from these findings it is concluded that hypothalamic irs may participate in the hormonal regulatory system in correlation to plasma rgh , as observed in studies on plasma gh and hypothalamic irs following insulin , glucose , propranolol or phentolamine administration , but irs in other regions of the brain may have some other actions as a neurotransmitter or a modulator , because of no significant correlation between plasma gh or prl and irs in these regions following various stimuli .
