[Eeglablist] Children's skull thickness

[Ryan Lycca]

Hi,
 
When I used the spherical head model for the child subjects to do some calculation, what specific radii of the scalp, the skull and cortex should I use? I mean, usually the radii of 1.0, 0.92 and 0.87 are used in the 3-sphere head model for the adults, but is there any reference giving the radii of the children? The straightforward way is probably to estimate the radii from the subjects' MRI. But it seems to take too much effort. 
Any suggestion? Many thanks.
 
Ryan
