In 1930 Popa and Fielding described in the rat a specialized network of blood vessels, the hypothalamohypophyseal portal system, that connected the infundibulum (median eminence) and the sinusoids of the pars distalis of the pituitary gland. Its functional importance was not immediately understood. They found no venous drainage from the pituitary gland so they assumed that blood ran from the gland into the brain.
