Although the premotor cortex is considered central to body ownership in first-person full\u2013body illusions, the occipitotemporal cortex\u2014including the temporoparietal junction (TPJ) and the extrastriate body area (EBA)\u2014also plays a critical role in third-person full\u2013body illusions. However, their distinct contributions to the full-body illusion remain unclear, partly due to the challenges of applying neuroimaging in such experiments. This study employed functional near-infrared spectroscopy to investigate brain activity during a third-person full\u2013body illusion in virtual reality. Eighteen healthy human adult males participated in the study. The experiment consisted of two sessions. In Session 1, participants observed an avatar's back receiving either synchronous or asynchronous visual\u2013tactile stimulation. In Session 2, visual stimuli alone were presented to participants after they experienced the full-body illusion to induce visuotactile discrepancies. In the synchronous condition of Session 1, we found significant deactivation in the superior and middle temporal gyri (partially including the TPJ), followed by higher activity than in the asynchronous condition in the left middle occipital gyrus (likely EBA). The left premotor cortex also showed significant activation (uncorrected), although this did not survive multiple-comparison adjustment. In Session 2, the visuotactile discrepancy induced significant left premotor activation only in the synchronous condition (FDR-corrected). These findings suggest that the occipitotemporal cortex supports receptivity to third-person full\u2013body illusions, whereas the premotor cortex contributes to maintaining illusory body ownership by reconciling multisensory conflicts.<\/jats:p>","DOI":"10.1523\/eneuro.0587-24.2025","type":"journal-article","created":{"date-parts":[[2025,9,12]],"date-time":"2025-09-12T17:50:16Z","timestamp":1757699416000},"page":"ENEURO.0587-24.2025","update-policy":"https:\/\/doi.org\/10.1523\/eneuro.crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Distinct Roles of the Premotor and Occipitotemporal Cortices in the Full-Body Illusion"],"prefix":"10.1523","volume":"12","author":[{"given":"Katsuki","family":"Higo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Itsuki","family":"Ohtsuka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sotaro","family":"Shimada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"393","published-online":{"date-parts":[[2025,9,12]]},"reference":[{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-021-06211-8"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1492-22.2023"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.3","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1016\/S1364-6613(00)01501-1","article-title":"Social perception from visual cues: role of the STS region","volume":"4","author":"Allison","year":"2000","journal-title":"Trend Cogn Sci"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2013.01.029"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.5","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0745-06.2006"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.6","doi-asserted-by":"publisher","DOI":"10.1093\/biostatistics\/kxj037"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.7","doi-asserted-by":"publisher","DOI":"10.1038\/419269a"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.8","doi-asserted-by":"publisher","DOI":"10.1007\/s10548-010-0138-x"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.9","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2015.09.029"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.10","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2660-12.2012"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.11","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2014.04.067"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.12","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2023.105351"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.13","doi-asserted-by":"publisher","DOI":"10.1126\/science.1063414"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.14","doi-asserted-by":"publisher","DOI":"10.1126\/science.1142175"},{"key":"2025092910500969000_12.9.ENEURO.0587-24.2025.15","doi-asserted-by":"crossref","unstructured":"Ehrsson HH (2012) The concept of body ownership and its relation to multisensory integration.
