    Altered hierarchical auditory predictive processing after lesions to the orbitofrontal cortex

    Olgerta Asko, Alejandro Omar Blenkmann ... Anne-Kristin Solbakk
    Orbitofrontal cortex lesions impact the neural correlates of detection of auditory regularity violation at two hierarchical levels of rule abstraction, providing a novel perspective on the role of the orbitofrontal cortex in auditory predictive processing.

    Conscious processing of global and local auditory irregularities causes differentiated heartbeat-evoked responses

    Diego Candia-Rivera, Federico Raimondo ... Jacobo D Sitt
    Brain-heart interactions under the processing of auditory irregularities could help to distinguish whether a patient is in a vegetative state or in a minimally conscious state.

    Contextual and cross-modality modulation of auditory cortical processing through pulvinar mediated suppression

    Xiao-lin Chou, Qi Fang ... Li I Zhang
    Electrophysiological recording and optogenetic manipulation approaches reveal that a multisensory bottom-up SC-LP-A1 pathway plays a role in contextual and cross-modality modulation of auditory cortical processing.

    Abstract rules drive adaptation in the subcortical sensory pathway

    Alejandro Tabas, Glad Mihai ... Katharina von Kriegstein
    Representations in the subcortical sensory pathway do not only adapt to stimulus properties but also rely on the observer’s subjective model of the world.
    1. Neuroscience

    Fast-spiking GABA circuit dynamics in the auditory cortex predict recovery of sensory processing following peripheral nerve damage

    Jennifer Resnik, Daniel B Polley
    Dynamic regulation of feedforward inhibition from parvalbumin-expressing inhibitory neurons is linked to the gradual restoration of cortical sensory processing following auditory nerve damage.

    1. Neuroscience

    Parallel pathways for sound processing and functional connectivity among layer 5 and 6 auditory corticofugal neurons

    Ross S Williamson, Daniel B Polley
    Targeted recordings from subcortical projection neurons in the auditory cortex reveal two cell classes with distinct signatures of sensory processing and different patterns of local and long-range connectivity.

    Intercollicular commissural connections refine the representation of sound frequency and level in the auditory midbrain

    Llwyd David Orton, Adrian Rees
    Deactivation of one side of the auditory midbrain while recording in the other shows that the two sides cooperate in processing frequency and in enhancing the encoding of sound level.

    Post-decision processing in primate prefrontal cortex influences subsequent choices on an auditory decision-making task

    Joji Tsunada, Yale Cohen, Joshua I Gold
    A behavioral model, neuronal recordings, and electrical microstimulation reveal that the ventrolateral prefrontal cortex plays a causal role in evaluating prior decisions and biasing future decisions.

    Coordinated neuronal ensembles in primary auditory cortical columns

    Jermyn Z See, Craig A Atencio ... Christoph E Schreiner
    Auditory cortical columns contain small subsets of neurons with highly synchronous activity (cNEs) that create robust sequences of coordinated activity suitable for enhanced information processing and signal transmission beyond the capability of individual neurons.

    Cell-specific gain modulation by synaptically released zinc in cortical circuits of audition

    Charles T Anderson, Manoj Kumar ... Thanos Tzounopoulos
    Synaptic zinc is a novel modulator of cortical sound processing - a modulator that increases the gain of principal neurons, but reduces the gain of interneurons.
