[Effect of testosterone on the background impulse activity of the arcuate nucleus neurons of the hypothalamus].
Experiments on pubertal male rats have shown a decrease in the mean frequency of neuronal impulse activity of arcuate hypothalamic nuclei 1 hour after intramuscular injection of oily solution of testosterone propionate. This is one of the possible mechanisms of decreased liberin-producing function of arcuate nuclei, that underlies the negative feed-back control of male sex glands.
