A Connectomic Atlas of the Human Cerebrum-Chapter 14: Tractographic Description of the Frontal Aslant Tract

Robert G Briggs et al. Oper Neurosurg. .

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 frontal aslant tract.

FIGURE 1.
Simplified tract map showing the structural connections that integrate within the FAT. Connections between cortical areas are color-coded based on the parcellation of origin (eg, blue arrows indicate structural connections from origin 8BL to areas 44 and MI). Note that arrows are not meant to imply the direction of information transmit.

Structural connections from cortical regions integrating within the FAT. A, Connections from area 8BL to regions 44 and MI of the IFG and anterior insula, respectively. B and C, Connections from SFL to areas FOP1, FOP3, FOP4, and MI of the insular-opercular cortex. C is an oblique view of SFL connections to better identify region FOP3 which lies behind areas MI and FOP4. All tractography images are shown on T1-weighted magnetic resonance (MR) images in the coronal plan.

Structural connections from cortical regions integrating within the FAT. A, Connections from area S6-8 to regions 44, 6r, and FOP4 of the IFG and frontal operculum. B and C, Connections from 6ma to areas 44, FOP3, FOP4, and MI of the IFG, frontal operculum and anterior insula. C is an oblique view of 6ma connections to better identify region FOP3 which lies behind areas MI and FOP4. All tractography images are shown on T1-weighted MR images in the coronal plan.
