Using a matched task design and functional magnetic resonance imaging–based decoding, we systematically compared the localization of object-identity representations during perception and VWM. A robust dissociation emerged: Perception kept object information largely contralateral, whereas VWM produced robust ipsilateral representation even when memorizing bilateral items. These expanded representations exploited more than 90% of ipsilateral OSC vertices and could not be attributed to increased attentional span. Critically, the ipsilateral representations closely mirrored contralateral representations, implicating interhemispheric coordination in VWM. Together, these findings demonstrate that object VWM flexibly recruits distributed high-level visual cortex, with spatial reorganization distinguishing mnemonic flexibility from perceptual fidelity.</div>","PeriodicalId":21609,"journal":{"name":"Science Advances","volume":"12 19","pages":""},"PeriodicalIF":12.5,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147830237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We address this question using a compelling visual illusion (perceptual filling-in) that isolates neural processes underlying transitions from veridical to illusory conscious experience. Using whole-brain magnetoencephalographic imaging and rapid invisible frequency tagging, we tracked cortical dynamics during filling-in and assessed their modulation by microsaccadic eye movements, which are known to delay the illusion. We found that transitions in conscious perception involved two dissociable mechanisms: (i) boundary fading in visual cortex, reflected by increased excitability and reduced alpha-band activity, consistent with a shift in excitation-inhibition balance, and (ii) higher-order perceptual monitoring processes involving motor cortex, indexed by decreased high-alpha and beta-band activity. Microsaccades selectively reset both processes.
