(Inferior parietal lobule - Supramarginal gyrus)

Associated Functions
Reviewer's note

The supramarginal gyrus of the left hemisphere appears to support some complex linguistic processes, such as semantic processing and verbal creativity. Its role in spatial knowledge, and particularly, controlling movements guided by visuospatial information seems evident. Its role in calculation is probably related with its adjacency to the angular gyrus and intraparietal sulcus. The left supramarginal gyrus seems to be involved in some complex motor activity, such as motor planning; this function is continued in the superior parietal lobe. BA40 also participates in an executive function network, involved in tasks such as deductive reasoning and performing creative tasks
