The Insular Taste Cortex Contributes to Odor Quality Coding
Despite distinct peripheral and central pathways, stimulation of both the olfactory and the gustatory systems may give rise to the sensation of sweetness. Whether there is a common central mechanism producing sweet quality sensations or two discrete mechanisms associated independently with gustatory and olfactory stimuli is currently unknown. Here we used fMRI to determine whether odor sweetnes...
متن کاملGustatory insular cortex, aversive taste memory and taste neophobia.
Prior research indicates a role for the gustatory insular cortex (GC) in taste neophobia. Rats with lesions of the GC show much weaker avoidance to a novel and potentially dangerous taste than do neurologically intact animals. The current study used the retention of conditioned taste aversion (CTA) as a tool to determine whether the GC modulates neophobia by processing taste novelty or taste da...
متن کاملThe anterior insular cortex represents breaches of taste identity expectation.
Despite the importance of breaches of taste identity expectation for survival, its neural correlate is unknown. We used fMRI in 16 women to examine brain response to expected and unexpected receipt of sweet taste and tasteless/odorless solutions. During expected trials (70%), subjects heard "sweet" or "tasteless" and received the liquid indicated by the cue. During unexpected trials (30%), subj...
متن کاملConditioned taste aversion and latent inhibition following extensive taste preexposure in rats with insular cortex lesions.
Lesions of the insular cortex (IC) attenuate acquisition of conditioned taste aversions (CTAs). We have suggested that this impairment is the expected consequence of a failure of IC-lesioned (ICX) rats to recognize unfamiliar taste stimuli as novel. That is, ICX rats treat novel taste stimuli as if they are familiar and as a result show a latent inhibition-like retardation of learning. This acc...
متن کاملNeuronal representations of stimuli in the mouth: the primate insular taste cortex, orbitofrontal cortex and amygdala.
The responses of 3687 neurons in the macaque primary taste cortex in the insula/frontal operculum, orbitofrontal cortex (OFC) and amygdala to oral sensory stimuli reveals principles of representation in these areas. Information about the taste, texture of what is in the mouth (viscosity, fat texture and grittiness, which reflect somatosensory inputs), temperature and capsaicin is represented in...
