Morphometric analysis was performed on three-dimensional MRI scans of 10 male and 10 female young adults with four principal objectives: (1) to characterize in vivo volumes of whole brain and substructures, (2) to explore volumetric symmetry in bilateral structures, (3) to consider the extent to which volumetric measures are dimorphic in the male and female(More)
Volumetric magnetic resonance image (MRI)-based morphometry was performed on the brains of 30 normal children (15 males and 15 males) with a mean age of 9 years (range 7-11 years). This age range lies in a late but critical phase of brain growth where not volumetric increment will be small but when the details of brain circuity are being fine-tuned to(More)
The origin of astrocytes of the mouse neocortex during the fetal and early postnatal periods as determined by immunocytological, autoradiographic, electron microscopic and antimitotic methods is described. Most astrocytes destined for the white matter and the infragranular cortical layers are derived from the transformation of radial glial cells between P0(More)
Many models of induced ischemic and epileptic tolerance have now been described in the brain. Although detailed mechanisms underlying such protections still remain largely unknown, induction of heat shock proteins is amongst the endogenous responses believed to play an important role in cellular defense mechanisms. This study reveals that the development of(More)
CASE REPORT A case of the antenatal diagnosis of a craniopharyngioma with radical surgery in the neonatal period is reported. REVIEW OF THE LITERATURE We have reviewed the literature of such cases in an attempt to isolate specific features in this age group and to determine the appropriate management. Only six cases of the truly antenatal diagnosis of(More)
AIMS Our objective was to clarify the clinical heterogeneity in Duchenne muscular dystrophy (DMD). METHODS The French dystrophinopathy database provided clinical, histochemical and molecular data of 278 DMD patients (mean longitudinal follow-up: 14.2 years). Diagnosis was based on mutation identification in the DMD gene. Three groups were defined(More)
Congenital muscular dystrophies (CMD) are a clinically and genetically heterogeneous group of muscle disorders, with autosomal recessive inheritance. Absence of the laminin alpha 2 chain in the skeletal muscle of patients with classical CMD has permitted the identification of a subgroup, referred to as 'merosin-deficient CMD or laminin alpha 2 chain(More)
In children, P3 latency decreases with increasing age. This decrease could be linked with the maturation of cognitive processes. According to this hypothesis, event-related potentials P3 were recording in gifted children to research an electrophysiological correlation with the mental precocity. Auditory long latency event-related potentials were recorded in(More)
The objective of this work was to study the natural history of dystrophinopathies and the genotype-phenotype correlations made possible by the development of the clinical part of the French DMD database. The collection of 70,000 clinical data for 600 patients with an average longitudinal follow-up of 12years enabled clarification of the natural history of(More)
