In Experiment 1, rats with posterior lateral olfactory tract/anterior amygdala lesions or with control neocortical lesions were tested for retention of a preoperatively learned odor detection task and for learning on new odor discrimination problems. All rats had perfect or near-perfect retention of the detection task, and there were no discernible differences between groups in learning on the new odor discrimination problems. In Experiment 2, an intensity-difference threshold for olfaction was determined in 4 rats before and after lesions of the posterior lateral olfactory tract and anterior amygdala. There were no apparent differences between pre- and postoperative performances on this psychophysical test. These results indicate that lateral olfactory tract projections to the amygdala and posterior olfactory cortex are not essential for normal performance on simple olfactory discrimination tasks.
在实验1中，对后侧嗅束/前杏仁核损伤的大鼠或对照新皮质损伤的大鼠进行测试，以检测其术前习得的气味检测任务的记忆保持情况以及对新的气味辨别问题的学习能力。所有大鼠对检测任务都有完美或近乎完美的记忆保持，并且在新的气味辨别问题学习上，各组之间没有明显差异。在实验2中，在4只大鼠的后侧嗅束和前杏仁核损伤前后测定嗅觉的强度差异阈值。在这项心理物理学测试中，术前和术后的表现没有明显差异。这些结果表明，向杏仁核和后嗅皮质的外侧嗅束投射对于简单嗅觉辨别任务的正常表现并非必不可少。
