WebApproximately 50–75% of GnRH neurons express the kisspeptin receptor. 34 Kisspeptin acts primarily at the level of the hypothalamus to stimulate GnRH secretion. 35 Nevertheless, a number of studies have demonstrated the ability of kisspeptins to act directly on pituitary gonadotrope cells to stimulate LH release. 36, 37, 38 In 1989, two research groups independently discovered that GnRH neurons, which in adults are scattered throughout the hypothalamus, do not originate in this region of the brain. Instead, they migrate into the brain along olfactory axon fibers from the nose. Most GnRH neurons are born from stem cells in the nasal placode (embryonic nasal tissue). More recently, it was discovered that a subset of GnRH neurons can trace their origins not from the nasal placode, but from the n… skyrim reachwater rock cave
