In this study, we investigated whether individuals with congenital blindness (CB) exhibit similar connectivity patterns\u2014potentially reflecting innate brain wiring. Our analysis revealed that, in CB participants, orbital EPI signals still show correlations with motor cortex activity, albeit with reduced association to the visual cortex. Interestingly, the temporal dynamics of these eye movement-related signals were markedly different in CB compared to sighted individuals. Some blind participants even displayed asynchronous orbital EPI signals between their two eyes, each linked to distinct neural networks. These results imply that while the motor\u2013oculomotor pathways remain partially intact in the absence of vision, significant functional reorganization occurs. This reconfiguration likely stems from the lack of visual feedback and the reduced capacity of CB individuals to perceive or intentionally control their eye movements.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer eplus-wrapper\"><\/div>\n\n\n\n<p class=\" eplus-wrapper\"><strong>Autors<\/strong>: Cemal Koba,\u00a0Alessandro Crimi,\u00a0Olivier Collignon,\u00a0Emiliano Ricciardi,\u00a0Uri Hasson<\/p>\n\n\n\n<p class=\" eplus-wrapper\"><strong>DOI<\/strong>: 10.1111\/ejn.16459<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer eplus-wrapper\"><\/div>\n\n\n\n\t\n    \n        \n\t\t\t<a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1111\/ejn.16459\" target=\"_blank\" rel= \"noopener noreferrer nofollow\" class=\"button primary \">\n\n\t\t\t\t<span>\n\t\t\t\t\tREAD HERE\n\t\t\t\t<\/span>\n\n\t\t\t<\/a>\n\n        \n    \n","protected":false},"excerpt":{"rendered":"<p>article in journal: European Journal of Neuroscience, 2024<\/p>\n","protected":false},"featured_media":0,"template":"","research_type":[8],"research_team":[15],"class_list":["post-24966","research","type-research","status-publish","hentry","research_type-publications","research_team-computational-neuroscience"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.4 (Yoast SEO v27.4) -
