Abstract
A 44-year-old man with progressive ataxia, facial weakness, bilateral adduction deficits, and abducting nystagmus was initially misdiagnosed and treated for multiple sclerosis because a midbrain anatomic cleft had been overlooked on brain MRI. Six cases of "midbrain (or mesencephalic) cleft" or "key...

Abstract
Prenatal MRI in congenital central nervous system defects allows to obtain much more important therapeutic data and complement or correct the fetal sonographic diagnosis. Prenatal MRI allows to plan gynaecological, neonatal, neurosurgical treatment, and to predict neurological defects. It also impro...

Abstract
We have generated Sulf1- and Sulf2-deficient mice. Phenotypic analysis of these animals revealed higher embryonic lethality of Sulf2 knockout mice, which can be associated with neuroanatomical malformations during embryogenesis. Sulf1 seems not to be essential for developmental or postnatal viabilit...

Abstract
Among 26,588 births registered in this period, 3.67% presented with malformations (IC=95%; 3.44-3.9), being 0.36% of the CNS (IC=95%,(0.29-0.43)). The most common CNS malformation was meningomielocele (10.4%). Young maternal age (p=0.005); low birth weight (p=0.015); large cephalic perimeter (p=0.00...

Abstract
We have previously reported that mGluR5 signaling via PLC-beta1 regulates the development of whisker patterns within S1 (barrel) cortex of mice (Hannan et al., 2001). However, whether these defects arise from the loss of postsynaptic mGluR5 signaling, and whether the level of mGluR5 is important for...

We show that miR-124a, a nervous-system-specific miRNA, is associated with the Drosophila homolog of FMRP (dFMR1) in vivo. Ectopic expression of wild-type but not mutant miR-124a precursors decreased dendritic branching of dendritic arborization sensory neurons, which was partially rescued by the lo...
