Abstract
The superior longitudinal fasciculus (SLF) I is known to be involved in regulation of higher aspects of motor function. Using diffusion tensor imaging (DTI), we attempted to identify the SLF I and to investigate the anatomical characteristics of the SLF I in the human brain. We recruited 30 healthy subjects for this study. The SLF I was obtained using the FMRIB Software Library. The seed region of interest (ROI) was given at the superior parietal lobule (SPL) and the target ROI was the supplementary motor area (SMA) along with the dorsal part of the premotor area (PMA). Values of fractional anisotropy (FA), mean diffusivity (MD), and tract volume were measured. The SLF I originated from the SPL and medial parietal cortex, passed through the white matter of the SPL and superior frontal gyrus, and then terminated in the SMA and dorsal PMA. There were no significant differences between hemispheres in terms of the FA, MD, and tract volume. We present with the anatomical characteristics of the SLF I in the human brain using DTI. We think that the methodology and results of this study would be helpful to researchers in this field. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
