In brain sections stained with monoclonal antibody SMI-32, which recognizes non-phosphorylated neurofilament protein, we distinguished separate caudal, intermediate, and rostral subdivisions of gigantocellular precentral cortex (areas 4c, 4i, and 4r) in macaque monkeys. The divisions form bands extending mediolaterally across the major body-region representations of the primary motor cortex (M1). These observations provide additional evidence that primary motor cortex is not a single, structurally homogeneous cortical area.
在用识别非磷酸化神经丝蛋白的单克隆抗体SMI-32染色的脑切片中，我们在猕猴的巨细胞中央前皮层（4c区、4i区和4r区）区分出了单独的尾侧、中间和嘴侧亚区。这些分区形成了横跨初级运动皮层（M1）主要身体区域表征、从内侧向外侧延伸的条带。这些观察结果提供了额外的证据，表明初级运动皮层不是一个单一的、结构上均匀的皮层区域。
