WebCentral Processing of Taste Information. The sensory pathway for gustation travels along the facial, glossopharyngeal and vagus cranial nerves, which synapse with neurons of the solitary nucleus in the brain stem. Axons from the solitary nucleus then project to the ventral posterior nucleus of the thalamus. Finally, axons from the ventral posterior nucleus … WebVia multineuronal pathways, it activates specific parasympathetic pathways arising from the ciliary ganglion. This pathway causes the ciliary muscle to contract, thereby reducing tension on the lens and allowing it to become more rounded so the image of the near object can be focused on the central part of the retina.
