Conditioned fear, for example, reduces REM sleep whereas auditory stimulation increases it. [4] In humans, models of stress have been closely linked to the context depression. Changes ...
It produces melatonin, a serotonin-derived hormone, which modulates sleep patterns following the diurnal cycles. [2] The shape of the gland resembles a pine cone , which gives it its name.

Peptide hormones have important influences upon the hypothalamus, and to do so they must pass through the blood–brain barrier. The hypothalamus is bounded in part by specialized brain regions that lack an effective blood–brain barrier; the capillary endothelium at these sites is fenestrated to allow free passage of even large proteins and ...
