The convolutions of the insula, the Sylvian opercula and the deep face of the first temporal convolution, have been removed to show the fibers of the external capsule, the uncinate fascicle and the arcuate fascicle or superior longitudinal fascicle. Arc, arcuate fascicle or superior longitudinal fascicle. - Ce, external capsule. - F2, second frontal convolution. - f2, second frontal sulcus. - F3(C), Cape of the third frontal convolution. - f4, olfactory sulcus. - Fa, ascending frontal convolution. - fa(pri), U-shaped fibers of the inferior pre-Rolandic sulcus. - Fu, uncinate fascicle. - io, intra- occipital sulcus. - ip, intra-parietal sulcus. - O1, O2, O3, first, second and third occipital convolutions. - oF1, oF2, oF3, orbitary part of thefirst, second, and third frontal convolutions. - oF1(Gr), rectus gyrus. - P1, P2, first and second parietal convolutions. - Pa, ascending parietal convolution. - Pc, pli courbe. - po, occipito-parietal fissure. - por, post-Rolandic sulcus. - prs, superior pre-Rolandic sulcus. - R, Rolando fissure. - T1, T2, first and second temporal convolutions. - t1, parallel or first temporal sulcus. - t'1, vertical branches of the parallel sulcus. - t2, second temporal sulcus. - VS, Valley of Sylvius.

The edges of the Sylvian fissure have been outspreaded to show the insula and the retro-insular region. The uncinate fascicle, the arcuate fascicle or superior longitudinal fascicle and the vertical occipital fascicle are shown in transparency. Arc, arcuate fascicle or superior longitudinal fascicle. - F2, F3, second and third frontal convolutions. - f2, second frontal sulcus. - f3, third frontal sulcus or H sulcus.

C. Legend of Curran EJ (1909) Fig. 1. This is a photograph from a dissection made to show the general course of the fasciculus occipito-frontalis inferior from the lateral aspect of the brain. F.o.f.i.1, F.o.f.i.2, F.o.f.i.3, F.o.f.i.4, fasciculus occipito-frontalis inferior; F. unc., fasciculus uncinatus; F. Rol., fissure of Rolando; Ext. c., external capsule, with window cut in it to show Nuc. lent., nucleus lentiformis and arteries to same; F. arc2, fasciculus arcuatus (horitontal part); F. arc.1 ant. br., anterior bundles from descending branch of fasc. arc.; F. arc.3 post. br. and F. arc.4 post. br., posterior descending branch of fasc. arc.; Fibers from c.c., fibers from corpus callosum chiefly, but some arcuate fibers with them. The white substance of superior temporal lobe in the upper portion consists of fibers from the fasciculus arcuatus, internal capsule, external capsule, and corpus callosum. Fibers from tap., fibers from the tapetum perforating the corona rad. and the F.o.f.i. to proceed to the end of the temp. lobe. F. tras. o., a posterior part of the fasc. transversus occipitalis. In this dissection most of this bundle is removed showing a large window through which the F.o.f.i. can be seen. At the anterior of this window a small part of the fasc. trans. occ. still remains.

D. Legend of Curran EJ (1909) Fig. 2. This is a photograph of a dissection from the lateral aspect, made to show the anatomical relationship of the fasciculus occipito-frontalis inferior to adjacent anatomical structures. Occ. lobe, occipital lobe; F.o.f.i.1, F.o.f.i.2, F.o.f.i.3, F.o.f.i.4, fasciculus occipito-frontalis inferior; F. trans. o., a large bundle of fibers, the posterior part of which belongs to the vertical transverse occipital fasciculus and the anterior part belongs to the fasc. arcuatus plus a considerable quantity from the corpus callosum; F. o. t., fasciculus occ.- temporalis sweeping back from the white substance of the sup. temp. convolution; Ext. c., external capsule; Nuc. lent., nucleus lentiformis showing through a window in external capsule; P. of opt. thal., pulvinar of opt. thalamus, also showing under and in front of it are the geniculate bodies and the crus; Cna (t.pt.), the broken edge of the temporal part of the corona radiata lying on the descending fibers of the tapetum, stria semi-circularis and the tail of the caudate nucleus which latter does not show well in this picture; F. a. t., fasc. amygdalo-temporalis; F. unc., fasc. uncinatus.
