Deep, lumbar, spinothalamic tract cells have fine distal dendrites which project to, and receive synaptic connections within, the ventral (VF) and/or lateral funiculi (LF). The projection to the LF is inversely related (P less than 0.05) to the projection of the VF. It is proposed that the white matter dendrites receive a particular level of tonic, excitatory drive from a wide variety of axons in the VF and/or LF and that this drive is responsible for the spontaneous activity seen in these cells; activity which provides a baseline against which particular forms of natural stimulation may be registered either by causing an increase or a decrease in the firing frequency.
深层腰段脊髓丘脑束细胞具有细小的远端树突，这些树突投射到腹侧（VF）和/或外侧索（LF）并在其中接受突触连接。向LF的投射与VF的投射呈负相关（P小于0.05）。有人提出，白质树突从VF和/或LF中的多种轴突接收特定水平的紧张性兴奋性驱动，并且这种驱动负责这些细胞中所见的自发活动；这种活动提供了一个基线，通过引起放电频率的增加或减少，可以记录特定形式的自然刺激。
