Nettet10. sep. 2015 · As a consequence animals later avoid this taste, a reaction known as conditioned taste aversion (CTA). An established CTA extinguishes over time when the CS is repeatedly presented in the absence of the US. However, inter-individual differences in CTA extinction do exist. 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.
