+ | <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 | ||
