发展研究以及儿科临床活动至关重要地依赖于非侵入性和无痛的脑记录技术，如脑电图（EEG）和近红外光谱（NIRS）。然而，这两种技术都是从头皮上测量皮层活动，而没有对记录的大脑结构有精确的了解。因此，在外部解剖标志和大脑内部结构之间进行准确可靠的映射是以非侵入性方式定位大脑来源的基础。在这里，我们使用MRI检查了16名婴儿（产后3-17周）的10-20传感器放置系统与大脑结构之间的关系。我们提供了一个包裹在94个区域的婴儿模板，我们报告了传感器位置的可变性，同时报告了六个主要皮层沟（额上和额下沟，中央沟，外侧裂缝，颞上沟和顶内沟）的解剖可变性，以及这些婴儿中传感器与重要皮层标志之间的距离。婴儿和成人的主要区别在于O1-O2， T5-T6通道，它们比成人的低结构。我们没有发现头皮和脑包膜之间的距离有任何不对称。然而，由于雅可夫力的作用，P3-P4与右侧侧裂的背侧和正面距离不相同。本研究通过提供标准化通道相对于婴儿大脑结构定位的准确描述，有助于完善功能性认知发展的假设。模板和地图集可在我们的网站（http://www.unicog.org/pm/pmwiki.php/Site/InfantTemplate）上公开获取。(C) 2014 Elsevier Inc .版权所有
Developmental research, as well as paediatric clinical activity crucially depends on non-invasive and painless brain recording techniques, such as electroencephalography (EEG), and near infrared spectroscopy (NIRS). However, both of these techniques measure cortical activity from the scalp without precise knowledge of the recorded cerebral structures. An accurate and reliable mapping between external anatomical landmarks and internal cerebral structures is therefore fundamental to localise brain sources in a non-invasive way. Here, using MRI, we examined the relations between the 10-20 sensor placement system and cerebral structures in 16 infants (3-17 weeks post-term). We provided an infant template parcelled in 94 regions on which we reported the variability of sensors locations, concurrently with the anatomical variability of six main cortical sulci (superior and inferior frontal sulcus, central sulcus, sylvian fissure, superior temporal sulcus, and intraparietal sulcus) and of the distances between the sensors and important cortical landmarks across these infants. The main difference between infants and adults was observed for the channels O1-O2, T5-T6, which projected over lower structures than in adults. We did not find any asymmetry in the distances between the scalp and the brain envelope. However, because of the Yakovlean torque pushing dorsally and frontally the right sylvian fissure, P3-P4 were not at the same distance from the posterior end of this structure. This study should help to refine hypotheses on functional cognitive development by providing an accurate description of the localization of standardised channels relative to infants' brain structures.
