The gustatory cortex is the brain structure responsible for the perception of taste. It consists of the anterior insula on the insular lobe and the frontal operculum on the inferior frontal gyrus of the frontal lobe.Neurons in the gustatory cortex respond to the five main tastes.ntroduction [edit]. The Gustatory System or sense of taste allows us to perceive different flavors from substances like food, drinks, medicine etc. Molecules that we taste or tastants are sensed by cells in our mouth, which send information to the brain.
Taste Centers in the Brain As explained under Taste Buds, food and substances dissolved in the saliva enter the taste pores where it makes contact with the microvilli of the taste (gustatory cells). This then triggers a depolarization of the taste cell membrane, a subsequent release of neurotransmitters and stimulation of the surrounding nerve fibers. Signals from the nerve fibers of the taste buds travels via cranial nerves VII, IX and X to the tractus solitarius (gustatory area) located in the posterior brain stem. From here neurons transmit signals to the thalamus (ventral posterior medial nucleus).
