Figure 2

All six nuclei were readily identifiable in horizontal sections stained with cresyl violet. Three sensory nuclei of the trigeminal system are apparent within the same section; the principal sensory nucleus (PSN), and two parts of the spinal trigeminal nucleus - the oralis (SpVo) and the interpolaris (SpVi).

The motor nuclei are shown separately. MoVI motor nucleus of the abducens nerve. MoX motor nucleus of the vagus. MoXII motor nucleus of the hypoglossal. Scale bar is 500μm for all images.
