Regions observed during saccade response (correct trials only) that showed significant interaction effects

Talairach Coordinates			Region	BA	Effect	F	P	Volume (mL)
x	y	z
−25	44	−4	Left middle frontal gyrus, lateral OFC**	11	A × T	4.44	0.006	378
2	23	26	Right cingulate gyrus**	24	I × T	3.99	0.010	837
−1	11	35	Left cingulate gyrus*	24, 32	A × I × T	2.86	0.037	891

Note: Single asterisk indicates that interaction is across 13 estimated time points, double asterisks indicate that interaction is across TRs 3–6. Abbreviations: A × T = age by time interaction, I × T = incentive by time interaction.
