Inflammatory dynamics are tailored to bacterial class through macrophage integration of microbial stimuli and cytokine feedback.

Animals rely on sensory feedback rather than the precise tuning in the nervous system to achieve robust behavioral performances.

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.

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 budding yeast kinesin Kip2 is a polymerase that uses its processive motility in a positive feedback loop to promote microtubule growth.

The feedback inhibitory microcircuit of the dentate gyrus likely boosts pattern separation during gamma oscillations.

Polo kinase recruitment by the protein Spd-2 to the pericentriolar scaffold is a key element of the positive feedback loop which drives the expansion of the mitotic centrosomes in flies.

Lefty-mediated feedback inhibition of Nodal signaling mitigates signaling perturbations, but is dispensable for development.

Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.

Novel evidence for a role of feedback in the perception of uniform surfaces in the human brain suggests that feedback already re-enters at an early visual processing stage.
