The Heschl Gyrus (HG), which includes the Primary Auditory Cortex (PAC), lies on the upper surface of the superior temporal gyrus (T1). It has been the subject of growing interest in the fields of neuroscience over the past decade. Given the considerable interhemispheric and interindividual variability of its morphology, manual labelling remains the gold standard for its radio-anatomical study. The aim of this study was to revisit the original work of Richard L. Heschl, to provide a broad overview of the available anatomical knowledge and to propose a manually labelled 3D digital model.
We reviewed existing works on the HG, from Heschl's original publication of 1878, Dejerine neuroanatomical atlas of 1895 to the most recent digital atlases (Julich-Brain Cytoarchitectonic Atlas, the Human Connectome Project). Our segmentation work was based on data from the BigBrain Project and used the MRIcron 2019 software.
The original publication by Heschl has been translated into French and English. We propose a correspondence of previous nomenclatures with the most recent ones, including the Terminologia Neuroanatomica. Finally, despite the notable anatomical variability of the HG, clear and coherent segmentation criteria allowed us to generate a 3D digital model of the HG.
Heschl's work is still relevant and could impulse further anatomical and functional studies. The segmentation criteria could serve as a reference for manual labelling of the HG. Furthermore, a thorough, and historically based understanding of the morphological, microstructural and functional characteristics of the HG could be useful for manual segmentation.
颞横回（HG）包含初级听觉皮层（PAC），位于颞上回（T1）的上表面。在过去十年中，它一直是神经科学领域日益关注的对象。鉴于其形态在半球间和个体间存在相当大的变异性，手动标注仍是其放射解剖学研究的金标准。本研究的目的是重新审视理查德·L·赫施尔的原始著作，提供现有解剖学知识的全面概述，并提出一个手动标注的三维数字模型。
我们回顾了关于颞横回的现有著作，从赫施尔1878年的原始出版物、1895年的德热里纳神经解剖图谱到最新的数字图谱（朱利希脑细胞构筑图谱、人类连接体计划）。我们的分割工作基于大大脑计划的数据，并使用了MRIcron 2019软件。
赫施尔的原始出版物已被翻译成法语和英语。我们提出了先前命名法与最新命名法的对应关系，包括《神经解剖学命名法》。最后，尽管颞横回存在显著的解剖变异性，但清晰连贯的分割标准使我们能够生成颞横回的三维数字模型。
赫施尔的工作仍然具有相关性，并可能推动进一步的解剖学和功能研究。分割标准可作为颞横回手动标注的参考。此外，对颞横回的形态、微观结构和功能特征进行全面的、基于历史的理解，可能有助于手动分割。
