在20世纪90年代的4月和5月，当我还是一名在哈佛医学院攻读德怀特教授高级解剖学选修课的本科生时，我不断地惊喜地发现，大脑的许多纤维束、细胞核和一些神经的深层起源可以用研究身体其他部位的方法进行简单而准确的解剖，这种方法比研究身体其他部位的方法稍作修改。由于德怀特教授和沃伦博士的好意，我被允许使用大量的大脑进行解剖，在此过程中，新的和令人印象深刻的著名结构的图片不断出现。它们是如此新颖和独特，以至于一个不熟悉早期解剖学家原作的人几乎会相信，一种解决大脑解剖学难题的新方法已经被发现了。试图通过解剖来追踪纤维束似乎是研究大脑中较大结构的最自然的方法，也是最先想到的方法。因此，在显微镜出现之前，在前人尝试的各种大脑研究方法中，纤维束解剖占有一席之地，许多较大的结构被相当熟练地展示出来，这并不奇怪。然而，随着显微镜的出现，这种方法就被忽视了。在今天的教科书中，一个也找不到
In April and May, 190s) while as an undergraduate pursuing the elective course in advanced anatomy in the Harvard Medical School under Professor Dwight, I was repeatedly and agreeably surprised with the ease and accuracy with which many of the fiber tracts of the brain, the nuclei, and the deep origins of some of the nerves could be dissected by methods slightiy modified from those employed in studying other parts of the body. Through the kindness of Professor Dwight and Dr. Warren, I was allowed to use a large number of brains for dissection, in the course of which new and impressive pictures of well-known structures were continually occurring. With such novelty and distinctness did these stand out that one not familiar with the original works of the early anatomists would almost be convinced that a new method of attacking the difficult problems of brain anatomy had been discovered. The attempt to follow fiber tracts by dissection seems to be the most natural method for investigation of the larger structures in the brain, and one that would be first thought of. So it is not surprising to learn that before the advent of the microscope, among the different methods of brain study attempted by our predecessors, fiber-tract dissection had a place, and many of the larger structures were displayed with considerable skill. With the introduction of the microscope, however, this method became neglected. and one cannot see in the text-books of to-day a single
