Impaired discrimination learning in interneuronal NMDAR-GluN2B mutant mice.

abstract：:GABAA receptors mediate the inhibition of somatostatin release in hypothalamic neurones. To study the possible effect of GABA on somatostatin biosynthesis, somatostatin and preprosomatostatin mRNA levels were evaluated after exposure of hypothalamic neurones to muscimol or bicuculline. Muscimol (50 microM) decreased p...
