Axonal projections from the forelimb representation of the rat primary somatosensory cortex (case R605)

Bright-field microscopy images of serial coronal brain sections showing anterogradely labeled axons in an adult male Sprague Dawley rat following injection of Phaseolus vulgaris leucoagglutinin in the forelimb representation of the primary somatosensory cortex. The labeling was visualized histologically in sections counterstained to visualize cytoarchitecture. The presence of cytochrome oxidase positive barrels has been visualized in selected sections through the sensorimotor cortex.

本数据集包含成年雄性斯普拉格-道利大鼠（Sprague Dawley rat）的连续冠状脑切片的明场显微镜成像，成像显示了顺行标记的轴突——实验中向该大鼠初级躯体感觉皮层（primary somatosensory cortex）的前肢代表区注射了菜豆血凝素（Phaseolus vulgaris leucoagglutinin）。标记物通过组织学方法实现可视化，切片经复染以呈现细胞构筑（cytoarchitecture）。部分覆盖感觉运动皮层（sensorimotor cortex）的切片中，可观测到细胞色素氧化酶阳性桶状结构（cytochrome oxidase positive barrels）。
