The Neural Basis of Disgust Processing

Disgust is an emotion which elicited by offensive or repulsive object.Disgust can be divided into different types according to stimulus types.Insula and basal ganglia are the main brain structures of disgust processing.Moreover,anterior cingulate cortex,amygdala,hypothalamus,and medial prefrontal cortex are also involved in disgust processing.By summarizing the existed researches,we found that different types of disgust,and different sense modalities of disgust may have different neural basises.Future research should focus on the cognitive mechanism and neural basis of disgust processing,and the neurotransmitter related to disgust.
