Blocking of the sleep-onset associated GH-surge by somatostatin did not affect memory performance but the contribution of growth hormone-releasing hormone (GHRH) to memory processes is unclear. Here we assessed the influence of intranasal GHRH on memory function in waking subjects during the early part of t...
