We therefore compared the accordance of those techniques in healthy subjects using exactly the same tasks in both investigations. 19 healthy right-handed subjects performed object naming, pseudoword reading, verb generation, and action naming during fMRI at 3 T and rTMS. For rTMS language mapping, we stimulated 46 cortical spots over the left hemisphere; each site was stimulated for three times. Language positive points during rTMS for one, two, or three errors out the three stimulations per spot (1/3, 2/3, 3/3) were exported via DICOM, and compared to the positive fMRI clusters. As a result of this comparison, the best correlation was observed between 3/3 errors and fMRI for pseudoword reading and verb generation with t-values of pu &lt; 0.001, uncorrected for multiple comparisons, on average across the whole rTMS-spot map. We found a close spatial agreement between several rTMS-spots (2/3 and 3/3 errors) and fMRI clusters accentuated in the frontal lobe, followed by the parietal lobe and less in the temporal lobe. Compared to the fMRI clusters, there was a higher congruence for 2/3 and 3/3 errors than for 1/3 errors. Overall, results of language mapping in healthy subjects by fMRI and rTMS correspond well yet depending on the used language task.<br/> </p><p>PMID: 29981018 [PubMed - as supplied by publisher]</p> en-us Copyright 2000-2026 NITRC OSI Sun, 26 Apr 2026 7:55:38 GMT http://blogs.law.harvard.edu/tech/rss NITRC RSS generator
