Analysis was repeated for 333 Gordon parcels. Data for each parcel was not averaged across the hemispheres, nor was it filtered for significance or positivity.
Sub-cortical data
MID activation was investigated for 30 sub-cortical structures based on FreeSurfer sub-cortical parcellations (check!).
Covariates
Scanner: In order to control for variance due to site (for which specific information not available), we included the variable "device serial number" which indicates the individual MR scanners used to acquire data. In this dataset there were 27 separate devices included, however two had no data leaving 25 separate scanners. The number of subjects acquired per scanner varied from a minimum of 9 to a maximum of 283 (see Figure \ref{191427}).
