Cortical atlases provide consistent divisions of the human cortex into areas that have common structural as well as meaningful and distinctive functional characteristics. They constitute a fundamental tool to study and quantify changes in healthy and pathological states. Historically, the most widely used atlases follow the cytoarchitecture described by Brodmann and/or the myeloarchitectonic characteristics described by Vogt-Vogt. These histological approaches have since been combined to the standard anatomical nomenclature of gyri and sulci, referring to the corresponding cytoarchitectonic area(s) present in a gyrus, when applicable or necessary (e.g. area 4 of Brodmann in the pre-central gyrus). More recently, common functional features depicted by resting state functional MRI have guided the division of the cortex into functional regions of interest. However, to date, there are no human MRI atlases that divide the cortex considering the common evolutionary changes experienced by the mammalian cortex. Hence, the present dataset describes the PaleoArchiNeo (PAN) Human Brain, a voxel-based atlas that divides the human cortex into five regions of interest (ROIs) following a phylogenetic approach: 1- archicortex, 2- paleocortex, 3- peri-archicortex, 4- proisocortex, 5- neocortex, and thirty neocortical sub-ROIs that follow the gyral .The masks of the ROIs and sub-ROIs were segmented on the T1-weighted MNI ICBM 152 2009c symmetric average brain MRI model, the latest version of the most widely used standard brain template. The segmentations have been performed manually by anatomist experts, following the MRI anatomical landmarks that have been previously described, correlated, and validated with histology by other groups.
皮质图谱将人类皮质一致划分为具有共同结构以及有意义且独特功能特征的区域。它们是研究和量化健康及病理状态变化的基本工具。从历史上看，使用最广泛的图谱遵循布罗德曼描述的细胞构筑以及沃格特 - 沃格特描述的髓鞘构筑特征。此后，这些组织学方法已与脑回和脑沟的标准解剖命名法相结合，在适用或必要时，指的是脑回中存在的相应细胞构筑区域（例如中央前回中的布罗德曼第4区）。最近，静息态功能磁共振成像所描绘的共同功能特征指导了将皮质划分为感兴趣的功能区域。然而，迄今为止，尚无考虑哺乳动物皮质共同进化变化来划分皮质的人类磁共振成像图谱。因此，本数据集描述了古 - 原 - 新（PAN）人类大脑，这是一个基于体素的图谱，它按照系统发育方法将人类皮质划分为五个感兴趣区域（ROI）：1 - 原皮质，2 - 古皮质，3 - 周原皮质，4 - 前异皮质，5 - 新皮质，以及三十个遵循脑回的新皮质子ROI。ROI和子ROI的掩码是在T1加权的MNI ICBM 152 2009c对称平均脑磁共振成像模型上分割的，这是最广泛使用的标准脑模板的最新版本。分割是由解剖学家专家手动进行的，遵循先前描述的磁共振成像解剖标志，这些标志已由其他团队与组织学进行了关联和验证。
