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.

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

Compensatory head movements in hawkmoths are influenced by the combined feedback from vision and antennal mechanosensory Johnston’s organs, similar to the combined role of vision and halteres in Diptera.

Distortion and elimination of limb visual feedback affects low-level stretch reflex control, indicating the involvement of a high-level and multimodal representation of the limb state in orchestrating hierarchical sensorimotor control.

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

The assignment of borders to foreground objects occurs in cortical columns in primate visual cortex, and first in deep layers, suggesting a central role for feedback.

Complementary neural codes in frontal and visual cortex support a role for feedback signals in the representation and recognition of partially occluded objects.

Laminar fMRI reveals that adaptive processing involves recurrent processing within visual cortex and top-down influences from posterior parietal cortex via feedback.

Mechanosensors in the antennae of hawkmoths provide rapid sensory feedback for the control of fast flight manoeuvres, which acts in parallel to visual information.

Cortical oscillations in human MEG are lamina-specific, with low-frequency activity predominating in deep, and high-frequency activity in more superficial layers of sensory and motor cortices.
