This paper describes the treatment and results of the fixation procedure, extraction, dissection, and data collection of the preserved Late Pleistocene brain of the mummified specimen from permafrost. The partial carcass of the Woolly mammoth (Mammuthus primigenius (Blumenbach 1799)) nicknamed “Yuka” was found in 2010 on the Dmitrii Laptev Sea coast (Northern Yakutia, Russia). It dates to 39,440–38,850 cal. BP. This fossil presents the unique opportunity to study the preserved brain from permafrost, with well-defined major gross anatomy features of the cerebrum and cerebellum and internal structures revealed by Computed tomography (CT) and Magnetic resonance imaging (MRI). Anatomical description, CT data including volumetry, and results of the histological and electron microscopy study of the specimen are provided.
