Behavioral, ethological, and electrophysiological evidence suggests that the highly unpleasant, bitter taste of a concentrated quinine hydrochloride (QHCL) should activate the human amygdala. In the present study, healthy subjects tasted 0.02 M QHCL or water while regional cerebral blood flow (rCBF) was assayed with H(2)(15)O PET. Subjects were also studied while tasting a pleasant sucrose solution and resting with eyes closed (ECR). Tasting QHCL significantly increased rCBF within the left… 

Figures and Tables from this paper

Ventromedial prefrontal cortex response to concentrated sucrose reflects liking rather than sweet quality coding.
Greater response was observed in the ventromedial prefrontal cortex (vmPFC) to the sucrose when it was rated pleasant versus neutral compared with unpleasant versus neutral, suggesting that response in the vmPFC underlies sweet-taste preference and this region is preferentially sensitive to affectively positive tastes.
Neural correlates of evaluative compared with passive tasting
Functional magnetic resonance imaging findings show that neural encoding of taste varies as a function of task beyond that of the initial cortical representation.
Opposing neural effects of naltrexone on food reward and aversion: implications for the treatment of obesity
Findings suggest that modulation of key brain areas involved in reward processing, cognitive control and habit formation such as the dorsal anterior cingulate cortex and caudate might underlie reduction in food intake with opioid antagonism.

Mouth rinsing and ingestion of a bitter-tasting solution increases corticomotor excitability in male competitive cyclists
It is concluded that the activation of bitter taste receptors in the oral cavity and upper gastrointestinal tract has the capacity to increase corticomotor excitability in male competitive cyclists.
Effects of pramipexole on the processing of rewarding and aversive taste stimuli
The results are consistent with an ability of acute, low-dose pramipexole to diminish dopamine-mediated responses to both rewarding and aversive taste stimuli and could also play a role in its proposed efficacy in treatment-resistant depression.

The D2 antagonist sulpiride modulates the neural processing of both rewarding and aversive stimuli in healthy volunteers
These results suggest that acute dopamine receptor blockade modulates mesolimbic and mesocortical neural activations in response to both rewarding and aversive stimuli in healthy volunteers.


Representation of pleasant and aversive taste in the human brain.
It is concluded that the orbitofrontal cortex is involved in processing tastes that have both positive and negative affective valence and that different areas of the orbit ofrontal cortex may be activated by pleasant and unpleasant tastes.
Aversive gustatory stimulation activates limbic circuits in humans.
The present results indicate that the amygdala and orbitofrontal cortex respond to aversive stimuli in both the olfactory and gustatory modalities, and highlight the role of the pregenual cingulate in negative emotional processing.
Changes in brain activity related to eating chocolate: from pleasure to aversion.
The hypothesis that there are two separate motivational systems: one orchestrating approach and another avoidance behaviours is supported, suggesting that the reward value of food is represented here.
Gustatory neural coding in the amygdala of the alert macaque monkey.
Neurons in the amygdala are implicated in mediating hedonic appreciation, emotional expression, and conditioning, particularly as these relate to feeding, and there was no strong evidence for gustatory neuron types, nor were functionally similar cells located together in a chemotopic arrangement.

Evidence is provided that the human amygdala participates in the hedonic or emotional processing of olfactory stimuli and the activity within the left amygdala was associated significantly with subjective ratings of perceived aversiveness.
Gustatory responses in the frontal opercular cortex of the alert cynomolgus monkey.
It was concluded that most taste cells may be assigned to a small number of groups, each of which is statistically independent of the others, but within which the constituent neurons are not identical.

Studies on gustatory responses of amygdaloid neurons in rats
Across-neuron correlations between magnitudes of responses to pairs of the four basic taste stimuli have suggested a tendency that taste information is processed in a hedonic dimension in the amygdala.
A Role for the Right Anterior Temporal Lobe in Taste Quality Recognition
Results suggest that although taste sensation may be computed in the primary taste cortex, recognition requires further processing by structures located in the anteromedial temporal lobe, and point to preferential processing of this higher-order gustatory function by the right cerebral hemisphere.
