非人灵长类动物的听觉识别记忆不同于其他感觉系统的识别记忆。猴子学习规则的视觉和触觉延迟匹配到样品在几个会议，然后显示一个审判识别记忆持续10-20分钟，相比之下，猴子需要数百个会议，掌握规则的听觉识别，然后显示持续时间不超过30-40秒。此外，与鼻腔损伤对视觉记忆的严重影响不同，这种损伤对猴子的听觉记忆表现没有影响。听觉记忆的解剖学途径可能与视觉记忆不同。长期视觉识别记忆需要从视觉关联区TE与嗅周皮层（PRC）的区域35和36的解剖学连接。我们研究了是否有一个类似的听觉处理的解剖路径，或者说，听觉识别记忆差可能反映了缺乏这样的途径。我们的假设是，再认记忆的听觉通路起源于颞叶上级回（rSTG）的高级加工区，经颞极背外侧到达内侧颞叶的鼻皮质。为了测试这一点，我们将逆行（3% FB和2% DY）和顺行（10% BDA 10，000 mW）示踪剂注射在rSTG和颞极的背外侧区域38 DL。结果表明，38 DL区接受来自rSTG听觉联合区Ts 1、TAa、TPO、口侧副带的密集投射，以及少量来自Ts 2 -3和PGa区的投射。反过来，38 DL区密集地投射到PRC的35区、内嗅皮层（EC）和后海马旁皮层的TH/TF区。值得注意的是，这一预测避开了PRC 36 r/c区的大部分地区。这种解剖结构可能有助于我们理解恒河猴的听觉记忆力差。
Auditory recognition memory in non-human primates differs from recognition memory in other sensory systems. Monkeys learn the rule for visual and tactile delayed matching-to-sample within a few sessions, and then show one-trial recognition memory lasting 10–20 min. In contrast, monkeys require hundreds of sessions to master the rule for auditory recognition, and then show retention lasting no longer than 30–40 s. Moreover, unlike the severe effects of rhinal lesions on visual memory, such lesions have no effect on the monkeys' auditory memory performance. The anatomical pathways for auditory memory may differ from those in vision. Long-term visual recognition memory requires anatomical connections from the visual association area TE with areas 35 and 36 of the perirhinal cortex (PRC). We examined whether there is a similar anatomical route for auditory processing, or that poor auditory recognition memory may reflect the lack of such a pathway. Our hypothesis is that an auditory pathway for recognition memory originates in the higher order processing areas of the rostral superior temporal gyrus (rSTG), and then connects via the dorsolateral temporal pole to access the rhinal cortex of the medial temporal lobe. To test this, we placed retrograde (3% FB and 2% DY) and anterograde (10% BDA 10,000 mW) tracer injections in rSTG and the dorsolateral area 38DL of the temporal pole. Results showed that area 38DL receives dense projections from auditory association areas Ts1, TAa, TPO of the rSTG, from the rostral parabelt and, to a lesser extent, from areas Ts2-3 and PGa. In turn, area 38DL projects densely to area 35 of PRC, entorhinal cortex (EC), and to areas TH/TF of the posterior parahippocampal cortex. Significantly, this projection avoids most of area 36r/c of PRC. This anatomical arrangement may contribute to our understanding of the poor auditory memory of rhesus monkeys.
