while the presence of certain gnrh neurons with dual actions via collaterals can not be excluded , the results suggest that there are two populations of gnrh neurons , one with access to fenestrated capillaries which is probably related to neurosecretory endocrine regulation of anterior pituitary gonadotropin secretion , and one without access to fenestrated capillaries which is probably related to intracerebral neurotransmission only .
