“…Second, the maps can be used as templates for the parcellation of the white matter and tract-specific monitoring of MR parameters. In the past, tractography results have been used as ROI to perform tract-specific quantification of MR parameters (Virta et al, 1999;Xue et al, 1999;Stieltjes et al, 2001;Glenn et al, 2003;Wilson et al, 2003;Partridge et al, 2004;Berman et al, 2005;Pagani et al, 2005;Jones et al, 2006;Kanaan et al, 2006). The probabilistic approach described in this paper can be considered as an extension of this idea.…”

“…We can extend this approach in a more systematic way by identifying the 3D trajectories of individual white matter tracts using 3D tract reconstruction, or tractography (Conturo et al, 1999;Mori et al, 1999;Basser et al, 2000;Poupon et al, 2000;Parker et al, 2002). Once a tract of interest is defined in three dimensions, we can superimpose its coordinates on MR parameter maps to perform quantitative tract-specific monitoring of pathological conditions (Virta et al, 1999;Xue et al, 1999;Stieltjes et al, 2001;Glenn et al, 2003;Wilson et al, 2003;Partridge et al, 2004;Pagani et al, 2005).…”

Tract probability maps in stereotaxic spaces: Analyses of white matter anatomy and tract-specific quantification

et al. 2008

Diffusion tensor imaging (DTI) is an exciting new MRI modality that can reveal detailed anatomy of the white matter. DTI also allows us to approximate the 3D trajectories of major white matter bundles. By combining the identified tract coordinates with various types of MR parameter maps, such as T 2 and diffusion properties, we can perform tract-specific analysis of these parameters. Unfortunately, 3D tract reconstruction is marred by noise, partial volume effects, and complicated axonal structures. Furthermore, changes in diffusion anisotropy under pathological conditions could alter the results of 3D tract reconstruction. In this study, we created a white matter parcellation atlas based on probabilistic maps of 11 major white matter tracts derived from the DTI data from 28 normal subjects. Using these probabilistic maps, automated tract-specific quantification of fractional anisotropy and mean diffusivity were performed. Excellent correlation was found between the automated and the individual tractography-based results. This tool allows efficient initial screening of the status of multiple white matter tracts.

“…Historically, much of what we know about the intricate processes of early brain development came from post mortem studies in human fetuses, neonates, and non-human primates (Flechsig, 1920;Goldman-Rakic, 1987;Innocenti and Price, 2005;Kostovic, 2002;LaMantia and Rakic, 1990). With the increasing availability of high-quality neuroimaging techniques, including anatomical sequences customized to the developing neonatal and fetal brain, diffusion weighted imaging (DWI) and functional MRI, as well as electrophysiology recordings including electroencephalography (EEG), it has now become feasible to study early human brain development in unprecedented detail in vivo Counsell et al, 2007;Fransson et al, 2007;Huppi et al, 1998;Maas et al, 2004;Omidvarnia et al, 2014;Partridge et al, 2004;Smyser et al, 2001; Thomason et al, 2013;Toulmin et al, 2015;van den Heuvel et al, 2014). These advances have led to exciting new insights into both healthy and atypical macroscale brain network development and have paved the way to bridge the gap between the brain's neurobiological architecture and its behavioral repertoire.…”

The emergence of functional architecture during early brain development

Early human brain development constitutes a sequence of intricate processes resulting in the ontogeny of functionally operative neural circuits. Developmental trajectories of early brain network formation are genetically programmed and can be modified by epigenetic and environmental influences. Such alterations may exert profound effects on neurodevelopment, potentially persisting throughout the lifespan. This review focuses on the critical period of fetal and early postnatal brain development. Here we collate findings from neuroimaging studies, with a particular focus on functional MRI research that interrogated early brain network development in both health and high-risk or disease states. First, we will provide an overview of the developmental processes that take place from the embryonic period through early infancy in order to contextualize brain network formation. Second, functional brain network development in the typically developing brain will be discussed. Third, we will touch on prenatal and perinatal risk factors that may interfere with the trajectories of functional brain wiring, including prenatal substance exposure, maternal mental illness and preterm

“…In healthy preterm infants, FA increase is observed in motor and sensory tracts with increasing postnatal age (PNA, i.e., age in weeks since birth). Commissural tracts and deep projections seem to mature earlier than subcortical and associative pathways (Partridge et al, 2004). Comparison of FA values is therefore useful in demonstrating differences in brain structural development between groups.…”

Accelerated cerebral white matter development in preterm infants: A voxel-based morphometry study with diffusion tensor MR imaging

et al. 2008

Twenty-seven preterm infants were compared to 10 full-term infants at term equivalent age using a voxel-based analysis of diffusion tensor imaging of the brain. Preterm infants exhibited higher fractional anisotropy values, which may suggest accelerated maturation, in the location of the sagittal stratum. While some earlier findings in preterm infants have suggested developmental delays, the results of this study are more consistent with accelerated white matter development, possibly as a result of increased sensorimotor stimulation in the extrauterine environment. These results are the first to suggest that the increased intensity of stimulation associated with preterm birth may advance the process of white matter maturation in the human brain. Questions remain about whether these findings reflect acceleration of the process of white matter maturation generally, or localized alterations induced specifically by activity in affected pathways.
