.

    A neural mechanism of speed-accuracy tradeoff in macaque area LIP

    Timothy Hanks et al.
    To establish a trade-off between the speed and accuracy of a decision, neurons in lateral intraparietal cortex combine evidence bearing on the decision with a signal that incorporates the cost of time into the decision-making process.

    Modulation of tonotopic ventral medial geniculate body is behaviorally relevant for speech recognition

    Paul Glad Mihai et al.
    Ultra-high field neuroimaging dissects the ventral medial geniculate body (vMGB) of the primary auditory pathway from other MGB subregions and reveals that vMGB top-down modulation is relevant for speech recognition.

    Tuning the speed-accuracy trade-off to maximize reward rate in multisensory decision-making

    Jan Drugowitsch et al.
    Building on previous work (Drugowitsch et al., 2014), it is shown that decision-makers adjust their speed-accuracy trade-off flexibly from one moment to the next, based on evidence available from multiple sensory modalities, in order to nearly maximize their reward rate.
    1. Neuroscience

    A double-sided microscope to realize whole-ganglion imaging of membrane potential in the medicinal leech

    Yusuke Tomina, Daniel A Wagenaar
    For the first time, action potentials and subthreshold postsynaptic potentials of almost all individual identifiable neurons within a functional unit of the leech nervous system were simultaneously imaged during sensory processing and behavioral generation.
    1. Neuroscience

    The auditory representation of speech sounds in human motor cortex

    Connie Cheung et al.
    Brain activity patterns in motor cortex differ when we listen to speech as opposed to produce it.
