Saccadic suppression as a perceptual consequence of efficient sensorimotor estimation
Humans perform saccadic eye movements two to three times per second. When doing so, the nervous system strongly suppresses sensory feedback for extended periods of time in comparison to movement time. Why does the brain discard so much visual information? Here we suggest that perceptual suppression may arise from efficient sensorimotor computations, assuming that perception and control are fund...
متن کاملDissociable saccadic suppression of pupillary and perceptual responses to light.
We measured pupillary constrictions in response to full-screen flashes of variable luminance, occurring either at the onset of a saccadic eye movement or well before/after it. A large fraction of perisaccadic flashes were undetectable to the subjects, consistent with saccadic suppression of visual sensitivity. Likewise, pupillary responses to perisaccadic flashes were strongly suppressed. Howev...

19 We measured pupillary constrictions in response to full-screen flashes of variable luminance, 20 occurring either at the onset of a saccadic eye movement or well before/after it. A large fraction of 21 peri-saccadic flashes were undetectable to the subjects, consistent with saccadic suppression of 22 visual sensitivity. Likewise, pupillary responses to peri-saccadic flashes were strongly sup...
متن کاملThe Relationship between Saccadic Suppression and Perceptual Stability
Introspection makes it clear that we do not see the visual motion generated by our saccadic eye movements. We refer to the lack of awareness of the motion across the retina that is generated by a saccade as saccadic omission [1]: the visual stimulus generated by the saccade is omitted from our subjective awareness. In the laboratory, saccadic omission is often studied by investigating saccadic ...

always to give rigorous quantitative expression to qualitative concepts. This was encapsulated in his famous review in 1948 of the properties of haem proteins. A notable paper by Wyman and D.W. Allen in 1951 could be said to prefigure what later became known as the allosteric hypothesis. After his return to (more or less) full-time science Wyman developed the theoretical basis of the scheme of ...
