“…In Figure 5, diffusivity, radial ( 1 ) and tangential [( 2 ϩ 3 )/2] to the pial surface at two representative locations (prelimbic and somatosensory), is shown. In both cortices, the tangential diffusivity remains stable throughout postnatal development, whereas the radial diffusivity of the somatosensory cortex decreases rapidly in the first 2 weeks, in agreement with previous reports of human neonatal studies (Deipolyi et al, 2005).…”

“…Human studies revealed similar results. Deipolyi et al (2005) also found evidence of regional heterogeneity in human cortical development from the FA measurement of the superior frontal, superior occipital, precentral, and postcentral gyri.…”

“…Similarly, a study of glucosemetabolism using PET scans in children showed that local cerebral metabolic rates for glucose were equally high in the pre-and postcentral gyri in infants less than 5 weeks old and that glucose metabolism gradually increased in the other neocortical regions (Chugani et al, 1987). A study of diffusion tensor imaging (DTI) in premature newborns showed that fractional anisotropy levels, measurements of the directional diffusivity of water, were quite similar between the precentral and postcentral gyri and that fractional anisotropy levels in the pre and postcentral gyri were lower than those in the superior frontal or superior occipital gyri (Deipolyi et al, 2005). A study using a quantitative DTI fiber tracking technique in premature newborns failed to indicate a difference in the amount of subcortical fibers reaching the posterior limb of the internal capsule between the precentral and postcentral gyri (Berman et al, 2005).…”

“…Regional differences in cortical diffusion anisotropy have been reported in prematurely born human infants (Deipolyi et al, 2005) and in developing baboon brain analyzed postmortem (Kroenke et al, 2005), but the underlying biological source of this variation has not been described. These previous studies analyzed variation between limited regions of interest or within individual MRI slices.…”

“…The physical relationship between diffusion MRI measurements and cellular scale cortical microarchitecture is under active investigation (Kroenke et al, 2004;Jespersen et al, 2007). Empirically, radial diffusion anisotropy progressively declines throughout cortical maturation (McKinstry et al, 2002;Deipolyi et al, 2005) in parallel with elaboration of dendritic and axonal arbors throughout the cortical sheet. In contrast to the pattern in cerebral cortex, diffusion anisotropy increases with maturation in white matter (Huppi et al, 1998;Neil et al, 1998).…”
