In this study, a woman with these pathologically slowed saccades could modify them in-flight in response to target movements, even when saccadic suppression of displacement prevented conscious awareness of those movements. Thus saccadic suppression of displacement is not complete, in that it provides perceptual information that is sub-threshold to consciousness but which can still be effectively utilised by the oculomotor system. date: 2000-10 date_type: published publication: Vision Research volume: 40 number: 24 publisher: Elsevier Science Ltd pagerange: 3405-3413 refereed: TRUE referencetext: Bahill, A.
