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.
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.
Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.
Neurophysiological and behavioral approaches reveal how coordinated input from descending pathways shapes the tuning properties of electrosensory neurons in order to optimize coding of natural stimuli through temporal whitening.
Genetic analysis combined with whole genome sequencing elucidates mechanisms and pathways that form and prevent a specific class of genome rearrangements, foldback inversions, seen in many human cancers.
