[Context Link] COMMENTS This article illustrates an anatomic detail of the organization of the hemispheres and is an interesting addition to the usual neurosurgical literature. It is an example of one of the strengths of Neurosurgery—enlarging the scope of noteworthy facts with which a neurosurgeon should be familiar. In this article and previous articles describing the same technique (1, 2), I found surgery of the temporal lobe to treat epilepsy interesting. The three-dimensional information available from these specimens is extremely useful compared with the studies of these fiber bundles in the atlas and textbooks. Johannes Schramm Bonn, Germany 1.

Acta Neurochir (Wien) 92:29–36, 1988. Bibliographic Links Document Delivery Library Holdings [Context Link] One of the hidden strengths of this important anatomic contribution lies in its ability to further define pathways of glioma dissemination so commonly seen throughout the white matter tracts. The myelinated fascicles or fiber tracts serve as a substrate for neoplastic cells to invade
adjacent territories. This occurs via association, commissural, and projection pathways and helps to explain the increasing phenomena of gliomatosis cerebri and mutlicentricity. For example, most insular-based gliomas have components in the temporal and frontal lobes. The detailed demonstration of the uncinate fasciculus clearly documents how this takes place. This fasciculus must be identified and entered, underlying the middle cerebral artery bifurcation, during removal of insular gliomas. Our knowledge of subcortical functional pathways continues to be deficient, and, unfortunately, an anatomic study such as this cannot provide the missing pieces to the puzzle. Notwithstanding, this is a valuable anatomic study using the fiber dissection technique, which will serve as an excellent substrate to aid in our understanding of these critical pathways during surgery and to explain the pathophysiology of certain disease states that we encounter on a daily basis. Mitchel S. Berger San Francisco, California This is an unusual and interesting article, describing an older anatomic technique that is perhaps underappreciated today. Türe et al. present a description of the fiber dissection technique, a “tour" of hemispheric fiber tract anatomy using the technique, and a fascinating historical account. This is not a quantitative description of fiber tracts based on their investigation; however, it does provide a better appreciation for the three-dimensional, nonlinear organization of the brain and its importance to neurosurgery. This is sufficient reward for the reader; however, if one also is left with the temptation to visit the anatomy or pathology department and try the technique, à la Willis, Bell, Reil, Gall, Rolando, and Meynert, that is icing on the cake.
