Stereotaxic lesions in either or both amygdala did not impair verbal learning ability (presented by ear as a paired-associates test). Centre median lesions alone did not impair this form of learning; however, when combined with a left amygdala lesion a significant decrease in scores occurred which persisted for up to two years after operation. The data support a hypothesis that medial thalamic structures have alerting functions in learning mechanisms.
单侧或双侧杏仁核的立体定向损伤并未损害言语学习能力(通过听觉呈现配对联想测试)。单独的中央中核损伤并未损害这种学习形式;然而,当与左侧杏仁核损伤相结合时,分数显著下降,且术后持续长达两年。这些数据支持了一个假说,即丘脑内侧结构在学习机制中具有警觉功能。
