Studies using permanent lesions implicate the amygdala, a recipient of gustatory and viscerosensory information, in taste aversion learning. Reviewing this literature with respect to the location of the lesions and the quality of the behavioral methodology reveals little, if any, involvement of the medial amygdala or central nucleus in conditioned taste aversion. Although a disruption is found following damage to the basolateral region, the attenuated conditioned taste aversion appears to be a consequence of a lesion-induced impairment of neophobia rather than an association formation deficit. The key to understanding the functional significance of the basolateral amygdala in conditioned taste aversion reduces, we believe, to determining the role of this structure in gustatory neophobia.
使用永久性损伤进行的研究表明，味觉厌恶学习涉及杏仁核，它是味觉和内脏感觉信息的接收者。就损伤的位置和行为方法的质量来审视这一文献发现，内侧杏仁核或中央核在条件性味觉厌恶中几乎没有（如果有的话）参与。尽管在基底外侧区域受损后发现有功能破坏，但条件性味觉厌恶减弱似乎是损伤引起的新恐惧症受损的结果，而非联想形成缺陷。我们认为，理解基底外侧杏仁核在条件性味觉厌恶中的功能意义的关键在于确定该结构在味觉新恐惧症中的作用。
