Parameters
----------
as_sphere : bool, optional
Return spheres instead of cortical surfaces. Default is False.
with_normals : bool, optional
Whether to compute surface normals. Default is True.
join : bool, optional
If False, return one surface for left and right hemispheres. Otherwise,
return a single surface as a combination of both left and right
surfaces. Default is False.
Returns
-------
surf : tuple of BSPolyData or BSPolyData
Surfaces for left and right hemispheres. If ``join == True``, one
surface with both hemispheres.
