Understanding taste (gustatory) – how the five senses work
From the book – Chapter 19: How Five Senses Actually Work
Taste (gustatory)
How it works
-
Food chemicals dissolve in saliva.
-
Taste buds detect five basic tastes: sweet, sour, salty, bitter, umami (savory).
-
Taste receptor cells send signals via cranial nerves.
-
Signals travel to the brainstem, then the thalamus.
-
Insula and frontal operculum process taste information.
Key structures: taste buds; cranial nerves (facial, glossopharyngeal, vagus); insula; frontal operculum.
Mental health connection
-
Taste changes are common in depression (food seems tasteless).
-
Eating disorders involve altered taste perception and reward processing.
-
Medications can cause taste disturbances affecting nutrition.
-
Comfort foods activate reward pathways (dopamine release).
