 Data analysis: Standard fMRI analysis will be analyzed using established fMRI software. Statistical parametric analysis will be performed to generate activation maps. fMRI data will be corrected for multiple comparisons using a false discovery rate q 0.05 and threshold for cluster values to conservatively control for type I error. Behavioral data will be analyzed with paired t-test and ANOVA calculations used for group comparison with p 0.05 with Bonferroni correction considered statistically significant.
