Résumé
Classical literature on blindsight described that some patients with lesions to the primary visual cortex could respond to visual stimuli without subjective awareness. Recent studies addressed more complex arguments on the conscious state of blindsight subjects such as existence of partial awareness, namely "feeling of something happening" in the lesion-affected visual field, termed 'type II blindsight', and high-level performance in complex cognitive tasks in blindsight model monkeys. Endeavors to clarify the visual pathways for blindsight revealed the parallel thalamic routes mediating the visual inputs from the superior colliculus to extrastriate and frontoparietal cortices, which may underlie the flexible visuomotor association and cognitive control in the blindsight subjects. Furthermore, involvement of post-lesion plasticity is suggested for these neural systems to operate.
