title: [Biochemical and pharmacological approach to the functional disorders observed in demyelination mutants (GABAergic and noradrenergic systems)].
abstract: The abnormal behavior observed in diseases of myelin remains unexplained. Mutations in the mouse in which the main phenotypic expression involves myelination is a useful tool. As tonic seizures are observed, an electrophysiological, pharmacological and biochemical study was performed. The convulsions seem to be linked mainly to an alteration of the alpha-adrenergic system. The GABA-ergic system is also modified. The relations between these observations and the defect of myelination remain to be elucidated.
