Les présentations porteront sur les dernières avancées et d écouvertes en neuropsychologie\, en neurosciences cognitives et en neuro-i magerie. \n\nLes scientifiques du Neuro\, ainsi que des collègues et colla borateurs venus du milieu ou du monde entier\, se chargeront des conférenc es. Cette série se veut un forum virtuel pour les chercheurs et les stagia ires en vue de favoriser les échanges interdisciplinaires sur les mécanism es des troubles cérébraux et cognitifs\, leur diagnostic et leur traitemen t. \n\n\nPour assister en personne\, inscrivez-vous ici\n\nPour regarder v ia Vimeo\, cliquez ici\n\n\nAlberto Ara\n\nPostdoctoral Fellow\, The Neuro \, ´ó·¢²ÊƱƽ̨\n\nAbstract: Perception integrates both sensory input s and internal models of the environment. In the auditory domain\, predict ions play a critical role because of the temporal nature of sounds. Howeve r\, the precise contribution of cortical and subcortical structures in the se processes and their interaction remain unclear. It is also unclear whet her these brain interactions are specific to abstract rules or if they als o underlie the predictive coding of local features. We used high-field 7T functional magnetic resonance imaging to investigate interactions between cortical and subcortical areas during auditory predictive processing. Volu nteers listened to tone sequences in an oddball paradigm where the predict ability of the deviant was manipulated. Perturbations in periodicity were also introduced to test the specificity of the response. Results indicate that both cortical and subcortical auditory structures encode high-order p redictive dynamics\, with the effect of predictability being strongest in the auditory cortex. These predictive dynamics were best explained by mode ling a top–down information flow\, in contrast to unpredicted responses. N o error signals were observed to deviations of periodicity\, suggesting th at these responses are specific to abstract rule violations. Our results s upport the idea that the high-order predictive dynamics observed in subcor tical areas propagate from the auditory cortex.\n DTSTART:20241021T170000Z DTEND:20241021T180000Z LOCATION:De Grandpre Communications Centre\, Montreal Neurological Institut e\, CA\, QC\, Montreal\, H3A 2B4\, 3801 rue University SUMMARY:Feindel Brain and Mind Seminar Series: Cortical–Subcortical Interac tions Underlie Processing of Auditory Predictions Measured With 7T fMRI URL:/neuro/fr/channels/event/feindel-brain-and-mind-se minar-series-cortical-subcortical-interactions-underlie-processing-auditor y-359979 END:VEVENT END:VCALENDAR
