All coordinates are described according to the Montreal Neurological Institute system, and were obtained through a conjunction analysis of data from ScaleImprov and JazzImprov. Abbreviations: p. triangularis, pars triangularis; p. opercularis, pars opercularis; PMC, premotor cortex; SMA, supplementary motor area; STG, superior temporal gyrus; MTG, middle temporal gyrus; STS, superior temporal sulcus; ITG, inferior temporal gyrus; SMG, supramarginal gyrus; IPS, intraparietal sulcus; SPL, superior parietal lobule; OG, occipital gyrus; ACC, anterior cingulate commissure
