Visualisation of displacement vectors for each point on the surface, separately for (A) male and (B) female bipolar patients vs. controls. Left column: change in surface area coded as red [expanded in bipolar disorder relative to controls] or blue [contracted in bipolar disorder relative to controls]; data are coded as 33% percentiles, with darker colours indicating upper percentiles. Centre column: change in angle of displacement vector to surface normal coded as red [angled outward in bipolar disorder relative to controls] or blue [angled inward in bipolar disorder relative to controls]; darker colours code smaller angle to the normal, i.e. displacement vector more perpendicular to the surface. Right column: length of displacement vector, in any direction, coded as red; darker colour codes greater vector length, i.e. greater difference between bipolar disorder and controls.
