根据逆向激活技术确定的丘脑区域，麻醉猴 [Macaca fasciculis] 的腰骶脊髓丘脑神经元被分为内侧 (M-STT)、外侧 (L-STT) 或外侧内侧 (LM-STT) 脊髓丘脑束细胞。 M-STT 细胞仅投射到内侧丘脑（中央外侧核或内侧背核的邻近部分），L-STT 细胞仅投射到外侧丘脑（腹侧后外侧核），LM-STT 细胞投射到外侧和内侧丘脑核。讨论了反应特征和电生理学。 M-STT 细胞的大兴奋性感受野可能依赖于涉及激活网状结构神经元的上升束的神经通路。
On the basis of the thalamic area to which they project as determined with the antidromic activation technique, lumbosacral spinothalamic neurons in anesthetized monkeys [Macaca fascicularis] were classified as medial (M-STT), lateral (L-STT), or lateral-medial (LM-STT) spinothalamic tract cells. M-STT cells projected only to the medial thalamus (central lateral nucleus or adjacent parts of the medial dorsal nucleus), L-STT cells projected only to the lateral thalamus (ventral posterior lateral nucleus) and LM-STT cells projected to both lateral and medial thalamic nuclei. Response characteristics and electrophysiology are discussed. Large excitatory receptive fields of M-STT cells may depend on a neural pathway involving ascending tracts that activate neurons of the reticular formation.
