Taste is one of the basic senses that helps us give character to our food. There is a signal pathway between the tongue and brain that is the main focus of the full version of this video. Watch it here:

On the full version of this video, we’ve looked at the aspects of taste: Gustation, somatosensation and olfaction. We chat about the pathways involved in each and mentioned that the sensations are combined and processed in the orbitofrontal cortex.
For gustation, we will see how taste is detected by taste buds on taste papillae in the oral cavity. We then look at how the facial nerve, glossopharyngeal nerve and vagus nerve work together to carry taste sensation to the rostral solitary nucleus in the brainstem. From there, signals are passed superiorly by 3 different pathways to terminate in the taste sensory cortex, amygdala and lateral hypothalamic area.
After that, we will discuss the somatosensory pathway, divided into its two parts: touch; and temperature and pain. Then, we go over olfaction and its pathway.
Finally, we mention dysgeusia, a condition where knowledge of the taste pathway may be relevant in discovering more understanding of what’s going on and for developing ways to help those afflicted.
