Panel (a) displays topographic maps of EEG scalp potentials at different time windows (90-130 ms, 130-170 ms, and 170-210 ms) after stimulus onset, illustrating the distribution of electrical activity across the scalp. Panel (b) shows the arrangement of EEG electrodes, highlighting the region of interest for analysis, with the shaded area indicating electrodes likely used for measurement. Panel (c) presents event-related potentials (ERPs) for 'Letter' and 'Non-letter' conditions, depicting the average voltage change over time, with a clear divergence between the two conditions after approximately 130 ms. The negative deflection prominent in the 'Letter' condition suggests differential processing of visual stimuli categorized as letters compared to other visual forms. Panel (d) overlays functional activation maps from fMRI onto an axial brain slice, indicating significant brain regions involved in word processing. Specific areas of interest, such as the Visual Word Form Area (VWFA), are highlighted with schematic markers (blue triangle) along with a 'Letter area' (red circle), suggesting these regions are crucial for decoding written language. The overall analysis suggests a rapid and anatomically specific neural response to visual word recognition, evolving over time from early visual processing stages to more specialized cortical areas.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/brain-activity-in-visual-cortex-during-word-processing/195278/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/brain-activity-in-visual-cortex-during-word-processing/195278.png","ImageObject",442,249,{"name":42,"@type":43},"Dipper","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-09-25","2026-09-03",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What
