方法材料。刺猬（Erinaceus europaeus）的大脑示意图见图1。Retzius [1897]描述了嗅觉区域，Gray [1924]在一篇关于负鼠（Didelphys virginiana）的论文中详细描述了一种密切相关的大脑的解剖和细胞结构。我们可以看到，刺猬的新皮层并不像大多数哺乳动物那样与大脑的嗅觉部分重叠，而是形成一个不完整的帽，帽下的梨状叶向侧面凸出。在从上方打开颅骨后，电极可以很容易地到达脑叶的这一部分，嗅球也很容易接近。
METHOD Material. Diagrams of the brain of the hedgehog (Erinaceus europaeus) are given in Fig. 1. There isa description of the olfactory regions by Retzius [1897] and a full account of the anatomy and cell structure of a closely related brain ina paper by Gray [1924] on the opossum (Didelphys virginiana). It will be seen that in the hedgehog the neo-cortex does not overlap the olfactory part of the cerebrum as in most mammals, but forms an incomplete cap below which the pyriform lobe bulges laterally. This part of the lobe can easily be reached by an electrode after the skull has been opened from above and the olfactory bulb is also very easily accessible.
