研究了杏仁核基底外侧复合体（ABL）和中央核（CN）在味觉增强气味厌恶（TPOA）学习中的相对作用，这是一种依赖于两种感觉模式的信息加工的联想学习任务。在实验1中，对这些系统的神经毒性病变的大鼠进行TPOA任务的训练，采用复合味觉-气味条件刺激（CS），然后给予LiCl。结果表明，ABL损伤导致嗅觉厌恶学习功能受损，但对条件性味觉厌恶学习功能无影响。相比之下，神经网络受损的大鼠学会了这两项任务。实验2研究了ABL损伤对TPOA和气味识别学习的影响。气味辨别程序使用位置偏好任务来展示嗅觉信息的正常处理。结果表明，虽然abl损伤的动物在TPOA上受损，但在气味识别学习上没有缺陷。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Examined the relative contributions of the amygdaloid basolateral complex (ABL) and central nucleus (CN) to taste-potentiated odor aversion (TPOA) learning, an associative learning task that is dependent on information processing in 2 sensory modalities. In Exp 1, rats with neurotoxic lesions of these systems were trained on the TPOA task by presenting a compound taste–odor conditioned stimulus (CS), which was followed by LiCl administration. Results showed that ABL damage caused an impairment in potentiated odor aversion learning but no deficit in the conditioned taste aversion. In contrast, rats with CN damage learned both tasks. Exp 2 examined the effects of ABL damage on TPOA and odor discrimination learning. The odor discrimination procedure used a place preference task to demonstrate normal processing of olfactory information. Results indicated that although ABL-lesioned animals were impaired on TPOA, there was no deficit in odor discrimination learning.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
