Feedback-driven gain modulation provides a mechanism to generate and maintain invariant sensory representations in the presence of contextual changes by dynamically adapting feedforward sensory processing.
Investigating how an artificial network of neurons controls a simulated arm suggests that rotational patterns of activity in the motor cortex may rely on sensory feedback from the moving limb.

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.

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

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.

A specific neuronal pathway within the auditory system represents information about the statistical prediction and error for incoming sounds, thereby contributing to efficient representation of complex sounds and sound streams in the brain.
Mechanosensors in the antennae of hawkmoths provide rapid sensory feedback for the control of fast flight manoeuvres, which acts in parallel to visual information.
