脊髓背角通过背柱的侧支接受来自无害初级传入神经元的传入输入。这种输入主要由板层III-VI中的神经元整合和中继。编码无害输入的背角神经元通过背柱和背外侧索投射到延髓和颈髓。伤害性初级传入神经元从Lissauer束经侧支进入脊髓背角。伤害性输入由I、II和V层的神经元整合和中继，这些神经元通过前外侧束投射到网状结构和丘脑。
The dorsal horn of the spinal cord receives afferent input from innocuous primary afferent neurons via collaterals from the dorsal columns. This input is integrated and relayed primarily by neurons in laminae III-VI. Dorsal horn neurons which encode innocuous inputs project to the medulla and the cervical spinal cord via the dorsal columns and the dorsolateral funiculus. Nociceptive primary afferent neurons enter the spinal dorsal horn via collaterals from Lissauer’s tract. Nociceptive input is integrated and relayed by neurons in laminae I, II and V which project to the reticular formation and thalamus via the anterolateral tract.
