In his experiments Dr. Olney found that high-dose exposure to MSG caused
hypoplasia of the adenohypophysis of the pituitary and of the gonads, in
conjunction with low hypothalamic, pituitary, and plasma levels of LH, growth
hormone, and prolactin. When doses below toxic levels for hypothalamic cells
were used, he found a rapid elevation of LH and a depression of the pulsatile
output of growth hormone. In essence, these excitotoxins can cause severe
pathophysiological changes in the central endocrine control system. Many of
these dysfunctional changes can occur with subtoxic doses of MSG. One can
speculate that chronic exposure to these neurotoxins could cause significant
alterations in the function of the hypothalamus, including its non-endocrine
portions.
