Axonal projections from the D3 whisker representation of the rat primary somatosensory cortex (case R604)

Bright-field microscopy images of serial coronal brain sections showing anterogradely labeled axons in an adult male Sprague Dawley rat following injection of biotinylated dextran amine in the D3 whisker 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（Sprague Dawley）大鼠的连续冠状脑切片的明场显微镜图像：该大鼠的初级躯体感觉皮层的D3胡须代表区被注射生物素化葡聚糖胺（biotinylated dextran amine）以顺行标记轴突，图像中可见该顺行标记的轴突。标记物通过组织学方法进行可视化，切片经复染色以显示细胞构筑。在部分穿过感觉运动皮层的脑切片中，已实现细胞色素氧化酶阳性桶状结构的可视化。
