A three-dimensional thalamocortical dataset for characterizing brain heterogeneity: Microstructure Annotations (NumPy)

In this dataset, we provide a collection of images acquired from multiple brain regions that span an intact thalamocortical pathway (Agmon & Connors, 1991). Along with these images, we provide: (1) annotations of microstructures in the images that classify each pixel in the as either a: cell, myelinated axon, blood vessel, or background. All of these image volumes and annotations are stored as NumPy arrays. Pixels are labeled as follows: 0-> no label (background); 1-> vasculature; 2-> cell body; 3-> myelinated axon. Annotated images are provided for four regions of interest: Cortex, Striatum, TRN in thalamus, and the Zona Incerta (ZI).

本数据集收录了源自多个脑区的图像集合，这些图像覆盖完整的丘脑皮层通路（Agmon & Connors, 1991）。随上述图像一同提供的还有：(1) 图像微结构标注，该标注将每张图像中的每个像素划分为四类：细胞、有髓轴突、血管或背景。所有图像体数据与标注均以NumPy数组格式存储。像素标签规则如下：0代表无标注（背景）；1代表脉管系统；2代表细胞体；3代表有髓轴突。我们为四个感兴趣脑区提供了带标注的图像：大脑皮层、纹状体、丘脑内的丘脑网状核（TRN）以及未定带（Zona Incerta, ZI）。
