Na*-independent binding of [3H] muscimol to a membrane fraction of the brains of normal and dwarf mice

Abstract

Although their body weights were decreased by about 77% and their brain weights by about 30%, high-affinity [³H] muscimol binding to a cerebral membrane fraction was not altered in hereditary pituitary dwarf mice. Marked changes in the level of pituitary growth-associated hormones do not appear to be associated with a change in cerebral GABA-receptors.
