Functional properties of a crossed spinocerebellar tract with cell bodies located in laminae VII and IX of the S1 segment were investigated using intracellular recording. The neurones were found to be excited by group I and II muscle afferents and afferents of skin, joint and interosseus nerves. Volleys from group II muscle afferents and cutaneous afferents evoked inhibition in these cells. It is concluded that S1 spinocerebellar neurones convey a similar type of information to that of dorsal spinocerebellar tract and ventral spinocerebellar tract neurones but integrate it in a different way.
利用细胞内记录法，对位于S1节段VII层和IX层、具有交叉脊髓小脑束的功能特性进行了研究。发现这些神经元受到I类和II类肌肉传入纤维以及皮肤、关节和骨间神经传入纤维的兴奋作用。来自II类肌肉传入纤维和皮肤传入纤维的冲动在这些细胞中引起抑制作用。得出的结论是，S1脊髓小脑神经元传递的信息类型与背侧脊髓小脑束和腹侧脊髓小脑束神经元的相似，但整合方式不同。
