Cortical intensity profiles sampled across BigBrain isocortex (v1.0)

BigBrain is a publicly available 3D model of the human brain at 20 micron isotropic resolution, reconstructed from 7404 histological tissue sections that have been stained for cell bodies. This dataset contains profiles of the staining intensities, sampled at surface positions across the complete isocortex, ranging from the pial surface to the gray/white matter boundary. Since BigBrain's staining is sensitive to cell bodies, profiles are an approximate local measure of cortical cell density.

BigBrain是一款公开可用的人类大脑三维模型，其分辨率为20微米各向同性分辨率（isotropic resolution），由7404张经过胞体染色的组织学切片（histological tissue sections）重建得到。该数据集包含染色强度剖面，在覆盖整个新皮层（isocortex）的表面位点进行采样，采样范围从软脑膜表面（pial surface）延伸至灰白质边界（gray/white matter boundary）。由于BigBrain的染色对胞体具有敏感性，上述剖面可作为皮层细胞密度的近似局部度量指标。
