Abstract

In China, the rate of spicy food consumption is rising, and chili pepper is among the most popular spicy foods consumed nationwide. Therefore, investigation into spicy food craving is of public health interest and can also provide better insights into the mechanisms that underlie food cravings more generally. This exploratory study aimed to determine neural circuits underlying spicy food craving by comparing brain response to the cues of foods containing chili peppers in extreme cravers and non-cravers defined by scores on the Spicy Food Craving Questionnaire. A group of extreme cravers (n = 25) and a group of age- and sex-matched non-cravers (n = 26) participated in an fMRI event-related cue-reactivity paradigm, during which pictures of foods with visible chili peppers and pictures of foods with no chili peppers were presented. Results showed that extreme spicy food cravers exhibited increased activation in bilateral insula, left putamen, left dorsal anterior cingulate cortex, right inferior parietal lobule, right lingual gyrus, bilateral cuneus, left precuneus, left fusiform gyrus, and right precentral gyrus compared to non-cravers when exposed to the cues of foods containing chili versus foods without chili. While we did not...Continue Reading

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.
