It seems strange that SWEDENBORG did not here supply an account of these interesting and convincing cases, which he nevertheless, as we have seen, was well acquainted with. For his habit is to furnish the chapters of his works with an introduction in which he reports, often in very detailed form, the statements of the authors upon which he bases his conclusions. Since in the present case such an account is lacking, this may depend: either upon the fact that this last anatomical work of SWEDENBORG, ›De Cerebro›, was not quite completed and finally edited for the press, or thereon that Dr. RUDOLF TAFEL, who edited the translation which is now accessible in print, excluded it. For Dr. TAFEL says in a note that the introduction to the chapter in question would be introduced into Part II., chapters 1 and 2, but—Part II. was never printed! Since, however, the Royal Swedish Academy of Sciences will publish ›De Cerebro› in its edition of SWEDENBORG’s Scientific works, this question will no doubt be cleared up. But this much is quite clear from what has already been adduced, that the cases of paralysis which SWEDENBORG previously quoted in a brief form are in the original descriptions reported so completely and in such detail that one can without the least doubt localize the cortical lesions reported in those cases in the anterior (superior) region of the cerebrum. We now pass to an examination of the _anatomical_ literature to which SWEDENBORG had access. And, as we shall find, we can here see whence SWEDENBORG derived _material for his detailed doctrine_ concerning the function of the brain’s anterior region. This becomes evident on comparing SWEDENBORG’s mode of thinking of the brain’s psychical activity with the descriptions of preceding authors in anatomy. The group of nuclei, ›_corpus striatum_›, in the cerebrum had been an object of special interest for preceding authors. The Englishman, THOMAS WILLIS, had for example in his ›Cerebri anatome› (published in 1667) portrayed them as a kind of junction, ›internodes›, by which the cerebrum coheres with the medulla oblongata; and he pays special attention to it on account of its peculiar structure (›The Brain›, No. 476); and he is said even to have attributed to them the ›Sens commun›.[76] And the professor in Montpellier, RAIMOND VIEUSSENS, had given in his ›Neurographia universalis› (published in 1685) a very exact description of the ›corpus striatum›, (not only of its ›superior nuclei›: ›Corp. striat. sup. ant.› = Nucleus caudatus and ›Corp. striat. sup. post.› = ›Thalamus opticus›, but also of its lower lateral nucleus = ›Nucleus lentiformis›) as also of the mighty medullary tract of nerve fibres, i. e., ›capsula interna›, which passes through the same, and which on the one hand is distributed to the brain, especially to its anterior (superior) region, and on the other hand by means of the nerves radiates into the various parts of the body.
