I have just rediscovered by old surface coloring function from the 2003 version of the Brede Toolbox. It can color a surface according to hull level. Here it is with a modified cortical surface representation provided by Heather Drury and David Van Essen.

Matlab code with the Brede Toolbox:

S = brede_sur_drury;
color = brede_sur_color(S, 'style', 'rgb');figure, 
brede_ta3_frame, brede_ta3_sur(S, 'color', color);

and then followed by

Wethaired, I never seem to get large values from the Emotiv quality signal.
