Neuroectodermal disease involves abnormalities that arise from the ectodermal origin, such as nervous system, eyeball, retina, and skin. Due to rarity of disease, it is often underdiagnosed or misdiagnosed. In this study, researcher presents two cases pediatric patients with no fetomaternal complications who presented focal seizures their initial complaint. During examination, varying skin colo...
The purpose of this article was to review the embryologic stages of the cerebral cortex, illustrate the classification of disorders of cortical formation, and finally describe the main MR imaging features of these disorders. Disorders of cortical formation are classified according to the embryologic stage of the cerebral cortex at which the abnormality occurred. MR imaging shows diminished cort...
A 10-year old boy, product of a non-consanguineous parents presented with developmental delay and poorly controlled seizures. On examination he had features suggestive of atypical growth of the body. There were asymmetric overgrowth of the skull, downward slanting of the palpebral fissures with ptosis, an epibulbar dermoid in the right eye (Figure 1) and a bony tumour (hyperostosis) of the exte...
Spontaneous pacemaker γ-aminobutyric acid (GABA) receptor-mediated synaptic activity (PGA) occurs in a subset of tissue samples from pediatric epilepsy surgery patients. In the present study, based on single-cell electrophysiological recordings from 120 cases, we describe the etiologies, cell types, and primary electrophysiological features of PGA. Cells displaying PGA occurred more frequently ...
A major unanswered question in neuroscience is whether there exists genomic variability between individual neurons of the brain, contributing to functional diversity or to an unexplained burden of neurological disease. To address this question, we developed a method to amplify genomes of single neurons from human brains. Because recent reports suggest frequent LINE-1 (L1) retrotransposition in ...
