IQ = Intelligence Quotient. Sampling is indicated as either bilateral (bi), left (L), right (R), bilateral with right dominance (bi/r +), or bilateral with left dominance (bi/l +). Stimulation sites include the anterior cingulate cortex (ACC), the middle cingulate cortex (MCC), and the posterior cingulate cortex (PCC). Granger-in and -out values are expressed as unitless correlation coefficients and are assigned signal dominance of bilateral (bi), left (L), right (R), bilateral with left preference (bi pref L), or bilateral with right preference (bi pref R)
