The neural correlates of the visual consciousness in schizophrenia: an fMRI study
European Archives of Psychiatry and Clinical Neuroscience August 19, 2020 Stéphanie Lefebvre, É. Very, Renaud Jardri et al.
People with schizophrenia have a higher visual detection threshold than healthy controls, meaning they need stronger visual input to become consciously aware of it. Brain imaging showed that during conscious vision, patients failed to activate occipital areas as strongly as controls; during unconscious vision, they failed to activate a widespread network; and during the moment of becoming conscious of a visual stimulus, they failed to activate the anterior cingulate cortex.
