Taste perception in patients with insular cortex lesions

Studies have shown that 8% of neurons in the orbitofrontal cortex respond to taste stimuli, and a part of these neurons are finely tuned to particular taste stimuli. It has also been shown in monkeys that the responses of orbitofrontal neurons to taste decreased when the monkey eats to satiety. Se mer The primary gustatory cortex is a brain structure responsible for the perception of taste. It consists of two substructures: the anterior insula on the insular lobe and the frontal operculum on the inferior frontal gyrus of … Se mer Chemosensory neurons are those that discriminate between tastant as well as between the presence or absence of a tastant. In these neurons, the responses to reinforced (stimulated by tastant) licks in rats were greater than to those for the unreinforced (not … Se mer Studies using the Gustatory cortex of the rat model have shown that GC neurons exhibit complex responses to changes in concentration of tastant. For one tastant, the same neuron might increase its firing rate whereas for another tastant, it may only be responsive to … Se mer Like the olfactory system, the taste system is defined by its specialized peripheral receptors and central pathways that relay and process taste information. Peripheral taste receptors are … Se mer There have been many studies done to observe the functionality of the primary gustatory cortex and associated structures with various chemical … Se mer GC chemosensory neurons exhibit concentration-dependent responses.

Nettet6. aug. 2015 · When these cells are activated, they send signals to an area of the brain called the insular cortex, also known as the gustatory cortex, which makes us conscious of the perception of taste. Taste buds can differentiate between the five basic tastes: salty, sweet, sour, bitter, and umami (a savory taste found in foods like mushrooms or steak). NettetThe organization of taste coding in insular cortex is widely debated. While early work has focused on whether taste quality is encoded via labeled line or ensemble mechanisms, …
