Brain regions identified by analysis of UNCUED trials

Brain Region	Side	Center of Mass (mm) X, Y, Z	Brodmann Area(s)	Volume (µl)
Anterior cingulate gyrus	B	1.8, 41.2, 13.2	24, 32	5427
Posterior cingulate gyrus	B	−0.2, −43.6, 29.3	23,31,30	2131
Angular gyrus/STG	L	−47.4, −64.5, 31.1	39	541

Regions in Talairach space where the BOLD signal intensity increased linearly with $\frac{1}{{\mathit{RT}}_i}$, i.e. with faster responding, on a trial-by-trial basis. B = bilateral, L = left.
