From: The Influence of verbalization on the pattern of cortical activation during mental arithmetic
ROI analysis results: Rolandic Operculum. Significant correlations between peak activations in the Rolandic operculum and the self-reported use of verbalization: In the first functional session a significant correlation appeared for the subtraction problems and the left Rolandic Operculum. In the second functional session significant correlations appeared for multiplications presented with written number words and the right and left [* correlation passes the Bonferroni correction (critical p value is .006)] Rolandic Operculum, and for multiplications presented with Arabic numerals and the left Rolandic Operculum.
