There are numerous reports of enhanced or emerged visual arts abilities in patients with semantic impairment. These led to the theory that a loss function on language side brain can result changes ability draw and/or paint. Further, left posterior middle temporal gyrus (l-pMTG) has been revealed contribute higher control mechanisms objects recognition and integration information, within widely distributed network hemisphere. Nevertheless, not fully studied neural bases. The aim this study is examine role l-pMTG shape its reconstruction drawing behavior, by using combining method repetitive transcranial magnetic stimulation (rTMS) functional near-infrared spectroscopy (fNIRS). Eighteen healthy participants received low frequency inhibitory rTMS their during task Benton Visual Retention Test (BVRT). was significant decrease mean accuracy reproductions Complex designs BVRT, compared Simple Medium designs. fNIRS data showed strong negative correlations results BVRT. Though our hypothesis had contradiction would have inhibited activity stimulated site, suggest such as BVRT require activations l-TL well l-pMTG.
