Modification of chemical and magnetic extraction techniques has yielded biogenic magnetite/maghemite from human hippocampal tissue. Particles were identified using high resolution transmission electron microscopy, electron diffraction and elemental analysis. Though its presence has been inferred from magnetic analyses, this is the first direct observation of magnetic biominerals from the hippocampus.
化学和磁性提取技术的改进已从人类海马组织中获得了生物源磁铁矿/磁赤铁矿。使用高分辨率透射电子显微镜、电子衍射和元素分析对颗粒进行了鉴定。尽管通过磁性分析已推断出其存在，但这是首次对海马体中的磁性生物矿物进行直接观察。
