Thalamic nuclei of the mammalian auditory system exhibit remarkable parallelism in their anatomical pathways and the patterns of synaptic signalling. This has led to the theory that lemniscal, or core thalamocortical projection, carries tonotopically organized and auditory specific information whereas the nonlemniscal thalamocortical pathway forms part of an integrative system that plays an important role in polysensory integration, temporal pattern recognition, and certain forms of learning. Recent experimental evidence derived from molecular, cellular and behavioural studies indeed supports the conjecture that lemniscal and nonlemniscal pathways are involved in distinctive auditory functions.
哺乳动物听觉系统的丘脑核在其解剖学通路和突触信号模式上表现出显著的平行性。这导致了一种理论，即lemniscal（或核心丘脑皮质投射）携带音调拓扑组织化的听觉特定信息，而非lemniscal丘脑皮质通路则构成了一个整合系统的一部分，该系统在多感觉整合、时间模式识别和某些形式的学习中发挥重要作用。最近来自分子、细胞和行为研究的实验证据确实支持了lemniscal和非lemniscal通路参与不同听觉功能的推测。
