 +  <a href=/​reference/​ft_headmodel_concentricspheres><​font color=green>​FT_HEADMODEL_CONCENTRICSPHERES</​font></​a>​ creates a volume conduction model
 +  of the head based on three or four concentric spheres. For a 3-sphere
 +  model the spheres represent the skin surface, the outside of the
 +  skull and the inside of the skull For a 4-sphere model, the surfaces
 +  describe the skin, the outside-skull,​ the inside-skull and the inside of the
 +  cerebro-spinal fluid (CSF) boundaries.
 + 
 +  The innermost surface is sometimes also referred to as the brain
 +  surface, i.e. as the outside of the brain volume.
 + 
 +  This function takes as input a single headshape described with
 +  points and fits the spheres to this surface. If you have a set of
 +  points describing each surface, then this function fits the spheres
 +  to all individual surfaces.
 + 
 +  Use as
 +    headmodel = ft_headmodel_concentricspheres(mesh,​ ...)
 + 
 +  Optional input arguments should be specified in key-value pairs and can
 +  include
 +    conductivity = vector with the conductivity of each compartment
 +    fitind ​      = vector with indices of the surfaces to use in fitting the center of the spheres
