Schematic drawing of the vagal pain pathway. 1: Vagus nerve 2: Nucleus of the solitary tract in the medulla oblongata 3: Descending parasympathetic fibers at the level of C1–2 entering the dorsal horn of the spinal cord 4: Spinothalamic neurons exiting the spinal cord en route to the thalamus 5: Projections of the spinothalamic neurons to the centralis lateralis, centrum medianum parafascicularis and ventral posterolateral nuclei of the thalamus
