cortical mantle thickness

Impulsive personality traits are often predictive of risky behavior, but not much is known about the neurobiological basis of this relationship. The high-inflammation group had significantly greater cortical thinning than the low-inflammation group in four Global thinning was apparent by middle age. Main Outcome Measures Cortical thickness and change in cortical thickness on a vertex-by-vertex basis across the cortical mantle, measures of functional and symptomatic outcome, and cumulative intake of antipsychotics during the scan interval. adrenal cortex (cortex of adrenal gland) the outer, firm layer comprising the larger part of the adrenal gland; it secretes mineralocorticoids, androgens, and glucocorticoids. cortex [kor´teks] (pl. The individual thickness estimates from the results of this analysis then were combined across the 30 subjects by using a high-resolution, surface-based averaging technique that aligns cortical folding patterns ().The results of this procedure, shown in Fig. Mean cortical thickness did not differ between the groups. Over time, excessive cortical thinning was found in widespread areas on the cortical mantle, most pronounced bilaterally in the temporal cortex and in the left frontal area. Estimates of cortical thickness at 81,924 vertices covering the entire cortical mantle were regressed on attentional absorption scores across the whole sample. The cortex is the thin, outermost layer of nerve cell tissue of the brain, typically measuring a few millimeters in thickness. Cortical thickness was estimated as the distance between the gray/white boundary and the outer cortical surface, resulting in a continuous estimate across the cortical mantle. cortical thickness at every voxel of each hemisphere with a conservative threshold of Po.01.2 Regional clusters in which cortical thickness differed according to level of in-flammation were identified and examined independently. Regardless of the algorithms used to detect the surfaces and calculate thickness, it is necessary to segment the 3). Poor outcome in patients was associated with more pronounced cortical thinning. We investigated whether thickness of the cortical mantle varied as a function of impulsive traits and whether such variation also explained recent risky behavior. Cortical thickness reduction was observed in the left pars triangularis and right pars opercularis (Table 2, Fig. cor´tices) (L.) the outer layer of an organ or other structure, as distinguished from its inner substance or medulla. Men and women showed a similar degree of global thinning, and did not differ in mean thickness in the younger or older groups. adj., adj cor´tical. The topology of the cerebral cortex has been proposed to provide an important source of constraint for the organization of cognition. Further, despite the fact that cortical volume is a product of cortical thickness and surface area, there has been little attempt to integrate findings across these different measures of gray matter structure. In a sample of twins ( n = 1113), we determined structural covariance of thickness to be organized along both a posterior-to-anterior and an inferior-to-superior axis.
