  1. Localization in the x, y, z Talairach (Tal) and MNI coordinates (mm) of left and right dipoles, i.e., Dipole 1 located in the fusiform gyrus (FG) and Dipole 2 in the middle occipital gyrus (MOG), the time-interval for the dipole fit and the resulting residual variance (% RV) for the grand-averaged and for the individual ERP data are displayed for each face rotation condition. For the individual ERP data, we report the average time-intervals used for the dipole fit and the statistical mean of residual variance (+ 1 SEM) obtained for each face rotation condition. Note that Dipole 1's location remained stable as we restrained its location across rotation conditions, while relaxing that of Dipole 2.
