    Sensory experience inversely regulates feedforward and feedback excitation-inhibition ratio in rodent visual cortex

    Nathaniel J Miska et al.
    Sensory deprivation suppresses cortical responsiveness through a selective remodeling of excitatory and inhibitory microcircuit motifs, by simultaneously amplifying feedforward and suppressing feedback excitation.

    Distributed task-specific processing of somatosensory feedback for voluntary motor control

    Mohsen Omrani et al.
    Somatosensory feedback is transmitted to many sensory and motor cortical regions within 25 milliseconds and ongoing behavioural tasks alter the spatiotemporal pattern of this perturbation-related activity, supporting rapid motor responses to attain behavioural goals.

    The Ca2+ transient as a feedback sensor controlling cardiomyocyte ionic conductances in mouse populations

    Colin M Rees et al.
    Feedback sensing of the intracellular calcium concentration suffices to reproduce the diversity of ionic conductances underlying normal cardiac electromechanical function in a genetically diverse population of mice.

    Mechanosensory neurons control the timing of spinal microcircuit selection during locomotion

    Steven Knafo et al.
    Bioluminescence monitoring and selective silencing in zebrafish larva reveal a novel sensorimotor circuit modulating speed in the moving spinal cord.

    Quantification of gait parameters in freely walking wild type and sensory deprived Drosophila melanogaster

    César S Mendes et al.
    Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.

    Inhibitory control of correlated intrinsic variability in cortical networks

    Carsen Stringer et al.
    A new cortical network model fit directly to multi-neuron recordings reveals that local inhibitory feedback can control neural dynamics, modulate brain state and enhance sensory processing.

    Body side-specific control of motor activity during turning in a walking animal

    Matthias Gruhn et al.
    Turning in an insect is the combined result of body-side-specific modifications in processing of local sensory feedback, and modification of local central pattern generator activity.

    Towards deep learning with segregated dendrites

    Jordan Guerguiev et al.
    A multi-compartment spiking neural network model demonstrates that biologically feasible deep learning can be achieved if sensory inputs and higher-order feedback are received by different dendritic compartments.

    Activity of the C. elegans egg-laying behavior circuit is controlled by competing activation and feedback inhibition

    Kevin M Collins et al.
    The neural circuit that regulates egg-laying behavior in nematode worms is activated by egg production, coupled to the circuit that generates movement, and inhibited by sensory feedback from egg release.
