MRI of normal brain maturation.
The unprecedented gray/white differentiation obtained with magnetic resonance imaging (MRI) has created a unique opportunity to trace the normal process of myelination. Fifty-nine children referred for evaluation of a nonneurologic problem or a nonspecific neurologic complaint were studied with MRI using spin-echo technique. Children ranged in age from term (40 weeks intrauterine) to 16 years. ...
متن کاملTrajectories of cortical surface area and cortical volume maturation in normal brain development
This is a report of developmental trajectories of cortical surface area and cortical volume in the NIH MRI Study of Normal Brain Development. The quality-controlled sample included 384 individual typically-developing subjects with repeated scanning (1-3 per subject, total scans n=753) from 4.9 to 22.3 years of age. The best-fit model (cubic, quadratic, or first-order linear) was identified at e...
متن کاملBrain maturation of the adolescent rat cortex and striatum: Changes in volume and myelination
Longitudinal studies on brain pathology and assessment of therapeutic strategies rely on a fully mature adult brain to exclude confounds of cerebral developmental changes. Thus, knowledge about onset of adulthood is indispensable for discrimination of developmental phase and adulthood. We have performed a high-resolution longitudinal MRI study at 11.7T of male Wistar rats between 21days and six...
متن کاملP81: Psychosocial Stress of Maternal Deprivation Enhanced Volume of Lateral Ventricle in Rat Brain
Brain areas implicated in the stress response include the amygdala, hippocampus and prefrontal cortex. Neonatal stimulation of an animal by handling or by enhanced maternal care induces at adult age a decrease of the hypothalamo-pituitary adrenal (HPA) response to stressors, a decrease of anxiety in a novel environment, and neuroanatomical changes. In this present study we demonstrated that mat...
متن کاملMaturation of sperm volume regulation in the rat epididymis.
Sperm maturation in the epididymis may involve differences between mature and immature spermatozoa in their volume regulatory osmolyte response. Spermatozoa obtained from the rat caput and cauda epididymidis were examined for their ability to regulate volume after transfer from in situ epididymal osmolality (measured to be 343 +/- 13 and 365 +/- 19 mmol kg(-1), respectively) to that of the fema...
