[Distribution of neurosecretion in the supraoptic and paraventricular nuclei of the cow before and following milking].
Distribution of neurosecretion and enzymes in the nuclei was studied by optical microscopy and histochemical methods. The stimulus of milking had no effect on the amount of secretion in the supraoptic nucleus, but synthesis of secretion in the paraventricular nucleus was stimulated by oxytocin liberation associated with milking, and it was still present 60 minutes after milking. It seems that each nuclear region is a functionally independent unit.
