Large-scale automated synthesis of human functional neuroimaging data
Yarkoni, Poldrack, Nichols, Van Essen and Wager, Nature Methods 8(8), 2011, 665-670. Automated text mining and coordinate extraction; database of 100,953 activation foci from 3,489 studies in 17 journals. Forward and reverse maps differ: for emotion, frontal regions consistent in the forward map but not selective in the reverse map, with amygdala and ventromedial prefrontal cortex more selective; for working memory the forward map highlighted dorsolateral prefrontal cortex, anterior insula and dorsal medial frontal cortex while the reverse map pointed to anterior prefrontal and posterior parietal cortex. Single-subject decoding of 281 maps (94 working memory, 108 emotion, 79 pain): sensitivities about 94, 70 and 65 per cent, chance 33 per cent. Across 25 frequent terms, mean pairwise accuracy about 72 per cent; closely related terms such as executive and working memory not separable above chance.
