Blind vision studies

Fundamental contributions in neuroscience and its projection to the present day

Abstract

Blind vision is called the phenomenon traditionally studied in patients with lesions in their primary visual cortex (V1), who manage to discriminate visual stimuli despite not being aware of having perceived them. From a literature review of the area, milestones in the development of the Blindsight study are presented as a paradigm of neuroscience research, its fundamental contributions, and conceptual and methodological controversies. Data from recent research in the area are also exposed, which raises an emphasis on explaining the phenomenon associated with its neuroanatomic correlates, with recurring findings regarding a central role of the superior colliculus. It is concluded that the study of blindsight as a research paradigm is currently in a process of rethinking both methodological and conceptual.
