TABLE 6b.
Negative correlations between syllable rate and brain activity in the MON and ORA tasks in the PWS and CONT groups. Talairach coordinates are provided for regions where voxel clusters ( ≥ 10; p <.005) were significantly and negatively correlated with syllable rate following a conjunction analysis combining the effects of rate for MON and ORA tasks, calculated separately for the PWS and CONT groups. Local maxima coordinates shown with cluster size.
