Doublecortin : A Novel Gene Involved In Cortical Development
A novel gene, Doublecortin, expressed in the fetal
brain and involved in certainmalformations of the cerebral cortex, has just been identified by the Dr. JamelChelly's team at INSERM 129 (directed by Professor Axel Kahn, Paris, France).This should provide insight into how the brain develops and yield...
