INCREASING NEURON NUMBERS IN THE VASOPRESSIN AND OXYTOCIN CONTAINING NUCLEUS OF THE ADULT FEMALE PIG HYPOTHALAMUS

[摘要] Neuron number and volume of the recently described vasopressin and oxytocin containing nucleus (VON) in the pig hypothalamus have been studied into adulthood. Following a 2.5-fold increase in both sexes around puberty, both neuron number and volume of the VON continued to increase in the female pig between 1 and 2.5 years of age. Since no such increase occurred in the male, the VON exhibits a pronounced sexual dimorphism in adulthood of 260%.
