Abstract

In this supplement, we show a comprehensive anatomic atlas of the human cerebrum demonstrating all 180 distinct regions comprising the cerebral cortex. The location, functional connectivity, and structural connectivity of these regions are outlined, and where possible a discussion is included of the functional significance of these areas. In this chapter, we specifically address the regions integrating to form the uncinate fasciculus.

FIGURE 1.
Simplified tract map showing the structural connections that integrate within the UF. Connections between cortical areas are color-coded based on the parcellation of origin (eg, red arrows indicate structural connections from origin TGd to areas 44, FOP4, 45, FOP5, OFC, pOFC, 47L, and 47S). Note that arrows are not meant to imply the direction of information transmit.

FIGURE 2.
Uncinate connections from temporal polar region STGa. Area STGa only has 1 structural connection integrated within the uncinate to area 47L. This connection is shown in the left cerebral hemisphere on T1-weighted MR images in the A, sagittal and B, axial planes. All parcellations are identified with white arrows and corresponding labels.
FIGURE 3.
FIGURE 3.
Uncinate connections from temporal polar region TGd. Area TGd has multiple structural connections integrated within the uncinate to areas 44, FOP4, 45, FOP5, OFC, pOFC, 47L, and 47S. A subset of these connections to regions OFC and pOFC are shown in the left cerebral hemisphere on T1-weighted MR images in the A, sagittal and B, axial planes. All parcellations are identified with white arrows and corresponding labels.
