    A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

    Renat N Khaliullin et al.
    Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

    Ultra-Rapid serial visual presentation reveals dynamics of feedforward and feedback processes in the ventral visual pathway

    Yalda Mohsenzadeh et al.
    Reducing visibility with higher image presentation rates increases recurrent processing demands along the visual processing pathway to resolve object recognition.

    A feedback amplification loop between stem cells and their progeny promotes tissue regeneration and tumorigenesis

    Jun Chen et al.
    A newly discovered feedback amplification loop between stem cells and their immediate daughter progenitor cells drives epithelial regeneration and tumor development.

    The inhibitory microcircuit of the substantia nigra provides feedback gain control of the basal ganglia output

    Jennifer Brown et al.
    Negative feedback signals within the substantia nigra regulate the output of the basal ganglia, with implications for disorders such as Parkinson's disease.

    An excitatory cortical feedback loop gates retinal wave transmission in rodent thalamus

    Yasunobu Murata, Matthew T Colonnese
    The absence of functional inhibition is a developmentally transient circuit property of corticothalamic feedback that is essential for the central transmission of spontaneous retinal waves.

    Cerebellar implementation of movement sequences through feedback

    Andrei Khilkevich et al.
    The cerebellum can learn a sequence of responses by using a feedback signal from the previous movement to learn the next one.

    Cerebellar patients have intact feedback control that can be leveraged to improve reaching

    Amanda M Zimmet et al.
    A control system model of cerebellar patients' movements provides insight into the cerebellum's role in reaching and informs a virtual reality intervention to improve patient reaches.

    Tuning of feedforward control enables stable muscle force-length dynamics after loss of autogenic proprioceptive feedback

    Joanne C Gordon et al.
    Running guinea fowl maintain stable running after loss of the stretch reflex in a major ankle extensor muscle, by increasing feedforward muscle activation to maintain ankle stiffness and work output.

    Auditory cortex shapes sound responses in the inferior colliculus

    Jennifer M Blackwell et al.
    Feedback from the mammalian auditory cortex to the midbrain decreases sound selectivity, altering how sounds are processed in the brain.

    Feedback control of Wnt signaling based on ultrastable histidine cluster co-aggregation between Naked/NKD and Axin

    Melissa V Gammons et al.
    An unusual molecular mechanism has been revealed based on ultrastable histidine cluster co-aggregation underlying feedback control of an ancient cell communication pathway.
