Glutamate and GABA levels and glutamate decarboxylase activity in brain regions of rats after prolonged treatment with alkali cations

Resume L'administration chronique des cations des métaux alcalins (Na⁺, Rb⁺, Cs⁺) à les rats a provoqué la croissance des niveaux de glutamate et GABA dans certaines régions du cerveau. On n'a remarqué aucun changement en activité GAD de ces régions.     

Adrenergic neuroplasticity is maintained in the nutritional rehabilitated adult rat

Summary This work examined the capacity of intact catecholaminergic axons to grow, in response to lesions, in the brain of adult rats following nutritional rehabilitation. The partially deafferented epithalamic habenula was used as a model to study neuronal plasticity. Noradrenergic neurons appear to maintain their plasticity in rats recovered from their postnatal undernutrition.Supported by a BRSG-UTMSH grant.Supported by a NIH grant.Acknowledgments.
