If you choose Scripting/Templates/fmri_mesh menu item you get something that is close. You would want to use the 'Toon' cel shader and set the mesh color to green. With these changes the script becomes:

import gl
gl.resetdefaults()
gl.meshload('BrainMesh_ICBM152.rh.mz3')
gl.overlayload('motor_4t95mesh.rh.mz3')
gl.overlaycolorname(1, 'red')
gl.shaderxray(1.0, 0.3)
gl.azimuthelevation(110, 15)
gl.meshcurv()
gl.meshcolor(128,192,128)
gl.shadername('Toon')
