Table 4. MNI coordinates and t-values of the local maxima from the conjunction of the balance and calculation contrasts.
Cluster size is given for the peak voxel per cluster. Voxel size is 3x3x3 mm. P-values for the age (young, old) by condition (balance, calculation, dual-task) interactions are given, with and without Bonferonni correction.
