Abstract
Neurotoxic lesions of the arcuate nucleus by neonatal treatment with monosodium glutamate (MSG) resulted in a decrease of plasma GH levels without affecting plasma corticosterone concentration. The corticoliberin activity of the pituitary stalk median eminence (SME) in MSG-treated animals was similar to that of litter-mate controls. Growth hormone releasing (somatoliberin) activity of the SME, tested after placing an anterolateral cut around the medial basal hypothalamus, was significantly lower in MSG-treated than in control animals. It was concluded that a substantial proportion of the somatoliberin neurones are found in the arcuate nucleus.This publication has 16 references indexed in Scilit:
