<p><b>Regions of interest involved in the brain processing of itch significantly impacted by scratching.</b> Brain areas correlated with itch relief and scratching pleasurability are shown. The highest Z scores > 2.3 are presented for most significantly correlated clusters. *Deactivated in a higher-level contrast analysis in comparison to itch condition. <sup><b><i>#</i></b></sup> Results of regression analyses performed for active scratching an itch are displayed. BA = Brodmann area; ACC = anterior cingulate cortex; PCC = posterior cingulate cortex; VTA = ventral tegmental area; PAG = periaqueductal gray; VPL= ventral posterolateral nucleus; VPM = ventral posteromedial nucleus; AN = anterior nucleus; LON = lateral posterior nucleus; LDN = lateral dorsal nucleus; MD = mediodorsal nucleus.</p> <p>(DOCX)</p>
